Sealing System Examples
Typical Hydraulic Equipment using Shamban Systems
In each individual case the type of system should be selectedbased on criteria such as friction, leakage, and cost. In thefollowing examples we have mentioned the main features foreach system as a guideline; however, the section describingthe individual product should always be consulted to ensurethat all operational requirements are fulfilled.
Utility Actuator Systems: Rod Applications
For general purpose hydraulic actuators, Shambanoffers a variety of simple and reliable sealing systems:
TurconR

Figure 1 Standard Rod Sealing System
The WedgpakR and ExcluderRDC standard sealingsystem (Fig. 1) is a simple and effective solution thatcombines long life with good leakage control. TheWedgpakR is an easy to install, foolproof design, offeringexcellent leakage control.
The ExcluderRDC is superior to the older garter springenergized scraper because it utilizes an uncut scraper ringand is sealed off by an O-Ring on the static side.

Figure 2 Alternative System I
TheGrooved Plus SealRII (Fig. 2) can be substituted for theWedgpakR in cases where an elastomeric contact seal isnot suitable due to high speeds or long rest periods for theactuator. This seal has nearly the same leakage control,but since it is a slipper seal, speeds of up to 15 m/s (49ft/s) are acceptable and adhesion is eliminated. Thegrooves on the dynamic seal surface provide pocketswhere the hydraulic fluid can accumulate and lubricatethe seal, therefore increasing seal life.

TurconR
VL SealR
Figure 3 Alternative System II
VL SealR (Fig. 3) is a good alternative for applicationswhere a dry rod is critical (and typical slipper seals allowtoo much leakage). VL SealR is designed to pump anyleakage back into the system. A double acting scraper suchas the ExcluderRDC is used in order to prevent leakage outof the system at the rod end. The VL SealR /ExcluderRDCsystem has the advantage of being extremely leaktight witha surface finish at max. Ra 0.2 µm.

The tandem VL SealR combines the low frictioncharacteristics of the slipper seal with a leaktightperformance. The dual edge ExcluderRDC closes theleakage by low pressure and static stand-by operations.
Although the HatsealRII and the WedgpakR have beenused for many years for high frequency systems, thetandemVL SealR system provides increased reliability andcan survive high frequency dither stroke applications withincreased service life.
Rod Applications with Pressure Relieving Seals
In some cases an interstage pressure build-up can beexperienced in a dual unvented sealing system. The followingfactors are contributing to this phenomenon:
- Stroke frequency- Stroke length- Pressure variation- Extrusion gap- Surface finish- Oil viscosity- TemperatureThe following systems are designed to allow the interstagepressure build-up to be relieved back into the system , whenthe system pressure drops or in the case of the StepsealRKduring the retract stroke of the rod.

Pressure relieving can also be achieved by using theVL SealR as a primary seal. The sealing lip will lift if theback pressure exceeds approximately 10 bars (145 psi).
VL SealR/WedgpakR configuration offers the optimumpressure relieving seal system, due to the VL SealR design.Pressure trapped in between the two seals is preventedfrom leaking through by the elastomer contact of theWedgpakR and the slight tilt of the VL SealR caused bybackpressure, allowing the oil back into the circuit.

For medium sized landing gear, it is an advantage to usea tandem sealing system with by-pass around the inboardseal. This means that initially the pressure drop is over theoutboard seal, and the inboard seal runs in a lubricatedenvironment. When a leakage is detected, the by-passcan be closed and operations continue on the inboardseal until the next scheduled overhaul.
On landing gears where severe shock strut deflection canbe expected, the use of SlydringR is recommended toavoid scoring caused by metal-to-metal contact of themoving parts.

Rotary Vane Sealing SystemA rotary vane sealing system consists of a rectangularcap seal with a centerplate, and an O-Ring to energizeand seal between the chambers. The corner seal can bedesigned in various shapes to control the leakpathbetween chambers and rod. The TurconR WedgpakR
is positioned as rotary seal with a small elastomercontact to prevent leakage even at low pressure. Finally
the ExcluderRDC prevents contamination from enteringthe system. If space is available, a SlydringR isrecommended between the rod seal and theExcluderRDC.

