STEEL AND ZINC VERSIONS

T RACErsquos range of linear bearings are setting new standards due to their innovative design and technical concepts The family MONORACE based on different C-shaped rails with a wide range of sliders is offering unique linear solutions for all kinds of automation applications for many industries

T RACErsquos system with roller sliders and internal raceways offer the markets highest performing system along with being size wise the most compact system

The rails of MRG MR and ML series are high precision cold drawn profiles made from steel alloy that with our patented T RACE NOX thermo-chemical hardening process provide a very hard surface for high wear resistance along with and at the same time a good protection against corrosion even in critical environments

HIGH PERFORMANCEThe new rails MRG series rails are the evolution of the consolidated MR series The new rails have a number of improvements related to the contact geometries new materials for increased strength and depth of hardening - T RACE-NOX 20 last generation hardening treatments showing our commitment to continuous technological improvement of T RACE productsThe new MRG43 is companied with a new version MRG46 with increased thicknesses of the flanges to achieve a more rigid rail for critical application where the rail becomes a self-supporting part of the structure The MRG and MR rails allow combinations of different sliders to obtain self-aligning systems based on pairs of rails Such self-aligning system is able to compensate for surface assembly inaccuracies on longitudinal and transverse plane like non precise carpentry aluminum structures or bent sheet metal structures hereby avoiding costly processing machining to achieve precise parallel rail installation The internal raceways with protected roller wheels along with lateral seals and strong wipers incorporating preoiled felts makes the MONORACE linear system very suitable for even harsh ambients - dust humidity etc The rollers of large diameter are rarely sensitive to impurities entering the linear system

STANDARDThe ML series rail represents a simplified version of the MR series with similar dimensions The thinner C shaped rails have the concave inner raceways in which slide rollers of single row bearing with shields and inner ball cage made in metal The carriages in various versions are equipped with wipers with lubricating felt The ML series does not provide self-aligning features

COST EFFECTIVELAN rails are made from sheet steel and shaped by high precision ultra-smooth forming rollers They are then case hardened using our revolutionary TRACE-NOX nitriding and black oxidising process to ensure an extended lifetime and excellent corrosion resistanceThe slider bodies are cataphoretically blackened for maximum corrosion resistance The rollers are made from core tempered and precision ground bearing grade steel The ball bearings are lubricated for life with wide temperature range bearing grease and protected by 2Z rated metal shields Robust elastomer raceway wipers are fitted at both ends of the slider to protect the rollers and keep the raceways clean The wipers incorporate oil-impregnated felt pads to keep the points of contact between raceway and roller properly lubricated for the lifetime of the rail Wipers are held in place by a simple clip and can be removed and replaced easily

INOXLAX series rails and PAX series sliders are constructed entirely of stainless steel and are a simple and functional solution for applicationsthat require high corrosion resistance The rails and sliders bodies are made from 300 Series stainless with rollers made from 440C These are particularly suitable for food processing pharmaceutical and medical applications or in difficult environments such as marine environments where there is exposure to highly corrosive agents The slider is equipped with 3 rollers The middle roller is eccentric and is used to adjust the slider preload The sliders are easily washable for applications subject to frequent cleaning and do not release particles into the environment and are particularly suitable for clean rooms They are available in two sections 26 and 40 mm

The roller linear MODULAR system FLEXRACE offers the maximum flexibility configuration due to the original shape of the guide FXRG basic component of the system shaped with 3 raceways arranged at 90 deg to each other on which can slide the rollers RG 43 series indifferently on each of the three raceways The using of the single guide or two or more parallel guides gives rise to a number of combinations capable of satisfying each specific need for linear motion and offering exceptional ability to self-alignment Like the MONORACErsquos MR amp ML rails FXRG rail is constructed in high strength steel hardened with the last generation T RACE NOX 20 hardening treatments for a further improvement of the performance and durability

The ball cage linear slide HIGH LOAD of SF series offers a very high load capacity in a compact size They are built from the base of the rail ML series with one or more sliders that move through the interposition of one or more robust ball cages with large diameter balls Like the MONORACE rails are made by the same production process and hardened with thermochemical process patented T RACE NOX 10 They are suitable for horizontal movements with high loads in all directions and for movements where the stroke available is completely used

RACEWAY CONTACT OF ROLLERS FOR MR AND MRG RAILS

ROLLER POSITIONING

Sliders are available with either 3 or 5 rollers For the 3 roller version the first and third roller are fixed concentric rollers that run on the same raceway The second roller is eccentric and runs on the opposite racewayThe eccentric feature is used to adjust the slider preload in the railFor the 5 roller version the two lateral and the central roller are fixed and run on the same racewayThe second and fourth roller are eccentric and run on the opposite raceway The eccentric feature is used to adjust the slider preload in the rail Because one raceway contacts more rollers than the other raceway the sliders have a preferred loading directionThe slider is marked with two small circular notches indicating the direction with the most rollers and direction of preferred loading Care during assembly is required to ensure the maximum load capacity of the system is achieved

3-ROLLER SLIDER

5-ROLLER SLIDER

The rollers used in the sliders consist of three different geometries to achieve different levels of constraint within the railrsquos raceways

The guiding rollers RCV (concentric) REV (eccentric) are in contact with the raceways by 2 contact-points hereby creating well constrained rollers on the raceway both in radial and axial direction

The Floating Rollers RCP (concentric) REP (eccentric) engage only the peak of the raceway which constrains it radially but allows it to float in the axial direction between the two shoulders The roller can also rotate a little

The Flat full Floating Rollers RCU (concentric) REU (eccentric) engage only the peak of the raceway which constrains it radially but allows it to Float completely free in the axial direction without limitation Being completely cylindrical It allows axial travel to be wider than RP-version but being free from lateral shoulders it can run out of the rail or against the bottom railwhen exceeding the nominal floating capacity The Roller can also rotate a little

THE GUIDING SLIDERS RV

By utilizing all guiding rollers RVRVS sliders are obtained These sliders are completely constrained and will support loads and moments in all directions with the greatest capacity in the radial direction

THE FLOATING SLIDERS RP

By utilizing all floating rollers RPRPS sliders are obtained These sliders are able to carry full radial load while floating and rotating a bit without affecting the preload or the smooth running quality to eliminate eventual binding problems typical for recirculating ball-bearing sliders

THE EXTRA FLOATING RU

By utilizing all full flat floating rollers RU RUS sliders are obtained These sliders are able to carry full radial load while floating and rotating a bit without affecting the preload or the smooth running quality too eliminating eventual binding problems typical for recirculating ball-bearing slidersExtra Floating sliders are used in 2 rail systems to absorb larger parallelism errors in the mounting surfacesBeing completely cylindrical free from lateral shoulders it can run out of the rail or against the bottom rail when exceeding the nominal floating capacity The slider can too rotate a bit

THE ROTATING RA

By mixing guiding and floating rollers RA RAS sliders are obtained These sliders are able to carry full radial load while rotating a bit without affecting the preload or the smooth running quality meanwhile allowing for precise movement These sliders also retain the ability to guide the payload as it travels Rotating sliders are used in 2 rail systems to absorb angular errors in the mounting surfaces that cause traditional bearings to bindNew RAGRAGS sliders with MRG4346 rails offer greater rotation capacity compared with RA sliders with MR43 rails

TECHNICAL FEATURES

The MRG Series Rails are available with two types of mounting holes bull MRG L with counterbored mounting holes for special low head TORX mounting screws that are provided with the rail bull MRG S with countersunk mounting holes for UNI-standard ISO5933 common screws The rail has a ldquoCrdquo shaped cross-section with interior convex raceways The convex raceways are polished for smooth low noise movement The interior raceways are protected from accidental bumps and other damages that might ruin the raceway surface The shape also protects the rollers from similar types of damage MRG Rails are made from high strength steel that is hardened through the innovative TRACE-NOX 20 high depth nitriding process and afterwards with black oxidation that provides an excellent corrosion resistance This treatment is not a plating which can flake off but instead penetrates and alters the material surface The result is a very hard and durable corrosion resistance linear rail that is black in color due to the micro impregnation of oil and antioxidants

LINEAR SELFALIGNMENT SYSTEM WITH MR RAILS AND R RS SLIDERS

The system is based on C-shaped profile with internal raceways and sliders with double row bearings with different numbers and types of rollers according to different load capacities and fixing possibilities

The precision rollers are lubricated for life and with 2RS seals The sliders come in version with 3 or 5 rollers for which some with Eccentric pivot for preload setting The sliders have mounted strong wipers with preoiled felt for good cleaninglubrication of raceways to provide for long maintenance freeoperation

The turning parts are all well protected within the internal raceways and betweenthe wipers to provide the markets most compact and well protected linear rollersystem

The careful finish of the raceways and the build quality of components allow the use of high-speed linear guide up to 10m s with a low noise levelThe self-aligning compositions are illustrated in 14-17 pages

TECHNICAL FEATURES

The MR Series Rails are available with two types of mounting holes bull MR L with counterbored mounting holes for special low head TORX mounting screws that are provided with the rail bull MR S with countersunk mounting holes for UNI-standard ISO5933 common screws The rail has a ldquoCrdquo shaped cross-section with interior convex raceways The convex raceways are polished for smooth low noise movement The interior raceways are protected from accidental bumps and other damage that might ruin the raceway surface The shape also protects the rollers from similar types of damage MR Rails are made from high strength steel that is hardened through the innovative TRACE-NOX 10 high depth nitride hardening process and with an afterwards black oxidation that provides an excellent corrosion resistance This treatment is not a plating which can flake off but instead penetrates and al-ters the material surface The result is a very hard and durable corrosion resistance linear rail that is black in color due to the micro impregnation of oil and antioxidants

