There are many antifriction bearings ... ....but the Franke bearing is unique

...either bearing elements1. They sustain forces from whatever direction due to their 4-point geometry

The rolling elements run on four race rings from spring steel or non-corrosive steel.Open race rings have the advantage that they fit themselves tightly intothe bearing rings of the mating structure and compensate machiningtolerances. With this technology high precision even with large bearingdiameters is achieved.

2. Ground or drawn race rings for easy run and higheconomical efficiency

Franke developed a special grinding method for the race rings aimed atproducing defined race ways which are perfectly adapted to the balldiameter and the planned application. This way the balls are optimallyguided, the load rating is increased and the running behaviour is improved.

Depending on the case of application the race rings are supplied inparticular surface qualities. Thus the load, the capacity, and precision ofthe bearing elements are increased and they are better adapted toparticular demands.

3. Ball cage with retained balls for maximum precision withvery low frictional resistance

The ball cage with retained balls keeps the rolling elements in theirdefined position and facilitates mounting. This way friction is reduced thusimproving the running behaviour and reducing the lubricant consumptionof the bearing.This cage type, the so-called ball chain, has been successfully used formany years with bearing assemblies and re-circulating ball elements.

...or complete bearing assemblies4. Shape and material of the enclosing structure can be freelychosen

Franke bearing assemblies are ready-to-be installed complete bearingswith integrated bearing elements. The outer geometrical dimensions areadapted to your requirements hence tolerances and cost of your designare reduced.

5. Many different types make the individual adaptation to aspecial application possible

Bearing assemblies are available in manifold variants. Owing to years ofexperience we are able to produce custom-made special bearings whichare adapted to any specific application.

Our preferential series LDV provides the cheapest and fastest solution formany applications.

Machine buildingFranke bearing elements are veritable small space wonders. Theyadapt themselves even to the most limited space conditions andallow you a high degree of freedom in the design of the enclosingstructure.We plan the optimum bearing arrangement for your machine partsdepending on your load and speed indications. Herewith the preciseadaptation of the cross section, the osculation, or the angularposition of the race ways are the decisive parameters for longevityand safe functioning.

Franke bearing elements are proven components in circular indexingtables.

Medical technologyFranke CT bearings are suited for very high speeds of revolution andcan be re-adjusted without clearance even after a long period ofoperation.Extreme running silence is reached by the fact that the componentsrest in an elastomer envelope. The elastomer reduces the bearingnoise and provides the electrical insulation of the housing parts.Specific features of theses bearings are uniform run, low rotationalresistance, and low structure-borne noise.You have the choice between many different series which can beadapted to your specific wishes. The design including cross section,bearing seat, drilling configuration can be freely chosen. Adaptationis possible even to the degree that we supply complete modules.

More than 10.000 Franke bearing assemblies of series SDS are inpractical service worldwide.

Textile machinesFranke bearing elements are compact, sturdy and have a long life.Therefore they are ideally suited for the use in textile machines. Theirhigh economical efficiency has convinced designers of all branches.The race rings are inserted directly into the enclosing structure.There is the choice between rings from spring steel, con-corrosivesteel, or antimagnetic steel.Until now more than 100.000 knitting machines worldwide have beenequipped with Franke bearings.

Food industry / packaging industryThe fact that there are numerous variants of Franke bearings whosematerials can be freely chosen makes them also suitable for thespecial requirements of the food and packaging technology. Here weoffer washable components from non-corrosive steel or aluminium,or components which are suited for special lubricants, or for lubricant-free applications. Maintenance and cleaning of Franke bearings arefacilitated by easy dismantling. Their longevity makes themeconomically very efficient.

Clean roomFranke antifriction bearings are ideally suited for particular applicationssuch as under clean room, high temperature, or vacuum conditions.Even the most demanding requirements can be met by the use ofspecial materials like ceramics or Teflon. The design and the matingdimensions can be individually planned. Types with very low rotationalresistance or lubricant-free versions are possible. There are almostno limits in the realisation of your motive needs.

Particular requirements ... ...need particular designs ...