BrakesBrake pistons equipped with a spring energized TurconR
VarisealRH to take pressure and temperature variation,combined with the tight and efficientTurconRExcluderRDC, Series E, have proven to be veryreliable. The advantage of using VarisealR (springenergized TurconR jackets) instead of elastomer contactor energized seals is that brake systems often exceed the
temperature capability of the elastomer. Springenergized seals can go from -100_C/-148_F to+260_C/500_F, and metallic springs address most fluidcompatility problems.
The Spring Liner protects the brake housing from wearand abrasion from the spring.

TurconR Seal Materials
TurconR materials are carefully formulated proprietaryblends and are based on premium-grade PTFEfluoropolymer resins. Fillers are added that improve sealmaterial properties. Fillers improve wear extrusion,resistance and high-temperature properties of TurconR.The key features of TurconR seal materials are as follows:
Low Friction
TurconRmaterials exhibit the lowest coefficient of frictionof any known solid, as low as 0.04 unlubricated onpolished steel. The friction values obtained underlubricated conditions will be smaller. A unique propertyis the very low static coefficient of friction of TurconR
which results in extremely low breakout friction. TurconR
materials do not adhere to their mating surfaces,therefore eliminating any worries about stick-slip indynamic applications.
Chemical Compatibility
TurconR materials are chemically inert in essentially allindustrial chemicals and solvents, even at elevatedtemperatures and pressures. A single TurconR materialcan handle an extremely wide range of solvents, acids, orother corrosive media.
Temperature Range
TurconR materials can operate at service temperaturesfrom -196_C /320_F up to 260_C /500_F, (even furtherunder special conditions) but it is necessary to limit otherworking conditions, such as speed and pressure, whenthe temperature reaches the limit.
Temperature Cycling
In elastomeric seals, temperature cycling causesmaterial degradation leading to compression-set of theelastomer. TurconRmaterial properties, however, are notaltered by cycling temperatures. TurconR also does notcontain plasticizers or any other ingredients which coulddegrade at temperatures below 300_C (572_F).
High Surface Speed
TurconR materials generate far less heat than othermaterials, such as elastomer, polyurethane, etc. Ingeneral, surface speed can go up to 15 m/s, dependingupon seal design and working conditions. Speedexceeding 20 m/s has been achieved under specialconditions.
Aging
TurconR properties do not significantly change overtime. TurconR does not age and will not embrittle ordegrade when exposed to severe-weatheringconditions of heat, light, water, salt spray, etc. This isuseful when seals might sit idle for years and still berequired to perform with complete reliability.
Resilience
TurconRmaterials may experience ”cold flow” or creepunder continued thermal or mechanical stress becausethey do not have the resilience of elastomers.Consequently, TurconR materials require anexternal-loading device such as a metal spring or anelastomer. This is required to provide the radial forcewhich compensates for seal wear, cold flow, and thenormal variations in gland dimensions due totolerances or eccentricity.
Wear Resistance
TurconR materials are formulated to enhance wear lifeat high speeds, pressures, and temperatures throughthe addition of fillers such as carbon fiber, glass fiber,molybdenum disulphide and others. TurconRmaterialsachieve wear values that exceed the demands of manydifficult sealing environments.
Radiation
TurconR is not recommended for an accumulatedradiation dose above 7 x 102 Gy (7 x 104 rad). The largeflourine molecules in the PTFE chain make good targetsfor radioactive particles. The molecular-chain structure isdamaged by scissure when exposed to radiation, resultingin lowered tensile strength and eventual disintegration. Inhigh-radiation service, other fluoropolymers such as EFTEand PCTFE or ZurconR materials are recommended.
Polytetrafluoroethylene (PTFE) Properties
Since TurconRmaterials are based on premium-grade PTFEresins, the general properties of PTFE may be of furtherinterest. PTFE has excellent electric properties such as a lowdielectric constant and a very high dieletric strength, even atelevated temperatures. PTFE will not sustain fire in pureoxygen. Virgin PTFE is physiologically inert.
The water absorption of PTFE is 0.01%. PTFE does notabsorb fluid to a level worth mentioning other thanfluorinated-cooling media (e.g. Freon). Fluorinated fluidscan cause a reversible weight increase of approximately5% accompanied by dimensional increases ofapproximately 1%.