STEEL AND ZINC VERSIONS

T RACErsquos range of linear bearings are setting new standards due to their innovative design and technical concepts The family MONORACE based on different C-shaped rails with a wide range of sliders is offering unique linear solutions for all kinds of automation applications for many industries

T RACErsquos system with roller sliders and internal raceways offer the markets highest performing system along with being size wise the most compact system

The rails of MRG MR and ML series are high precision cold drawn profiles made from steel alloy that with our patented T RACE NOX thermo-chemical hardening process provide a very hard surface for high wear resistance along with and at the same time a good protection against corrosion even in critical environments

HIGH PERFORMANCEThe new rails MRG series rails are the evolution of the consolidated MR series The new rails have a number of improvements related to the contact geometries new materials for increased strength and depth of hardening - T RACE-NOX 20 last generation hardening treatments showing our commitment to continuous technological improvement of T RACE productsThe new MRG43 is companied with a new version MRG46 with increased thicknesses of the flanges to achieve a more rigid rail for critical application where the rail becomes a self-supporting part of the structure The MRG and MR rails allow combinations of different sliders to obtain self-aligning systems based on pairs of rails Such self-aligning system is able to compensate for surface assembly inaccuracies on longitudinal and transverse plane like non precise carpentry aluminum structures or bent sheet metal structures hereby avoiding costly processing machining to achieve precise parallel rail installation The internal raceways with protected roller wheels along with lateral seals and strong wipers incorporating preoiled felts makes the MONORACE linear system very suitable for even harsh ambients - dust humidity etc The rollers of large diameter are rarely sensitive to impurities entering the linear system

STANDARDThe ML series rail represents a simplified version of the MR series with similar dimensions The thinner C shaped rails have the concave inner raceways in which slide rollers of single row bearing with shields and inner ball cage made in metal The carriages in various versions are equipped with wipers with lubricating felt The ML series does not provide self-aligning features

COST EFFECTIVELAN rails are made from sheet steel and shaped by high precision ultra-smooth forming rollers They are then case hardened using our revolutionary TRACE-NOX nitriding and black oxidising process to ensure an extended lifetime and excellent corrosion resistanceThe slider bodies are cataphoretically blackened for maximum corrosion resistance The rollers are made from core tempered and precision ground bearing grade steel The ball bearings are lubricated for life with wide temperature range bearing grease and protected by 2Z rated metal shields Robust elastomer raceway wipers are fitted at both ends of the slider to protect the rollers and keep the raceways clean The wipers incorporate oil-impregnated felt pads to keep the points of contact between raceway and roller properly lubricated for the lifetime of the rail Wipers are held in place by a simple clip and can be removed and replaced easily

INOXLAX series rails and PAX series sliders are constructed entirely of stainless steel and are a simple and functional solution for applicationsthat require high corrosion resistance The rails and sliders bodies are made from 300 Series stainless with rollers made from 440C These are particularly suitable for food processing pharmaceutical and medical applications or in difficult environments such as marine environments where there is exposure to highly corrosive agents The slider is equipped with 3 rollers The middle roller is eccentric and is used to adjust the slider preload The sliders are easily washable for applications subject to frequent cleaning and do not release particles into the environment and are particularly suitable for clean rooms They are available in two sections 26 and 40 mm

The roller linear MODULAR system FLEXRACE offers the maximum flexibility configuration due to the original shape of the guide FXRG basic component of the system shaped with 3 raceways arranged at 90 deg to each other on which can slide the rollers RG 43 series indifferently on each of the three raceways The using of the single guide or two or more parallel guides gives rise to a number of combinations capable of satisfying each specific need for linear motion and offering exceptional ability to self-alignment Like the MONORACErsquos MR amp ML rails FXRG rail is constructed in high strength steel hardened with the last generation T RACE NOX 20 hardening treatments for a further improvement of the performance and durability

The ball cage linear slide HIGH LOAD of SF series offers a very high load capacity in a compact size They are built from the base of the rail ML series with one or more sliders that move through the interposition of one or more robust ball cages with large diameter balls Like the MONORACE rails are made by the same production process and hardened with thermochemical process patented T RACE NOX 10 They are suitable for horizontal movements with high loads in all directions and for movements where the stroke available is completely used

RACEWAY CONTACT OF ROLLERS FOR MR AND MRG RAILS

ROLLER POSITIONING

Sliders are available with either 3 or 5 rollers For the 3 roller version the first and third roller are fixed concentric rollers that run on the same raceway The second roller is eccentric and runs on the opposite racewayThe eccentric feature is used to adjust the slider preload in the railFor the 5 roller version the two lateral and the central roller are fixed and run on the same racewayThe second and fourth roller are eccentric and run on the opposite raceway The eccentric feature is used to adjust the slider preload in the rail Because one raceway contacts more rollers than the other raceway the sliders have a preferred loading directionThe slider is marked with two small circular notches indicating the direction with the most rollers and direction of preferred loading Care during assembly is required to ensure the maximum load capacity of the system is achieved

3-ROLLER SLIDER

5-ROLLER SLIDER

The rollers used in the sliders consist of three different geometries to achieve different levels of constraint within the railrsquos raceways

The guiding rollers RCV (concentric) REV (eccentric) are in contact with the raceways by 2 contact-points hereby creating well constrained rollers on the raceway both in radial and axial direction

The Floating Rollers RCP (concentric) REP (eccentric) engage only the peak of the raceway which constrains it radially but allows it to float in the axial direction between the two shoulders The roller can also rotate a little

The Flat full Floating Rollers RCU (concentric) REU (eccentric) engage only the peak of the raceway which constrains it radially but allows it to Float completely free in the axial direction without limitation Being completely cylindrical It allows axial travel to be wider than RP-version but being free from lateral shoulders it can run out of the rail or against the bottom railwhen exceeding the nominal floating capacity The Roller can also rotate a little

TECHNICAL FEATURES

The MRG Series Rails are available with two types of mounting holes bull MRG L with counterbored mounting holes for special low head TORX mounting screws that are provided with the rail bull MRG S with countersunk mounting holes for UNI-standard ISO5933 common screws The rail has a ldquoCrdquo shaped cross-section with interior convex raceways The convex raceways are polished for smooth low noise movement The interior raceways are protected from accidental bumps and other damages that might ruin the raceway surface The shape also protects the rollers from similar types of damage MRG Rails are made from high strength steel that is hardened through the innovative TRACE-NOX 20 high depth nitriding process and afterwards with black oxidation that provides an excellent corrosion resistance This treatment is not a plating which can flake off but instead penetrates and alters the material surface The result is a very hard and durable corrosion resistance linear rail that is black in color due to the micro impregnation of oil and antioxidants

LINEAR SELFALIGNMENT SYSTEM WITH MR RAILS AND R RS SLIDERS

The system is based on C-shaped profile with internal raceways and sliders with double row bearings with different numbers and types of rollers according to different load capacities and fixing possibilities

The precision rollers are lubricated for life and with 2RS seals The sliders come in version with 3 or 5 rollers for which some with Eccentric pivot for preload setting The sliders have mounted strong wipers with preoiled felt for good cleaninglubrication of raceways to provide for long maintenance freeoperation

The turning parts are all well protected within the internal raceways and betweenthe wipers to provide the markets most compact and well protected linear rollersystem

The careful finish of the raceways and the build quality of components allow the use of high-speed linear guide up to 10m s with a low noise levelThe self-aligning compositions are illustrated in 14-17 pages

TECHNICAL FEATURES

The MR Series Rails are available with two types of mounting holes bull MR L with counterbored mounting holes for special low head TORX mounting screws that are provided with the rail bull MR S with countersunk mounting holes for UNI-standard ISO5933 common screws The rail has a ldquoCrdquo shaped cross-section with interior convex raceways The convex raceways are polished for smooth low noise movement The interior raceways are protected from accidental bumps and other damage that might ruin the raceway surface The shape also protects the rollers from similar types of damage MR Rails are made from high strength steel that is hardened through the innovative TRACE-NOX 10 high depth nitride hardening process and with an afterwards black oxidation that provides an excellent corrosion resistance This treatment is not a plating which can flake off but instead penetrates and al-ters the material surface The result is a very hard and durable corrosion resistance linear rail that is black in color due to the micro impregnation of oil and antioxidants

STEEL AND ZINC VERSIONS

T RACErsquos range of linear bearings are setting new standards due to their innovative design and technical concepts The family MONORACE based on different C-shaped rails with a wide range of sliders is offering unique linear solutions for all kinds of automation applications for many industries

T RACErsquos system with roller sliders and internal raceways offer the markets highest performing system along with being size wise the most compact system

The rails of MRG MR and ML series are high precision cold drawn profiles made from steel alloy that with our patented T RACE NOX thermo-chemical hardening process provide a very hard surface for high wear resistance along with and at the same time a good protection against corrosion even in critical environments

HIGH PERFORMANCEThe new rails MRG series rails are the evolution of the consolidated MR series The new rails have a number of improvements related to the contact geometries new materials for increased strength and depth of hardening - T RACE-NOX 20 last generation hardening treatments showing our commitment to continuous technological improvement of T RACE productsThe new MRG43 is companied with a new version MRG46 with increased thicknesses of the flanges to achieve a more rigid rail for critical application where the rail becomes a self-supporting part of the structure The MRG and MR rails allow combinations of different sliders to obtain self-aligning systems based on pairs of rails Such self-aligning system is able to compensate for surface assembly inaccuracies on longitudinal and transverse plane like non precise carpentry aluminum structures or bent sheet metal structures hereby avoiding costly processing machining to achieve precise parallel rail installation The internal raceways with protected roller wheels along with lateral seals and strong wipers incorporating preoiled felts makes the MONORACE linear system very suitable for even harsh ambients - dust humidity etc The rollers of large diameter are rarely sensitive to impurities entering the linear system