1. Franke 4-point contact bearing assembly with acarrying angle of 45°

The race ways are arranged with an angle of 45° thus enabling an optimum carryingcapacity for loads from whatever direction. The bearings are adjusted without clearance;the rotational resistance is adapted to their application. The material for the enclosingstructure can be freely chosen and has no influence on the load rating (steel, aluminiumnon-corrosive steel, bronze casting, plastic).

There are numerous variants of seals as for instance the labyrinth seal which is shownin the picture. We find out the appropriate variant for your special application.

2. Franke 4-point contact bearing assembly with a carrying angle of 30°for radial loads

A traditional 4-point contact bearing assembly can be transformed to a radial/axialbearing by adapting its carrying angle. The bearing features can be suited to yourindividual needs.The inserted race rings from spring steel provide a high carrying capacity which isindependent from whether the mating structure is made of aluminium or any othermaterial.

Very high stiffness is obtained by adjustment of the corresponding preload. The bearingruns without clearance even with relatively high loads. There are different kinds oftoothing: e.g. spur toothing, helical gearing, worm gearing, toothed belt.

3. Franke double row inclined bearings for high rotational speed and veryhigh precision

Double row inclined bearings combine the carrying capacity for loads from whateverdirection with the running silence and precision which are typical for axial or radialbearings.The defined rolling motion of both ball rows provides low friction and consequently anespecially easy and silent run.Numerous design variants have been realised, e.g. a particularly compact bearing forbaggage scanning devices, which rotates at very high RPMs and at a circumferentialspeed of 16m/s.Material combinations as e.g. an outer ring from steel and an inner ring from aluminiumare possible. Adjustment and re-adjustment is made by means of a threaded ring.

4. Franke double row 3-point contact bearing with 3 race rings

Double row 3-point contact bearings are flexible bearings with low rotational resistanceand a very good running behaviour. The bearing compensates elastic tension anddeformation without any negative influence on the bearing function.These bearings are recommended for applications where the mating structures andoperating conditions produce relatively high torsion.

They all are called antifriction bearings butthere is a difference

... and they are all-rounders

5. Franke 3-point contact bearing as movable bearingwith 3 race rings

This type is optimally suited for the realisation of a movablebearing and has similar features as a 4-point contact bearing.Even the most demanding requirements can be met by itscombination with a 4-point contact bearing.

6. Franke 4-point contact bearing with seal

There are many possibilities to seal Franke bearing assem-blies. Sealing by an O-ring as it is shown in the picture is as wellpossible as a lip seal or a labyrinth seal.

Franke bearing assemblies are complete structural units andare dimensioned according to your design. Herewith machiningtolerances are reduced and mounting is simplified.

7. Franke double bearings for particular applications

Each ring can be moved individually and be turned in differentdirections. The number of rings is not limited and the structuralshape can be individually adapted.

Double bearings are one example in many others showing theway how custom-designed bearings provide structuraladvantages for the user.

8. Franke bearing assemblies as cylindrical rollerbearings

Cylindrical roller bearings are unrivalled regarding stiffnessand compactness. Here the positive effect of the integratedFranke system with the inserted race rings is obvious.



Bearing assemblies of the low noise type and double rowangular bearings are bearings which are ready for installa-tion meeting even the highest requirements concerningeasy run, low noise and precision.In the last few years we have supplied more than 5000central bearings for computer tomographs worldwide. Allthe famous manufacturers from this branch have realizedthe advantages of the Franke system and are using themconsequently.

Here we can give you only a short survey on the differentbearing types. The application possibilities are too versati-le, the desires are too different.

All dimensions (height, width, bore configuration, etc.) aredetermined according to the customer’s desires and requi-rements. We produce antifriction bearings of these types inthe diameters from 500 - 1600 mm.

The elastomer is used in the stationary ring.The inner ringis electrically insulated against the outer ring.

We supply all data according to specification. RPMs, radialand axial accuracy as well as airborne and structure-bornenoise can be documented and supplied with each bearing.

On request our bearings are tested in longtime run, herestiffness against tilt and lifetime are investigated.

In addition we make detailed calculations.

Please benefit from our 50 years of experience in theproduction of antifriction bearings.

Angular ball bearingSeries LDS

Especially for small mounting space we recommend our newcompact angular ball bearing. With a cross section of 1x2inches it meets the dimensions of standard bearings andcombines high stiffness and precision with silent runningeven with high RPMs.