STANDARDThe ML series rail represents a simplified version of the MR series with similar dimensions The thinner C shaped rails have the concave inner raceways in which slide rollers of single row bearing with shields and inner ball cage made in metal The carriages in various versions are equipped with wipers with lubricating felt The ML series does not provide self-aligning features

COST EFFECTIVELAN rails are made from sheet steel and shaped by high precision ultra-smooth forming rollers They are then case hardened using our revolutionary TRACE-NOX nitriding and black oxidising process to ensure an extended lifetime and excellent corrosion resistanceThe slider bodies are cataphoretically blackened for maximum corrosion resistance The rollers are made from core tempered and precision ground bearing grade steel The ball bearings are lubricated for life with wide temperature range bearing grease and protected by 2Z rated metal shields Robust elastomer raceway wipers are fitted at both ends of the slider to protect the rollers and keep the raceways clean The wipers incorporate oil-impregnated felt pads to keep the points of contact between raceway and roller properly lubricated for the lifetime of the rail Wipers are held in place by a simple clip and can be removed and replaced easily

INOXLAX series rails and PAX series sliders are constructed entirely of stainless steel and are a simple and functional solution for applicationsthat require high corrosion resistance The rails and sliders bodies are made from 300 Series stainless with rollers made from 440C These are particularly suitable for food processing pharmaceutical and medical applications or in difficult environments such as marine environments where there is exposure to highly corrosive agents The slider is equipped with 3 rollers The middle roller is eccentric and is used to adjust the slider preload The sliders are easily washable for applications subject to frequent cleaning and do not release particles into the environment and are particularly suitable for clean rooms They are available in two sections 26 and 40 mm

The roller linear MODULAR system FLEXRACE offers the maximum flexibility configuration due to the original shape of the guide FXRG basic component of the system shaped with 3 raceways arranged at 90 deg to each other on which can slide the rollers RG 43 series indifferently on each of the three raceways The using of the single guide or two or more parallel guides gives rise to a number of combinations capable of satisfying each specific need for linear motion and offering exceptional ability to self-alignment Like the MONORACErsquos MR amp ML rails FXRG rail is constructed in high strength steel hardened with the last generation T RACE NOX 20 hardening treatments for a further improvement of the performance and durability

The ball cage linear slide HIGH LOAD of SF series offers a very high load capacity in a compact size They are built from the base of the rail ML series with one or more sliders that move through the interposition of one or more robust ball cages with large diameter balls Like the MONORACE rails are made by the same production process and hardened with thermochemical process patented T RACE NOX 10 They are suitable for horizontal movements with high loads in all directions and for movements where the stroke available is completely used

RACEWAY CONTACT OF ROLLERS FOR MR AND MRG RAILS

ROLLER POSITIONING

Sliders are available with either 3 or 5 rollers For the 3 roller version the first and third roller are fixed concentric rollers that run on the same raceway The second roller is eccentric and runs on the opposite racewayThe eccentric feature is used to adjust the slider preload in the railFor the 5 roller version the two lateral and the central roller are fixed and run on the same racewayThe second and fourth roller are eccentric and run on the opposite raceway The eccentric feature is used to adjust the slider preload in the rail Because one raceway contacts more rollers than the other raceway the sliders have a preferred loading directionThe slider is marked with two small circular notches indicating the direction with the most rollers and direction of preferred loading Care during assembly is required to ensure the maximum load capacity of the system is achieved

3-ROLLER SLIDER

5-ROLLER SLIDER

The rollers used in the sliders consist of three different geometries to achieve different levels of constraint within the railrsquos raceways

The guiding rollers RCV (concentric) REV (eccentric) are in contact with the raceways by 2 contact-points hereby creating well constrained rollers on the raceway both in radial and axial direction

The Floating Rollers RCP (concentric) REP (eccentric) engage only the peak of the raceway which constrains it radially but allows it to float in the axial direction between the two shoulders The roller can also rotate a little

The Flat full Floating Rollers RCU (concentric) REU (eccentric) engage only the peak of the raceway which constrains it radially but allows it to Float completely free in the axial direction without limitation Being completely cylindrical It allows axial travel to be wider than RP-version but being free from lateral shoulders it can run out of the rail or against the bottom railwhen exceeding the nominal floating capacity The Roller can also rotate a little

TECHNICAL FEATURES

The MRG Series Rails are available with two types of mounting holes bull MRG L with counterbored mounting holes for special low head TORX mounting screws that are provided with the rail bull MRG S with countersunk mounting holes for UNI-standard ISO5933 common screws The rail has a ldquoCrdquo shaped cross-section with interior convex raceways The convex raceways are polished for smooth low noise movement The interior raceways are protected from accidental bumps and other damages that might ruin the raceway surface The shape also protects the rollers from similar types of damage MRG Rails are made from high strength steel that is hardened through the innovative TRACE-NOX 20 high depth nitriding process and afterwards with black oxidation that provides an excellent corrosion resistance This treatment is not a plating which can flake off but instead penetrates and alters the material surface The result is a very hard and durable corrosion resistance linear rail that is black in color due to the micro impregnation of oil and antioxidants

LINEAR SELFALIGNMENT SYSTEM WITH MR RAILS AND R RS SLIDERS

The system is based on C-shaped profile with internal raceways and sliders with double row bearings with different numbers and types of rollers according to different load capacities and fixing possibilities

The precision rollers are lubricated for life and with 2RS seals The sliders come in version with 3 or 5 rollers for which some with Eccentric pivot for preload setting The sliders have mounted strong wipers with preoiled felt for good cleaninglubrication of raceways to provide for long maintenance freeoperation

The turning parts are all well protected within the internal raceways and betweenthe wipers to provide the markets most compact and well protected linear rollersystem

The careful finish of the raceways and the build quality of components allow the use of high-speed linear guide up to 10m s with a low noise levelThe self-aligning compositions are illustrated in 14-17 pages

TECHNICAL FEATURES

The MR Series Rails are available with two types of mounting holes bull MR L with counterbored mounting holes for special low head TORX mounting screws that are provided with the rail bull MR S with countersunk mounting holes for UNI-standard ISO5933 common screws The rail has a ldquoCrdquo shaped cross-section with interior convex raceways The convex raceways are polished for smooth low noise movement The interior raceways are protected from accidental bumps and other damage that might ruin the raceway surface The shape also protects the rollers from similar types of damage MR Rails are made from high strength steel that is hardened through the innovative TRACE-NOX 10 high depth nitride hardening process and with an afterwards black oxidation that provides an excellent corrosion resistance This treatment is not a plating which can flake off but instead penetrates and al-ters the material surface The result is a very hard and durable corrosion resistance linear rail that is black in color due to the micro impregnation of oil and antioxidants

Page 4: DISCOVER THE NATURAL STRENGTH OF THE BEST ROLLER … · “HIGH PERFORMANCE” LINEAR ROLLER SLIDE MRG-MR SERIES “STANDARD” LINEAR ROLLER SLIDER ML SERIES LAN 26 LAN 30 LAN 40

T RACErsquos range of linear bearings are setting new standards due to their innovative design and technical concepts The family MONORACE based on different C-shaped rails with a wide range of sliders is offering unique linear solutions for all kinds of automation applications for many industries

T RACErsquos system with roller sliders and internal raceways offer the markets highest performing system along with being size wise the most compact system

The rails of MRG MR and ML series are high precision cold drawn profiles made from steel alloy that with our patented T RACE NOX thermo-chemical hardening process provide a very hard surface for high wear resistance along with and at the same time a good protection against corrosion even in critical environments

HIGH PERFORMANCEThe new rails MRG series rails are the evolution of the consolidated MR series The new rails have a number of improvements related to the contact geometries new materials for increased strength and depth of hardening - T RACE-NOX 20 last generation hardening treatments showing our commitment to continuous technological improvement of T RACE productsThe new MRG43 is companied with a new version MRG46 with increased thicknesses of the flanges to achieve a more rigid rail for critical application where the rail becomes a self-supporting part of the structure The MRG and MR rails allow combinations of different sliders to obtain self-aligning systems based on pairs of rails Such self-aligning system is able to compensate for surface assembly inaccuracies on longitudinal and transverse plane like non precise carpentry aluminum structures or bent sheet metal structures hereby avoiding costly processing machining to achieve precise parallel rail installation The internal raceways with protected roller wheels along with lateral seals and strong wipers incorporating preoiled felts makes the MONORACE linear system very suitable for even harsh ambients - dust humidity etc The rollers of large diameter are rarely sensitive to impurities entering the linear system

STANDARDThe ML series rail represents a simplified version of the MR series with similar dimensions The thinner C shaped rails have the concave inner raceways in which slide rollers of single row bearing with shields and inner ball cage made in metal The carriages in various versions are equipped with wipers with lubricating felt The ML series does not provide self-aligning features

COST EFFECTIVELAN rails are made from sheet steel and shaped by high precision ultra-smooth forming rollers They are then case hardened using our revolutionary TRACE-NOX nitriding and black oxidising process to ensure an extended lifetime and excellent corrosion resistanceThe slider bodies are cataphoretically blackened for maximum corrosion resistance The rollers are made from core tempered and precision ground bearing grade steel The ball bearings are lubricated for life with wide temperature range bearing grease and protected by 2Z rated metal shields Robust elastomer raceway wipers are fitted at both ends of the slider to protect the rollers and keep the raceways clean The wipers incorporate oil-impregnated felt pads to keep the points of contact between raceway and roller properly lubricated for the lifetime of the rail Wipers are held in place by a simple clip and can be removed and replaced easily

INOXLAX series rails and PAX series sliders are constructed entirely of stainless steel and are a simple and functional solution for applicationsthat require high corrosion resistance The rails and sliders bodies are made from 300 Series stainless with rollers made from 440C These are particularly suitable for food processing pharmaceutical and medical applications or in difficult environments such as marine environments where there is exposure to highly corrosive agents The slider is equipped with 3 rollers The middle roller is eccentric and is used to adjust the slider preload The sliders are easily washable for applications subject to frequent cleaning and do not release particles into the environment and are particularly suitable for clean rooms They are available in two sections 26 and 40 mm

The roller linear MODULAR system FLEXRACE offers the maximum flexibility configuration due to the original shape of the guide FXRG basic component of the system shaped with 3 raceways arranged at 90 deg to each other on which can slide the rollers RG 43 series indifferently on each of the three raceways The using of the single guide or two or more parallel guides gives rise to a number of combinations capable of satisfying each specific need for linear motion and offering exceptional ability to self-alignment Like the MONORACErsquos MR amp ML rails FXRG rail is constructed in high strength steel hardened with the last generation T RACE NOX 20 hardening treatments for a further improvement of the performance and durability

The ball cage linear slide HIGH LOAD of SF series offers a very high load capacity in a compact size They are built from the base of the rail ML series with one or more sliders that move through the interposition of one or more robust ball cages with large diameter balls Like the MONORACE rails are made by the same production process and hardened with thermochemical process patented T RACE NOX 10 They are suitable for horizontal movements with high loads in all directions and for movements where the stroke available is completely used

RACEWAY CONTACT OF ROLLERS FOR MR AND MRG RAILS

ROLLER POSITIONING

Sliders are available with either 3 or 5 rollers For the 3 roller version the first and third roller are fixed concentric rollers that run on the same raceway The second roller is eccentric and runs on the opposite racewayThe eccentric feature is used to adjust the slider preload in the railFor the 5 roller version the two lateral and the central roller are fixed and run on the same racewayThe second and fourth roller are eccentric and run on the opposite raceway The eccentric feature is used to adjust the slider preload in the rail Because one raceway contacts more rollers than the other raceway the sliders have a preferred loading directionThe slider is marked with two small circular notches indicating the direction with the most rollers and direction of preferred loading Care during assembly is required to ensure the maximum load capacity of the system is achieved

3-ROLLER SLIDER

5-ROLLER SLIDER

The rollers used in the sliders consist of three different geometries to achieve different levels of constraint within the railrsquos raceways

The guiding rollers RCV (concentric) REV (eccentric) are in contact with the raceways by 2 contact-points hereby creating well constrained rollers on the raceway both in radial and axial direction

The Floating Rollers RCP (concentric) REP (eccentric) engage only the peak of the raceway which constrains it radially but allows it to float in the axial direction between the two shoulders The roller can also rotate a little

The Flat full Floating Rollers RCU (concentric) REU (eccentric) engage only the peak of the raceway which constrains it radially but allows it to Float completely free in the axial direction without limitation Being completely cylindrical It allows axial travel to be wider than RP-version but being free from lateral shoulders it can run out of the rail or against the bottom railwhen exceeding the nominal floating capacity The Roller can also rotate a little

LINEAR SELFALIGNMENT SYSTEM WITH MR RAILS AND R RS SLIDERS

The system is based on C-shaped profile with internal raceways and sliders with double row bearings with different numbers and types of rollers according to different load capacities and fixing possibilities

The precision rollers are lubricated for life and with 2RS seals The sliders come in version with 3 or 5 rollers for which some with Eccentric pivot for preload setting The sliders have mounted strong wipers with preoiled felt for good cleaninglubrication of raceways to provide for long maintenance freeoperation

The turning parts are all well protected within the internal raceways and betweenthe wipers to provide the markets most compact and well protected linear rollersystem

The careful finish of the raceways and the build quality of components allow the use of high-speed linear guide up to 10m s with a low noise levelThe self-aligning compositions are illustrated in 14-17 pages

TECHNICAL FEATURES

The MR Series Rails are available with two types of mounting holes bull MR L with counterbored mounting holes for special low head TORX mounting screws that are provided with the rail bull MR S with countersunk mounting holes for UNI-standard ISO5933 common screws The rail has a ldquoCrdquo shaped cross-section with interior convex raceways The convex raceways are polished for smooth low noise movement The interior raceways are protected from accidental bumps and other damage that might ruin the raceway surface The shape also protects the rollers from similar types of damage MR Rails are made from high strength steel that is hardened through the innovative TRACE-NOX 10 high depth nitride hardening process and with an afterwards black oxidation that provides an excellent corrosion resistance This treatment is not a plating which can flake off but instead penetrates and al-ters the material surface The result is a very hard and durable corrosion resistance linear rail that is black in color due to the micro impregnation of oil and antioxidants

RACEWAY CONTACT OF ROLLERS FOR MR AND MRG RAILS

ROLLER POSITIONING

Sliders are available with either 3 or 5 rollers For the 3 roller version the first and third roller are fixed concentric rollers that run on the same raceway The second roller is eccentric and runs on the opposite racewayThe eccentric feature is used to adjust the slider preload in the railFor the 5 roller version the two lateral and the central roller are fixed and run on the same racewayThe second and fourth roller are eccentric and run on the opposite raceway The eccentric feature is used to adjust the slider preload in the rail Because one raceway contacts more rollers than the other raceway the sliders have a preferred loading directionThe slider is marked with two small circular notches indicating the direction with the most rollers and direction of preferred loading Care during assembly is required to ensure the maximum load capacity of the system is achieved

3-ROLLER SLIDER

5-ROLLER SLIDER

The rollers used in the sliders consist of three different geometries to achieve different levels of constraint within the railrsquos raceways

The guiding rollers RCV (concentric) REV (eccentric) are in contact with the raceways by 2 contact-points hereby creating well constrained rollers on the raceway both in radial and axial direction

The Floating Rollers RCP (concentric) REP (eccentric) engage only the peak of the raceway which constrains it radially but allows it to float in the axial direction between the two shoulders The roller can also rotate a little

The Flat full Floating Rollers RCU (concentric) REU (eccentric) engage only the peak of the raceway which constrains it radially but allows it to Float completely free in the axial direction without limitation Being completely cylindrical It allows axial travel to be wider than RP-version but being free from lateral shoulders it can run out of the rail or against the bottom railwhen exceeding the nominal floating capacity The Roller can also rotate a little

COMPOSITION SLIDERS SERIES R and RG

THE GUIDING SLIDERS RV

By utilizing all guiding rollers RVRVS sliders are obtained These sliders are completely constrained and will support loads and moments in all directions with the greatest capacity in the radial direction

THE FLOATING SLIDERS RP

By utilizing all floating rollers RPRPS sliders are obtained These sliders are able to carry full radial load while floating and rotating a bit without affecting the preload or the smooth running quality to eliminate eventual binding problems typical for recirculating ball-bearing sliders

THE EXTRA FLOATING RU

By utilizing all full flat floating rollers RU RUS sliders are obtained These sliders are able to carry full radial load while floating and rotating a bit without affecting the preload or the smooth running quality too eliminating eventual binding problems typical for recirculating ball-bearing slidersExtra Floating sliders are used in 2 rail systems to absorb larger parallelism errors in the mounting surfacesBeing completely cylindrical free from lateral shoulders it can run out of the rail or against the bottom rail when exceeding the nominal floating capacity The slider can too rotate a bit

THE ROTATING RA

By mixing guiding and floating rollers RA RAS sliders are obtained These sliders are able to carry full radial load while rotating a bit without affecting the preload or the smooth running quality meanwhile allowing for precise movement These sliders also retain the ability to guide the payload as it travels Rotating sliders are used in 2 rail systems to absorb angular errors in the mounting surfaces that cause traditional bearings to bindNew RAGRAGS sliders with MRG4346 rails offer greater rotation capacity compared with RA sliders with MR43 rails

TECHNICAL FEATURES

The MRG Series Rails are available with two types of mounting holes bull MRG L with counterbored mounting holes for special low head TORX mounting screws that are provided with the rail bull MRG S with countersunk mounting holes for UNI-standard ISO5933 common screws The rail has a ldquoCrdquo shaped cross-section with interior convex raceways The convex raceways are polished for smooth low noise movement The interior raceways are protected from accidental bumps and other damages that might ruin the raceway surface The shape also protects the rollers from similar types of damage MRG Rails are made from high strength steel that is hardened through the innovative TRACE-NOX 20 high depth nitriding process and afterwards with black oxidation that provides an excellent corrosion resistance This treatment is not a plating which can flake off but instead penetrates and alters the material surface The result is a very hard and durable corrosion resistance linear rail that is black in color due to the micro impregnation of oil and antioxidants

LINEAR SELFALIGNMENT SYSTEM WITH MR RAILS AND R RS SLIDERS

The system is based on C-shaped profile with internal raceways and sliders with double row bearings with different numbers and types of rollers according to different load capacities and fixing possibilities

The precision rollers are lubricated for life and with 2RS seals The sliders come in version with 3 or 5 rollers for which some with Eccentric pivot for preload setting The sliders have mounted strong wipers with preoiled felt for good cleaninglubrication of raceways to provide for long maintenance freeoperation

The turning parts are all well protected within the internal raceways and betweenthe wipers to provide the markets most compact and well protected linear rollersystem

The careful finish of the raceways and the build quality of components allow the use of high-speed linear guide up to 10m s with a low noise levelThe self-aligning compositions are illustrated in 14-17 pages

TECHNICAL FEATURES

The MR Series Rails are available with two types of mounting holes bull MR L with counterbored mounting holes for special low head TORX mounting screws that are provided with the rail bull MR S with countersunk mounting holes for UNI-standard ISO5933 common screws The rail has a ldquoCrdquo shaped cross-section with interior convex raceways The convex raceways are polished for smooth low noise movement The interior raceways are protected from accidental bumps and other damage that might ruin the raceway surface The shape also protects the rollers from similar types of damage MR Rails are made from high strength steel that is hardened through the innovative TRACE-NOX 10 high depth nitride hardening process and with an afterwards black oxidation that provides an excellent corrosion resistance This treatment is not a plating which can flake off but instead penetrates and al-ters the material surface The result is a very hard and durable corrosion resistance linear rail that is black in color due to the micro impregnation of oil and antioxidants