In all applications where two bearings are usually requiredto take the loads and moments our new compact bearingscan replace them both.

Bearing assemblies as low noise bearing

Two-sided elastomer bearingThis bearing was developed for particularly silent run andlow structure borne noise. This aim was reached by racerings of high-surface quality which are embedded intoelastomer. The rotational resistance is adjusted accordingto the application. This invention was patented.

The bearing proved to be successful in the range ofcomputer tomographs. It is suitable for speeds up to 6 m/s. Inner and outer ring are electrically insulated againsteach other.

One-sided elastomerbearing (hybrid bearing)This bearing was developed on the basis of the low-noisebearing but it differs from that by its additional stiffness.Regarding smooth and silent run both bearings arenearly equal.

The hybrid bearing is mainly used in cases where highloads and moments are to be sustained. The inner ring iselectrically insulated against the outer ring.

Angular ball bearingstandardThe double row angular ball bearing was developed forCTs with high RPMs. Here two rows of balls are runningin a defined way. The friction conditions are especiallyfavourable and the bearings are particularly stiff and freefrom clearance even in the tilted condition.

This bearing type meets very high demands for precisonand low running noise.

Angular ball bearing withelastomer inlayWe made good experience with the elastomer inlay fromwhich we want to benefit also for the angular ball bearing.The loudness level was even more reduced by theelastomer, the same is true for the structure-borne noise.

The elastomer is used in the stationary ring. The innerring is electrically isolated against the outer ring.

Franke bearings are proven in dailyoperation in numerous applications andmarkets.In all cases where the Franke bea-ring system is incorporated conse-quently into the design, cost effectivesolutions result.

The special advantages of thebearings are the space savingdesign together with high load capa-cities for loads from whatever direc-tion. The balls run on tough ringsfrom spring steel which are embed-ded in the mating structure. Loadcapacity and running behaviour aretherefore independent from thematerial of the mating structure,giving the designer a wide range ofmaterials from which to choose.

Numerous series provide a wideselection range from the LowCostversion to slim bearings and specialsolutions such as our angular ballbearings for CT-scanners.

The computer tomograph is equipped with alow-noise Franke bearing.This patentedbearing was developed particularly for thispurpose; its special merits are very smooth andsilent running, low current consumption,and high precision.

Technical Information

1. How to chose a bearing element or a bearing assembly

The selection respectively dimensioning of the bearing should be madebefore the beginning of the design work.

Parameters for the choice:- Permissible dimension and requirements to the material of the

bearing- Loading with collective loads and pertinent time shares in %- Number of revolutions respectively number of slewing motions and

slewing angle per time unit- Circumferential forces which are to be transferred by the gear- Any other operating conditions such as temperature, vacuum, clean-

room, humidity

(Please use the form on page 32.)

The catalogue serves to make an approximate selection of the bearing. Allthe necessary data are found on the corresponding page of the respectiveseries.

1.2 Static and dynamical load capacity, calculation

The indications concerning static and dynamical load capacity given in thecatalogue should be used for the pre-dimensioning. They are not sufficientfor the precise final dimensioning. The given load rating applies to radialloads. For optimal dimensioning you need the static, axial, radial, andmoment load rating, respectively the dynamical, axial, and radial loadrating.The axial values normally are higher by the factor 2. We recommend youto use the Franke calculation programme or to have the calculation madeby us.

2. Assembly and adjustment of bearing elements.

Bearing elements are composed of two inner and two outer race rings anda multipart segmented cage with balls. The race rings are open andtherefore their cross section can be elastically adapted when mounting.

The quality class of the balls is 3 (DIN5401). Only the balls which arecontained in the Franke consignment are allowed to be used. If balls getlost all the balls have to be replaced.The adjustment with preload is an important condition for longevity. Itguarantees that all races carry load and that the balls run optimally in theirdefined track.

2.1 Adjustment by means of washers

Adjustment by means of washers is the most flexible and economicallymost efficient way of adjustment because it allows the user to change therotational resistance subsequently. Washers can be ordered in differentthicknesses depending on the screw diameter (see accessories on page31).