RACEWAY CONTACT OF ROLLERS FOR MR AND MRG RAILS

ROLLER POSITIONING

Sliders are available with either 3 or 5 rollers For the 3 roller version the first and third roller are fixed concentric rollers that run on the same raceway The second roller is eccentric and runs on the opposite racewayThe eccentric feature is used to adjust the slider preload in the railFor the 5 roller version the two lateral and the central roller are fixed and run on the same racewayThe second and fourth roller are eccentric and run on the opposite raceway The eccentric feature is used to adjust the slider preload in the rail Because one raceway contacts more rollers than the other raceway the sliders have a preferred loading directionThe slider is marked with two small circular notches indicating the direction with the most rollers and direction of preferred loading Care during assembly is required to ensure the maximum load capacity of the system is achieved

3-ROLLER SLIDER

5-ROLLER SLIDER

The rollers used in the sliders consist of three different geometries to achieve different levels of constraint within the railrsquos raceways

The guiding rollers RCV (concentric) REV (eccentric) are in contact with the raceways by 2 contact-points hereby creating well constrained rollers on the raceway both in radial and axial direction

The Floating Rollers RCP (concentric) REP (eccentric) engage only the peak of the raceway which constrains it radially but allows it to float in the axial direction between the two shoulders The roller can also rotate a little

The Flat full Floating Rollers RCU (concentric) REU (eccentric) engage only the peak of the raceway which constrains it radially but allows it to Float completely free in the axial direction without limitation Being completely cylindrical It allows axial travel to be wider than RP-version but being free from lateral shoulders it can run out of the rail or against the bottom railwhen exceeding the nominal floating capacity The Roller can also rotate a little

THE GUIDING SLIDERS RV

By utilizing all guiding rollers RVRVS sliders are obtained These sliders are completely constrained and will support loads and moments in all directions with the greatest capacity in the radial direction

THE FLOATING SLIDERS RP

By utilizing all floating rollers RPRPS sliders are obtained These sliders are able to carry full radial load while floating and rotating a bit without affecting the preload or the smooth running quality to eliminate eventual binding problems typical for recirculating ball-bearing sliders

THE EXTRA FLOATING RU

By utilizing all full flat floating rollers RU RUS sliders are obtained These sliders are able to carry full radial load while floating and rotating a bit without affecting the preload or the smooth running quality too eliminating eventual binding problems typical for recirculating ball-bearing slidersExtra Floating sliders are used in 2 rail systems to absorb larger parallelism errors in the mounting surfacesBeing completely cylindrical free from lateral shoulders it can run out of the rail or against the bottom rail when exceeding the nominal floating capacity The slider can too rotate a bit

THE ROTATING RA

By mixing guiding and floating rollers RA RAS sliders are obtained These sliders are able to carry full radial load while rotating a bit without affecting the preload or the smooth running quality meanwhile allowing for precise movement These sliders also retain the ability to guide the payload as it travels Rotating sliders are used in 2 rail systems to absorb angular errors in the mounting surfaces that cause traditional bearings to bindNew RAGRAGS sliders with MRG4346 rails offer greater rotation capacity compared with RA sliders with MR43 rails

TECHNICAL FEATURES

The MRG Series Rails are available with two types of mounting holes bull MRG L with counterbored mounting holes for special low head TORX mounting screws that are provided with the rail bull MRG S with countersunk mounting holes for UNI-standard ISO5933 common screws The rail has a ldquoCrdquo shaped cross-section with interior convex raceways The convex raceways are polished for smooth low noise movement The interior raceways are protected from accidental bumps and other damages that might ruin the raceway surface The shape also protects the rollers from similar types of damage MRG Rails are made from high strength steel that is hardened through the innovative TRACE-NOX 20 high depth nitriding process and afterwards with black oxidation that provides an excellent corrosion resistance This treatment is not a plating which can flake off but instead penetrates and alters the material surface The result is a very hard and durable corrosion resistance linear rail that is black in color due to the micro impregnation of oil and antioxidants

MRG 46 RAILS

The new MRG46 rail differs from MRG43 rail as having a thicker C-shaped raceways to provide much greater inertial moment capacity also too withstand loads where the rail is not complely fixed or only fixed for a part (shaft type with ball bushings) eg door fixed to the rail while sliders and the fixed structure so hereby the door flexion is a direct result of the railrsquos innertial moment The load capacity of the relative RG46 and RGS46 sliders are valid with completely fixed rail for its whole length the load capacity may be reduced when the rail is used with self-standing function according to its length not fixed The rail can be supplied without fixing holes or with special hole pitch when used with self-supporting function

LINEAR SELFALIGNMENT SYSTEM WITH MR RAILS AND R RS SLIDERS

The system is based on C-shaped profile with internal raceways and sliders with double row bearings with different numbers and types of rollers according to different load capacities and fixing possibilities

The precision rollers are lubricated for life and with 2RS seals The sliders come in version with 3 or 5 rollers for which some with Eccentric pivot for preload setting The sliders have mounted strong wipers with preoiled felt for good cleaninglubrication of raceways to provide for long maintenance freeoperation

The turning parts are all well protected within the internal raceways and betweenthe wipers to provide the markets most compact and well protected linear rollersystem

The careful finish of the raceways and the build quality of components allow the use of high-speed linear guide up to 10m s with a low noise levelThe self-aligning compositions are illustrated in 14-17 pages

RACEWAY CONTACT OF ROLLERS FOR MR AND MRG RAILS

ROLLER POSITIONING

Sliders are available with either 3 or 5 rollers For the 3 roller version the first and third roller are fixed concentric rollers that run on the same raceway The second roller is eccentric and runs on the opposite racewayThe eccentric feature is used to adjust the slider preload in the railFor the 5 roller version the two lateral and the central roller are fixed and run on the same racewayThe second and fourth roller are eccentric and run on the opposite raceway The eccentric feature is used to adjust the slider preload in the rail Because one raceway contacts more rollers than the other raceway the sliders have a preferred loading directionThe slider is marked with two small circular notches indicating the direction with the most rollers and direction of preferred loading Care during assembly is required to ensure the maximum load capacity of the system is achieved

3-ROLLER SLIDER

5-ROLLER SLIDER

The rollers used in the sliders consist of three different geometries to achieve different levels of constraint within the railrsquos raceways

The guiding rollers RCV (concentric) REV (eccentric) are in contact with the raceways by 2 contact-points hereby creating well constrained rollers on the raceway both in radial and axial direction

The Floating Rollers RCP (concentric) REP (eccentric) engage only the peak of the raceway which constrains it radially but allows it to float in the axial direction between the two shoulders The roller can also rotate a little

The Flat full Floating Rollers RCU (concentric) REU (eccentric) engage only the peak of the raceway which constrains it radially but allows it to Float completely free in the axial direction without limitation Being completely cylindrical It allows axial travel to be wider than RP-version but being free from lateral shoulders it can run out of the rail or against the bottom railwhen exceeding the nominal floating capacity The Roller can also rotate a little

TECHNICAL FEATURES

The MRG Series Rails are available with two types of mounting holes bull MRG L with counterbored mounting holes for special low head TORX mounting screws that are provided with the rail bull MRG S with countersunk mounting holes for UNI-standard ISO5933 common screws The rail has a ldquoCrdquo shaped cross-section with interior convex raceways The convex raceways are polished for smooth low noise movement The interior raceways are protected from accidental bumps and other damages that might ruin the raceway surface The shape also protects the rollers from similar types of damage MRG Rails are made from high strength steel that is hardened through the innovative TRACE-NOX 20 high depth nitriding process and afterwards with black oxidation that provides an excellent corrosion resistance This treatment is not a plating which can flake off but instead penetrates and alters the material surface The result is a very hard and durable corrosion resistance linear rail that is black in color due to the micro impregnation of oil and antioxidants

The new MRG46 rail differs from MRG43 rail as having a thicker C-shaped raceways to provide much greater inertial moment capacity also too withstand loads where the rail is not complely fixed or only fixed for a part (shaft type with ball bushings) eg door fixed to the rail while sliders and the fixed structure so hereby the door flexion is a direct result of the railrsquos innertial moment The load capacity of the relative RG46 and RGS46 sliders are valid with completely fixed rail for its whole length the load capacity may be reduced when the rail is used with self-standing function according to its length not fixed The rail can be supplied without fixing holes or with special hole pitch when used with self-supporting function

LINEAR SELFALIGNMENT SYSTEM WITH MR RAILS AND R RS SLIDERS

The system is based on C-shaped profile with internal raceways and sliders with double row bearings with different numbers and types of rollers according to different load capacities and fixing possibilities

The precision rollers are lubricated for life and with 2RS seals The sliders come in version with 3 or 5 rollers for which some with Eccentric pivot for preload setting The sliders have mounted strong wipers with preoiled felt for good cleaninglubrication of raceways to provide for long maintenance freeoperation

The turning parts are all well protected within the internal raceways and betweenthe wipers to provide the markets most compact and well protected linear rollersystem

The careful finish of the raceways and the build quality of components allow the use of high-speed linear guide up to 10m s with a low noise levelThe self-aligning compositions are illustrated in 14-17 pages

TECHNICAL FEATURES

The MR Series Rails are available with two types of mounting holes bull MR L with counterbored mounting holes for special low head TORX mounting screws that are provided with the rail bull MR S with countersunk mounting holes for UNI-standard ISO5933 common screws The rail has a ldquoCrdquo shaped cross-section with interior convex raceways The convex raceways are polished for smooth low noise movement The interior raceways are protected from accidental bumps and other damage that might ruin the raceway surface The shape also protects the rollers from similar types of damage MR Rails are made from high strength steel that is hardened through the innovative TRACE-NOX 10 high depth nitride hardening process and with an afterwards black oxidation that provides an excellent corrosion resistance This treatment is not a plating which can flake off but instead penetrates and al-ters the material surface The result is a very hard and durable corrosion resistance linear rail that is black in color due to the micro impregnation of oil and antioxidants

RACEWAY CONTACT OF ROLLERS FOR MR AND MRG RAILS

ROLLER POSITIONING

Sliders are available with either 3 or 5 rollers For the 3 roller version the first and third roller are fixed concentric rollers that run on the same raceway The second roller is eccentric and runs on the opposite racewayThe eccentric feature is used to adjust the slider preload in the railFor the 5 roller version the two lateral and the central roller are fixed and run on the same racewayThe second and fourth roller are eccentric and run on the opposite raceway The eccentric feature is used to adjust the slider preload in the rail Because one raceway contacts more rollers than the other raceway the sliders have a preferred loading directionThe slider is marked with two small circular notches indicating the direction with the most rollers and direction of preferred loading Care during assembly is required to ensure the maximum load capacity of the system is achieved

3-ROLLER SLIDER

5-ROLLER SLIDER

The rollers used in the sliders consist of three different geometries to achieve different levels of constraint within the railrsquos raceways

The guiding rollers RCV (concentric) REV (eccentric) are in contact with the raceways by 2 contact-points hereby creating well constrained rollers on the raceway both in radial and axial direction

The Floating Rollers RCP (concentric) REP (eccentric) engage only the peak of the raceway which constrains it radially but allows it to float in the axial direction between the two shoulders The roller can also rotate a little

The Flat full Floating Rollers RCU (concentric) REU (eccentric) engage only the peak of the raceway which constrains it radially but allows it to Float completely free in the axial direction without limitation Being completely cylindrical It allows axial travel to be wider than RP-version but being free from lateral shoulders it can run out of the rail or against the bottom railwhen exceeding the nominal floating capacity The Roller can also rotate a little

COMPOSITION SLIDERS SERIES R and RG

THE GUIDING SLIDERS RV

By utilizing all guiding rollers RVRVS sliders are obtained These sliders are completely constrained and will support loads and moments in all directions with the greatest capacity in the radial direction

THE FLOATING SLIDERS RP

By utilizing all floating rollers RPRPS sliders are obtained These sliders are able to carry full radial load while floating and rotating a bit without affecting the preload or the smooth running quality to eliminate eventual binding problems typical for recirculating ball-bearing sliders

THE EXTRA FLOATING RU

By utilizing all full flat floating rollers RU RUS sliders are obtained These sliders are able to carry full radial load while floating and rotating a bit without affecting the preload or the smooth running quality too eliminating eventual binding problems typical for recirculating ball-bearing slidersExtra Floating sliders are used in 2 rail systems to absorb larger parallelism errors in the mounting surfacesBeing completely cylindrical free from lateral shoulders it can run out of the rail or against the bottom rail when exceeding the nominal floating capacity The slider can too rotate a bit

THE ROTATING RA

By mixing guiding and floating rollers RA RAS sliders are obtained These sliders are able to carry full radial load while rotating a bit without affecting the preload or the smooth running quality meanwhile allowing for precise movement These sliders also retain the ability to guide the payload as it travels Rotating sliders are used in 2 rail systems to absorb angular errors in the mounting surfaces that cause traditional bearings to bindNew RAGRAGS sliders with MRG4346 rails offer greater rotation capacity compared with RA sliders with MR43 rails

TECHNICAL FEATURES

The MRG Series Rails are available with two types of mounting holes bull MRG L with counterbored mounting holes for special low head TORX mounting screws that are provided with the rail bull MRG S with countersunk mounting holes for UNI-standard ISO5933 common screws The rail has a ldquoCrdquo shaped cross-section with interior convex raceways The convex raceways are polished for smooth low noise movement The interior raceways are protected from accidental bumps and other damages that might ruin the raceway surface The shape also protects the rollers from similar types of damage MRG Rails are made from high strength steel that is hardened through the innovative TRACE-NOX 20 high depth nitriding process and afterwards with black oxidation that provides an excellent corrosion resistance This treatment is not a plating which can flake off but instead penetrates and alters the material surface The result is a very hard and durable corrosion resistance linear rail that is black in color due to the micro impregnation of oil and antioxidants

LINEAR SELFALIGNMENT SYSTEM WITH MR RAILS AND R RS SLIDERS

The system is based on C-shaped profile with internal raceways and sliders with double row bearings with different numbers and types of rollers according to different load capacities and fixing possibilities

The precision rollers are lubricated for life and with 2RS seals The sliders come in version with 3 or 5 rollers for which some with Eccentric pivot for preload setting The sliders have mounted strong wipers with preoiled felt for good cleaninglubrication of raceways to provide for long maintenance freeoperation

The turning parts are all well protected within the internal raceways and betweenthe wipers to provide the markets most compact and well protected linear rollersystem

The careful finish of the raceways and the build quality of components allow the use of high-speed linear guide up to 10m s with a low noise levelThe self-aligning compositions are illustrated in 14-17 pages

TECHNICAL FEATURES

The MR Series Rails are available with two types of mounting holes bull MR L with counterbored mounting holes for special low head TORX mounting screws that are provided with the rail bull MR S with countersunk mounting holes for UNI-standard ISO5933 common screws The rail has a ldquoCrdquo shaped cross-section with interior convex raceways The convex raceways are polished for smooth low noise movement The interior raceways are protected from accidental bumps and other damage that might ruin the raceway surface The shape also protects the rollers from similar types of damage MR Rails are made from high strength steel that is hardened through the innovative TRACE-NOX 10 high depth nitride hardening process and with an afterwards black oxidation that provides an excellent corrosion resistance This treatment is not a plating which can flake off but instead penetrates and al-ters the material surface The result is a very hard and durable corrosion resistance linear rail that is black in color due to the micro impregnation of oil and antioxidants

RACEWAY CONTACT OF ROLLERS FOR MR AND MRG RAILS

ROLLER POSITIONING

Sliders are available with either 3 or 5 rollers For the 3 roller version the first and third roller are fixed concentric rollers that run on the same raceway The second roller is eccentric and runs on the opposite racewayThe eccentric feature is used to adjust the slider preload in the railFor the 5 roller version the two lateral and the central roller are fixed and run on the same racewayThe second and fourth roller are eccentric and run on the opposite raceway The eccentric feature is used to adjust the slider preload in the rail Because one raceway contacts more rollers than the other raceway the sliders have a preferred loading directionThe slider is marked with two small circular notches indicating the direction with the most rollers and direction of preferred loading Care during assembly is required to ensure the maximum load capacity of the system is achieved

3-ROLLER SLIDER

5-ROLLER SLIDER

The rollers used in the sliders consist of three different geometries to achieve different levels of constraint within the railrsquos raceways

The guiding rollers RCV (concentric) REV (eccentric) are in contact with the raceways by 2 contact-points hereby creating well constrained rollers on the raceway both in radial and axial direction

The Floating Rollers RCP (concentric) REP (eccentric) engage only the peak of the raceway which constrains it radially but allows it to float in the axial direction between the two shoulders The roller can also rotate a little

The Flat full Floating Rollers RCU (concentric) REU (eccentric) engage only the peak of the raceway which constrains it radially but allows it to Float completely free in the axial direction without limitation Being completely cylindrical It allows axial travel to be wider than RP-version but being free from lateral shoulders it can run out of the rail or against the bottom railwhen exceeding the nominal floating capacity The Roller can also rotate a little

THE GUIDING SLIDERS RV

By utilizing all guiding rollers RVRVS sliders are obtained These sliders are completely constrained and will support loads and moments in all directions with the greatest capacity in the radial direction

THE FLOATING SLIDERS RP

By utilizing all floating rollers RPRPS sliders are obtained These sliders are able to carry full radial load while floating and rotating a bit without affecting the preload or the smooth running quality to eliminate eventual binding problems typical for recirculating ball-bearing sliders

THE EXTRA FLOATING RU

By utilizing all full flat floating rollers RU RUS sliders are obtained These sliders are able to carry full radial load while floating and rotating a bit without affecting the preload or the smooth running quality too eliminating eventual binding problems typical for recirculating ball-bearing slidersExtra Floating sliders are used in 2 rail systems to absorb larger parallelism errors in the mounting surfacesBeing completely cylindrical free from lateral shoulders it can run out of the rail or against the bottom rail when exceeding the nominal floating capacity The slider can too rotate a bit

THE ROTATING RA

By mixing guiding and floating rollers RA RAS sliders are obtained These sliders are able to carry full radial load while rotating a bit without affecting the preload or the smooth running quality meanwhile allowing for precise movement These sliders also retain the ability to guide the payload as it travels Rotating sliders are used in 2 rail systems to absorb angular errors in the mounting surfaces that cause traditional bearings to bindNew RAGRAGS sliders with MRG4346 rails offer greater rotation capacity compared with RA sliders with MR43 rails

TECHNICAL FEATURES

The MRG Series Rails are available with two types of mounting holes bull MRG L with counterbored mounting holes for special low head TORX mounting screws that are provided with the rail bull MRG S with countersunk mounting holes for UNI-standard ISO5933 common screws The rail has a ldquoCrdquo shaped cross-section with interior convex raceways The convex raceways are polished for smooth low noise movement The interior raceways are protected from accidental bumps and other damages that might ruin the raceway surface The shape also protects the rollers from similar types of damage MRG Rails are made from high strength steel that is hardened through the innovative TRACE-NOX 20 high depth nitriding process and afterwards with black oxidation that provides an excellent corrosion resistance This treatment is not a plating which can flake off but instead penetrates and alters the material surface The result is a very hard and durable corrosion resistance linear rail that is black in color due to the micro impregnation of oil and antioxidants