Condition:

- Inner and outer structure have to be parted- The height “mH7” on the side of the parted mating structure must be

by 0.3 to 0.5mm smaller. The gap serves to take the washer.- The parted side of the mating structure should be fixed by a centring

collar to guarantee the parallelism of the races.

Mounting and adjustment

The race rings are inserted into the mating structure. The race ring bedscan be coated with grease in order to keep the rings in their position duringthe mounting process. The joints of the race rings which are on theopposite side of the same part are turned by 180°. Afterwards the partedside of the mating structure is put into its provided position*. Then the cagesegments with the balls are inserted and the bearing element is greased(see page 34: lubrication). Before the mating structure of the parted sideis closed the washers are put on the holes for the fixing screws. Theirthickness depends on the gap which is provided for them (see above).After tightening of the screws (see screws) the bearing assembly is turned2 to 3 times by 360° and the rotational resistance is checked. If themeasured value differs by more than 5-10% the thickness of the washershas to be changed and the procedure has to be repeated.

(* Applies to both adjustment methods 2.1 and 2.2)

2.2 Massive adjustment

With the massive adjustment the dimensional determination of theadjustment surface is obtained by grinding. With this method the highestprecision is reached because the separating surface of the parted side isform-fit and no tension bridges can be produced.

Condition:

- Inner and outer structure has to be parted.- An appropriate surface grinding machine has to be at disposal- The dimension “mH7” on the side of the parted mating structure must

be by 0,1 mm higher. This over measure is needed for adjustment.- The parted side of the mating structure should be fixed by a centring

collar which determines the parallelism of the raceways.

The re-lubrication quantity is calculated as follows:M = KKØ x h2/3 x X

h2 = height of bearing ring n mm (see page 20 resp. 24)KK¯ = Ball pitch diameter in mmm = Re-lubrication quantityX = Factor according to table 1 in mm -1

Re-lubrication periods:

The precise determination of the periods has to be based on the specificapplication and should therefore be defined by experiments. Approximatevalues are found in table 1. The factor X (table 2) is determined by the timevalue in relation to the operation time provided for your application.

Table 1:

Table 2:

Hint:

With standard bearings it is sufficient to attach one re-lubrication facilitybecause the lubricant is evenly applied by the bearing motion. Withslewing bearings you should provide at least 3 re-lubrication facilities(3X120¡). Generally it is possible to install a circular oil lubrication system.Please consult the lubricant supplier. For special applications (e.g. cleanroom or ultra high vacuum) we can manufacture lubricant-free bearings.

Calculation example:

Bearing assembly LDL, KKØ 500 mm, order no. 73105Y, circumferentialspeed 3m/s

Operation time approximately 16 hours per day

The re-lubrication period for 3m/s is 1000 hours (see table 1)= 1000 (h) /16 (h/day) = 63 days ~ three months with an operation time of16 hours per day.

Re-lubrication should be made every 3 months hence the factor X (table2) is rounded and amounts to 0.0003. The dimension h2 is 42 mm(according to page 25 in this catalogue).

m = 500mm x 42/3mm x 0.003g = 21 g

Hence the quantity for re-lubrication amounts to 21g ISOFLEX TOPASNCA52; it should be applied every 3 months. The durability of the lubricantis 3 years.

Vu Interval[m/s] [h]

0 bis < 3 50003 bis < 5 10005 bis < 8 6003 bis <10 200

Afterwards the cage segments with the balls are inserted and the bearingassembly is closed with the second parted side of the mating structure(adjustment ring). The clearance should be measured by means of a dialgauge after securing of the screws according to the instructions (seeunder “screws”) and after turning of the bearing assembly two to threetimes by a full rotation of 360°. Now the adjustment ring is again detachedand the measured value plus additional 0,02 to 0,03 mm is ground off bymeans of a flat grinding machine. (In order to guarantee the parallelismbetween this surface and the rest surface of the raceway the designershould provide a suitable rest surface beforehand!)After the grinding dust has carefully been cleaned off the ring is mountedagain as described, and the bearing is moved. Now the rotational resistanceis measured. If this value differs by more than 5-10% the procedure hasto be repeated. Finally the bearing assembly is greased via the providedlubrication holes (see “lubrication”).