MRG 46 RAILS

The new MRG46 rail differs from MRG43 rail as having a thicker C-shaped raceways to provide much greater inertial moment capacity also too withstand loads where the rail is not complely fixed or only fixed for a part (shaft type with ball bushings) eg door fixed to the rail while sliders and the fixed structure so hereby the door flexion is a direct result of the railrsquos innertial moment The load capacity of the relative RG46 and RGS46 sliders are valid with completely fixed rail for its whole length the load capacity may be reduced when the rail is used with self-standing function according to its length not fixed The rail can be supplied without fixing holes or with special hole pitch when used with self-supporting function

LINEAR SELFALIGNMENT SYSTEM WITH MR RAILS AND R RS SLIDERS

The system is based on C-shaped profile with internal raceways and sliders with double row bearings with different numbers and types of rollers according to different load capacities and fixing possibilities

The precision rollers are lubricated for life and with 2RS seals The sliders come in version with 3 or 5 rollers for which some with Eccentric pivot for preload setting The sliders have mounted strong wipers with preoiled felt for good cleaninglubrication of raceways to provide for long maintenance freeoperation

The turning parts are all well protected within the internal raceways and betweenthe wipers to provide the markets most compact and well protected linear rollersystem

The careful finish of the raceways and the build quality of components allow the use of high-speed linear guide up to 10m s with a low noise levelThe self-aligning compositions are illustrated in 14-17 pages

COMPOSITION SLIDERS SERIES R and RG

THE GUIDING SLIDERS RV

By utilizing all guiding rollers RVRVS sliders are obtained These sliders are completely constrained and will support loads and moments in all directions with the greatest capacity in the radial direction

THE FLOATING SLIDERS RP

By utilizing all floating rollers RPRPS sliders are obtained These sliders are able to carry full radial load while floating and rotating a bit without affecting the preload or the smooth running quality to eliminate eventual binding problems typical for recirculating ball-bearing sliders

THE EXTRA FLOATING RU

By utilizing all full flat floating rollers RU RUS sliders are obtained These sliders are able to carry full radial load while floating and rotating a bit without affecting the preload or the smooth running quality too eliminating eventual binding problems typical for recirculating ball-bearing slidersExtra Floating sliders are used in 2 rail systems to absorb larger parallelism errors in the mounting surfacesBeing completely cylindrical free from lateral shoulders it can run out of the rail or against the bottom rail when exceeding the nominal floating capacity The slider can too rotate a bit

THE ROTATING RA

By mixing guiding and floating rollers RA RAS sliders are obtained These sliders are able to carry full radial load while rotating a bit without affecting the preload or the smooth running quality meanwhile allowing for precise movement These sliders also retain the ability to guide the payload as it travels Rotating sliders are used in 2 rail systems to absorb angular errors in the mounting surfaces that cause traditional bearings to bindNew RAGRAGS sliders with MRG4346 rails offer greater rotation capacity compared with RA sliders with MR43 rails

TECHNICAL FEATURES

The MRG Series Rails are available with two types of mounting holes bull MRG L with counterbored mounting holes for special low head TORX mounting screws that are provided with the rail bull MRG S with countersunk mounting holes for UNI-standard ISO5933 common screws The rail has a ldquoCrdquo shaped cross-section with interior convex raceways The convex raceways are polished for smooth low noise movement The interior raceways are protected from accidental bumps and other damages that might ruin the raceway surface The shape also protects the rollers from similar types of damage MRG Rails are made from high strength steel that is hardened through the innovative TRACE-NOX 20 high depth nitriding process and afterwards with black oxidation that provides an excellent corrosion resistance This treatment is not a plating which can flake off but instead penetrates and alters the material surface The result is a very hard and durable corrosion resistance linear rail that is black in color due to the micro impregnation of oil and antioxidants

LINEAR SELFALIGNMENT SYSTEM WITH MR RAILS AND R RS SLIDERS

The system is based on C-shaped profile with internal raceways and sliders with double row bearings with different numbers and types of rollers according to different load capacities and fixing possibilities

The precision rollers are lubricated for life and with 2RS seals The sliders come in version with 3 or 5 rollers for which some with Eccentric pivot for preload setting The sliders have mounted strong wipers with preoiled felt for good cleaninglubrication of raceways to provide for long maintenance freeoperation

The turning parts are all well protected within the internal raceways and betweenthe wipers to provide the markets most compact and well protected linear rollersystem

The careful finish of the raceways and the build quality of components allow the use of high-speed linear guide up to 10m s with a low noise levelThe self-aligning compositions are illustrated in 14-17 pages

TECHNICAL FEATURES

The MR Series Rails are available with two types of mounting holes bull MR L with counterbored mounting holes for special low head TORX mounting screws that are provided with the rail bull MR S with countersunk mounting holes for UNI-standard ISO5933 common screws The rail has a ldquoCrdquo shaped cross-section with interior convex raceways The convex raceways are polished for smooth low noise movement The interior raceways are protected from accidental bumps and other damage that might ruin the raceway surface The shape also protects the rollers from similar types of damage MR Rails are made from high strength steel that is hardened through the innovative TRACE-NOX 10 high depth nitride hardening process and with an afterwards black oxidation that provides an excellent corrosion resistance This treatment is not a plating which can flake off but instead penetrates and al-ters the material surface The result is a very hard and durable corrosion resistance linear rail that is black in color due to the micro impregnation of oil and antioxidants

TECHNICAL FEATURES

The MRG Series Rails are available with two types of mounting holes bull MRG L with counterbored mounting holes for special low head TORX mounting screws that are provided with the rail bull MRG S with countersunk mounting holes for UNI-standard ISO5933 common screws The rail has a ldquoCrdquo shaped cross-section with interior convex raceways The convex raceways are polished for smooth low noise movement The interior raceways are protected from accidental bumps and other damages that might ruin the raceway surface The shape also protects the rollers from similar types of damage MRG Rails are made from high strength steel that is hardened through the innovative TRACE-NOX 20 high depth nitriding process and afterwards with black oxidation that provides an excellent corrosion resistance This treatment is not a plating which can flake off but instead penetrates and alters the material surface The result is a very hard and durable corrosion resistance linear rail that is black in color due to the micro impregnation of oil and antioxidants

MRG 46 RAILS

The new MRG46 rail differs from MRG43 rail as having a thicker C-shaped raceways to provide much greater inertial moment capacity also too withstand loads where the rail is not complely fixed or only fixed for a part (shaft type with ball bushings) eg door fixed to the rail while sliders and the fixed structure so hereby the door flexion is a direct result of the railrsquos innertial moment The load capacity of the relative RG46 and RGS46 sliders are valid with completely fixed rail for its whole length the load capacity may be reduced when the rail is used with self-standing function according to its length not fixed The rail can be supplied without fixing holes or with special hole pitch when used with self-supporting function

LINEAR SELFALIGNMENT SYSTEM WITH MR RAILS AND R RS SLIDERS

The system is based on C-shaped profile with internal raceways and sliders with double row bearings with different numbers and types of rollers according to different load capacities and fixing possibilities

The precision rollers are lubricated for life and with 2RS seals The sliders come in version with 3 or 5 rollers for which some with Eccentric pivot for preload setting The sliders have mounted strong wipers with preoiled felt for good cleaninglubrication of raceways to provide for long maintenance freeoperation

The turning parts are all well protected within the internal raceways and betweenthe wipers to provide the markets most compact and well protected linear rollersystem

The careful finish of the raceways and the build quality of components allow the use of high-speed linear guide up to 10m s with a low noise levelThe self-aligning compositions are illustrated in 14-17 pages

TECHNICAL FEATURES

The MRG Series Rails are available with two types of mounting holes bull MRG L with counterbored mounting holes for special low head TORX mounting screws that are provided with the rail bull MRG S with countersunk mounting holes for UNI-standard ISO5933 common screws The rail has a ldquoCrdquo shaped cross-section with interior convex raceways The convex raceways are polished for smooth low noise movement The interior raceways are protected from accidental bumps and other damages that might ruin the raceway surface The shape also protects the rollers from similar types of damage MRG Rails are made from high strength steel that is hardened through the innovative TRACE-NOX 20 high depth nitriding process and afterwards with black oxidation that provides an excellent corrosion resistance This treatment is not a plating which can flake off but instead penetrates and alters the material surface The result is a very hard and durable corrosion resistance linear rail that is black in color due to the micro impregnation of oil and antioxidants

SPECIAL SCREWS FOR FIXING OF MRGL RAILS SUPPLIED WITH THE RAILS(2) THE GUIDES ARE PROVIDED WITH COUNTERBORED HOLES WITHOUT THE PROTECTIVE TREATMENT

MRG 46 RAILS

The new MRG46 rail differs from MRG43 rail as having a thicker C-shaped raceways to provide much greater inertial moment capacity also too withstand loads where the rail is not complely fixed or only fixed for a part (shaft type with ball bushings) eg door fixed to the rail while sliders and the fixed structure so hereby the door flexion is a direct result of the railrsquos innertial moment The load capacity of the relative RG46 and RGS46 sliders are valid with completely fixed rail for its whole length the load capacity may be reduced when the rail is used with self-standing function according to its length not fixed The rail can be supplied without fixing holes or with special hole pitch when used with self-supporting function

LINEAR SELFALIGNMENT SYSTEM WITH MR RAILS AND R RS SLIDERS

The system is based on C-shaped profile with internal raceways and sliders with double row bearings with different numbers and types of rollers according to different load capacities and fixing possibilities