Hint:

We recommend you to adjust a preload because tolerances which haveto be compensated are always to be encountered, even with optimummachining

3. Mounting and installation of bearing assemblies

Franke bearing assemblies are completed bearings and ready forinstallation, no matter whether it is a standard bearing from the catalogueor a custom-made specific version. The defined running accuracy, therotational resistance, the stiffness and the general features depend on themating structure and the correctness of the data indicated when ordering.So please pay attention to this aspect.

3.1 Lubrication and maintenance

The bearing should always be provided with sufficient lubricant in order tokeep the friction low and to avoid corrosion. All lubricants undergo anageing process which limits the durability. The best durability is reachedby fully synthetic lubricants. For the first lubrication of our bearings we useISOFLEX TOAS NCA 52 (Special grease of the firm Klüber, designationaccording to DIN 51502: KHC2N-50). The durability of this lubricant isabout 3 years. We recommend this grease also for our bearing elements.

As an alternative you can also use high-grade lithium soap greases on thebasis of poly-alpha-olefin or greases on the basis of mineral oil, accordingto DIN 51825-K2K-40. Any questions regarding specific features e.g.miscibility, aggressiveness, extreme temperatures, disposal, or applicationfields of a lubricant should be cleared up with the lubricant producer.

3.2 First lubrication

The quantity of lubricant needed by an antifriction bearing is relatively lowand adapts itself to the RPM. In cases where too much lubricant is usedthe flexing work increases the temperatures and consequently the lubricitycould be reduced or completely lost.This way the increased wear of the bearing reduces its longevity. Thequantity of lubricant is determined according to the free space inside thebearing assembly. 20 to 30% of the calculated volume has to be filled withlubricant. With slewing bearings we recommend 30-40%.

3.3 Re-lubrication and lubrication periods

The lubricity decreases as a consequence of wear and ageing. Thereforeit is necessary to complete lubricant or to exchange the total lubricantquantity (e.g. in case of heavy contamination). During the re-lubricationprocess the bearing has to be turned, the temperature should be thenormal operating temperature.

3.4 Lubrication and lubrication periods for the gear

We recommend an automatic lubrication device for the gear. With manuallubrication gear and pinion have to be sufficiently greased before being setto work. The lubrication period depends on the design and thecircumferential speed and therefore it has to be considered individually.

3.5 Screws

Principally the number and diameter of screws to be used for fixing thebearing to the mating structure has to be checked. The fastening screwsshould be tightened crosswise by means of a moment key. The momentdepends on the screw quality. (See table 3).

Table 3

To compensate settling effects the screws have to be re-tightened with theprescribed tightening moment. During the re-tightening process no otherforces should be exerted on the screws. The control has to be made after100 and after 600 operating hours. Where particular conditions occur (e.g.heavy vibrations) this period should be considerably reduced.

3.6 Rotational resistance

The preload of a bearing determines the rotational resistance. Thepreload depends on the respective series and on the ball pitch diameter(See respective diagrams). However these values are not irreversible butthey can be adjusted individually according the application.The stiffness of a bearing depends indirectly on the rotational resistance.The following thumb rule applies: the higher the rotational resistance thehigher the stiffness.

The increase of the rotational resistance caused by the seal S10 (seeaccessories) is approx. 1Nm/m circumference per seal. This value canvary due to dry run or and depends also on the surface quality.

3.7 Gear

Normally we supply the straight-tooth type (material 42CrMo4V)unhardened without offset profile. Material, type and quality can bechanged on request at any time.

The definition of the permissible circumferential forces in the catalogue isbased on the permissible bending stress at the tooth root. The maximumforces are related to extreme loads which are to be encountered e.g. withshort time shock loads which occur during starting and stopping. Theseare approximate values which can only be defined by a gear calculationon the basis of the data given for both components (bearing assembly andpinion).

3.8 Tolerances and precision

All tolerances and precision values are given on the respective cataloguepages. The highest possible precision is obtained, where the enclosingstructural parts are designed in such a manner that all diameters andsurfaces which correspond to each other can be machined in onechucking.

The running precision indicated in the catalogue refers to maximumvalues and can be improved by reducing of the tolerances.

The tolerance indication T=IT6 or T = IT7 is referred to the basic tolerancesdepending on the bearing diameter according to DIM ISO 286(see table 4).