The precision rollers are lubricated for life and with 2RS seals The sliders come in version with 3 or 5 rollers for which some with Eccentric pivot for preload setting The sliders have mounted strong wipers with preoiled felt for good cleaninglubrication of raceways to provide for long maintenance freeoperation

The turning parts are all well protected within the internal raceways and betweenthe wipers to provide the markets most compact and well protected linear rollersystem

The careful finish of the raceways and the build quality of components allow the use of high-speed linear guide up to 10m s with a low noise levelThe self-aligning compositions are illustrated in 14-17 pages

MRG 46 RAILS

The new MRG46 rail differs from MRG43 rail as having a thicker C-shaped raceways to provide much greater inertial moment capacity also too withstand loads where the rail is not complely fixed or only fixed for a part (shaft type with ball bushings) eg door fixed to the rail while sliders and the fixed structure so hereby the door flexion is a direct result of the railrsquos innertial moment The load capacity of the relative RG46 and RGS46 sliders are valid with completely fixed rail for its whole length the load capacity may be reduced when the rail is used with self-standing function according to its length not fixed The rail can be supplied without fixing holes or with special hole pitch when used with self-supporting function

LINEAR SELFALIGNMENT SYSTEM WITH MR RAILS AND R RS SLIDERS

The system is based on C-shaped profile with internal raceways and sliders with double row bearings with different numbers and types of rollers according to different load capacities and fixing possibilities

The precision rollers are lubricated for life and with 2RS seals The sliders come in version with 3 or 5 rollers for which some with Eccentric pivot for preload setting The sliders have mounted strong wipers with preoiled felt for good cleaninglubrication of raceways to provide for long maintenance freeoperation

The turning parts are all well protected within the internal raceways and betweenthe wipers to provide the markets most compact and well protected linear rollersystem

The careful finish of the raceways and the build quality of components allow the use of high-speed linear guide up to 10m s with a low noise levelThe self-aligning compositions are illustrated in 14-17 pages

TECHNICAL FEATURES

The MR Series Rails are available with two types of mounting holes bull MR L with counterbored mounting holes for special low head TORX mounting screws that are provided with the rail bull MR S with countersunk mounting holes for UNI-standard ISO5933 common screws The rail has a ldquoCrdquo shaped cross-section with interior convex raceways The convex raceways are polished for smooth low noise movement The interior raceways are protected from accidental bumps and other damage that might ruin the raceway surface The shape also protects the rollers from similar types of damage MR Rails are made from high strength steel that is hardened through the innovative TRACE-NOX 10 high depth nitride hardening process and with an afterwards black oxidation that provides an excellent corrosion resistance This treatment is not a plating which can flake off but instead penetrates and al-ters the material surface The result is a very hard and durable corrosion resistance linear rail that is black in color due to the micro impregnation of oil and antioxidants

MRG 46 RAILS

The new MRG46 rail differs from MRG43 rail as having a thicker C-shaped raceways to provide much greater inertial moment capacity also too withstand loads where the rail is not complely fixed or only fixed for a part (shaft type with ball bushings) eg door fixed to the rail while sliders and the fixed structure so hereby the door flexion is a direct result of the railrsquos innertial moment The load capacity of the relative RG46 and RGS46 sliders are valid with completely fixed rail for its whole length the load capacity may be reduced when the rail is used with self-standing function according to its length not fixed The rail can be supplied without fixing holes or with special hole pitch when used with self-supporting function

LINEAR SELFALIGNMENT SYSTEM WITH MR RAILS AND R RS SLIDERS

The system is based on C-shaped profile with internal raceways and sliders with double row bearings with different numbers and types of rollers according to different load capacities and fixing possibilities

The precision rollers are lubricated for life and with 2RS seals The sliders come in version with 3 or 5 rollers for which some with Eccentric pivot for preload setting The sliders have mounted strong wipers with preoiled felt for good cleaninglubrication of raceways to provide for long maintenance freeoperation

The turning parts are all well protected within the internal raceways and betweenthe wipers to provide the markets most compact and well protected linear rollersystem

The careful finish of the raceways and the build quality of components allow the use of high-speed linear guide up to 10m s with a low noise levelThe self-aligning compositions are illustrated in 14-17 pages

TECHNICAL FEATURES

The MR Series Rails are available with two types of mounting holes bull MR L with counterbored mounting holes for special low head TORX mounting screws that are provided with the rail bull MR S with countersunk mounting holes for UNI-standard ISO5933 common screws The rail has a ldquoCrdquo shaped cross-section with interior convex raceways The convex raceways are polished for smooth low noise movement The interior raceways are protected from accidental bumps and other damage that might ruin the raceway surface The shape also protects the rollers from similar types of damage MR Rails are made from high strength steel that is hardened through the innovative TRACE-NOX 10 high depth nitride hardening process and with an afterwards black oxidation that provides an excellent corrosion resistance This treatment is not a plating which can flake off but instead penetrates and al-ters the material surface The result is a very hard and durable corrosion resistance linear rail that is black in color due to the micro impregnation of oil and antioxidants

LINEAR SELFALIGNMENT SYSTEM WITH MR RAILS AND R RS SLIDERS

The system is based on C-shaped profile with internal raceways and sliders with double row bearings with different numbers and types of rollers according to different load capacities and fixing possibilities

The precision rollers are lubricated for life and with 2RS seals The sliders come in version with 3 or 5 rollers for which some with Eccentric pivot for preload setting The sliders have mounted strong wipers with preoiled felt for good cleaninglubrication of raceways to provide for long maintenance freeoperation

The turning parts are all well protected within the internal raceways and betweenthe wipers to provide the markets most compact and well protected linear rollersystem

The careful finish of the raceways and the build quality of components allow the use of high-speed linear guide up to 10m s with a low noise levelThe self-aligning compositions are illustrated in 14-17 pages

TECHNICAL FEATURES

The MR Series Rails are available with two types of mounting holes bull MR L with counterbored mounting holes for special low head TORX mounting screws that are provided with the rail bull MR S with countersunk mounting holes for UNI-standard ISO5933 common screws The rail has a ldquoCrdquo shaped cross-section with interior convex raceways The convex raceways are polished for smooth low noise movement The interior raceways are protected from accidental bumps and other damage that might ruin the raceway surface The shape also protects the rollers from similar types of damage MR Rails are made from high strength steel that is hardened through the innovative TRACE-NOX 10 high depth nitride hardening process and with an afterwards black oxidation that provides an excellent corrosion resistance This treatment is not a plating which can flake off but instead penetrates and al-ters the material surface The result is a very hard and durable corrosion resistance linear rail that is black in color due to the micro impregnation of oil and antioxidants

LINEAR SELFALIGNMENT SYSTEM WITH MR RAILS AND R RS SLIDERS

The system is based on C-shaped profile with internal raceways and sliders with double row bearings with different numbers and types of rollers according to different load capacities and fixing possibilities

The precision rollers are lubricated for life and with 2RS seals The sliders come in version with 3 or 5 rollers for which some with Eccentric pivot for preload setting The sliders have mounted strong wipers with preoiled felt for good cleaninglubrication of raceways to provide for long maintenance freeoperation

The turning parts are all well protected within the internal raceways and betweenthe wipers to provide the markets most compact and well protected linear rollersystem

The careful finish of the raceways and the build quality of components allow the use of high-speed linear guide up to 10m s with a low noise levelThe self-aligning compositions are illustrated in 14-17 pages

TECHNICAL FEATURES

The MR Series Rails are available with two types of mounting holes bull MR L with counterbored mounting holes for special low head TORX mounting screws that are provided with the rail bull MR S with countersunk mounting holes for UNI-standard ISO5933 common screws The rail has a ldquoCrdquo shaped cross-section with interior convex raceways The convex raceways are polished for smooth low noise movement The interior raceways are protected from accidental bumps and other damage that might ruin the raceway surface The shape also protects the rollers from similar types of damage MR Rails are made from high strength steel that is hardened through the innovative TRACE-NOX 10 high depth nitride hardening process and with an afterwards black oxidation that provides an excellent corrosion resistance This treatment is not a plating which can flake off but instead penetrates and al-ters the material surface The result is a very hard and durable corrosion resistance linear rail that is black in color due to the micro impregnation of oil and antioxidants

TECHNICAL FEATURES

The MR Series Rails are available with two types of mounting holes bull MR L with counterbored mounting holes for special low head TORX mounting screws that are provided with the rail bull MR S with countersunk mounting holes for UNI-standard ISO5933 common screws The rail has a ldquoCrdquo shaped cross-section with interior convex raceways The convex raceways are polished for smooth low noise movement The interior raceways are protected from accidental bumps and other damage that might ruin the raceway surface The shape also protects the rollers from similar types of damage MR Rails are made from high strength steel that is hardened through the innovative TRACE-NOX 10 high depth nitride hardening process and with an afterwards black oxidation that provides an excellent corrosion resistance This treatment is not a plating which can flake off but instead penetrates and al-ters the material surface The result is a very hard and durable corrosion resistance linear rail that is black in color due to the micro impregnation of oil and antioxidants

TECHNICAL FEATURES

The MR Series Rails are available with two types of mounting holes bull MR L with counterbored mounting holes for special low head TORX mounting screws that are provided with the rail bull MR S with countersunk mounting holes for UNI-standard ISO5933 common screws The rail has a ldquoCrdquo shaped cross-section with interior convex raceways The convex raceways are polished for smooth low noise movement The interior raceways are protected from accidental bumps and other damage that might ruin the raceway surface The shape also protects the rollers from similar types of damage MR Rails are made from high strength steel that is hardened through the innovative TRACE-NOX 10 high depth nitride hardening process and with an afterwards black oxidation that provides an excellent corrosion resistance This treatment is not a plating which can flake off but instead penetrates and al-ters the material surface The result is a very hard and durable corrosion resistance linear rail that is black in color due to the micro impregnation of oil and antioxidants