TurelR Elastomer Materials
Many of the Shamban seal designs are composite sealswith an elastomer element as an integral part of the seal.For this reason it is very important that we are in controlof such important seal design parameters as elastomerswell, shrinkage during molding, compression set,compatibility and tolerances.
Through extensive testing in our own test laboratory wemake sure that our materials are manufactured to ourspecifications. A number of the materials have also beenapproved for a QPL as part of a US Government supportprogram.
Selection of elastomer material for a hydraulic fluid is acritical issue since the elastomer materials are moresensitive to fluids than other materials. Chemicalreactions and physical behavior can be very damaging ifthe wrong material is selected.
Even though the specifications ensure compatability,different behaviors can result due to the number and typesof additives used in the oil. It may be necessary to conducta soak test at elevated temperature in order to verify theperformance for critical applications. Contact yourShamban sales engineer for assistance.
Following points are important when designing the sealsystem:
Chemical Compatibility
Compability with the most common oil types can be foundin Table IV, page 16. For other medias please contact yourShamban sales engineer. See also note in section below.
Nitrile MIL-P-83461 versus MIL-P-25732C
Due to the chemical composition of the nitriles, it is veryimportant to separate and use them where the functionalbehaviors are optimized.
Compression Set(Static)
Wearlife(Dynamic)
MIL-P-83461(peroxide cured) + -
MIL-P-25732C(sulphur cured) - +
This indicates that dynamic elastomer contact seal shouldbe MIL-P-25732C in order to optimize seal liferequirement.
Temperature Range
Most TurelR materials can be used in MIL-G-5514F typeII systems (-54_C to +135_C / -65_F to -275_F). The lowtemperature dynamic cycling limits vary according toelastomer type.
Shamban offers other TurelR elastomer compounds whichexpand this temperature range. Please refer to Table III onpage 15. The use of spring energized VarisealR canexpand the temperature range even further.
Temperature Cycling
The effect of temperature cycling on elastomeric sealsresults in compression set which means that the elastomermaterial loses its elasticity over time. For TurelRmaterials,this effect is kept to an acceptable minimum if they arewithin the indicated temperatures.
Cold Temperatures
Elastomer materials contract approximately 10 timesmore than steel in cold environments. The materialbecomes stiffer, loses its flexibility and when passing thelower limit it reaches the glass transition stage whereby itbecomes extremely brittle. Physical properties will recoverwhen temperatures go up again. (Increased squeeze canimprove the performance.)
Hot Temperatures
Elastomer materials soften and loose its physicalproperties when passing the upper temperature limit.Physical properties will not recover and it will take apermanent compression set. (Compression set varies withelastomer type).
Surface Speed
The speed of the dynamic surface in contact with anelastomer contact seal should be kept below 3 m/s (9.8 ft/s)to avoid damage to the elastomer.
Aging
The maximum recommended storage time is shown inTable III. This is only valid if the elastomer is stored undercontrolled conditions in light and airtight packaging.

Surface Finish (Recommendations)
Surface Finish Recommendations
Current industry standards for surface finish range from0.2-0.4 μm Ra (8-16 μin) per Mil-G-5514 to 0.25-0.50μm Ra (10-20 μin) for general applications. Past industryexperience suggested that surfaces smoother than 0.2 μmRa (8 μin) did not allow for ample lubrication of seals,while surfaces rougher than 0.4-0.5 μm Ra (16-20 μin)prematurely wore seals, resulting in short life. With thesurface measuring and finishing equipment availabletoday, surface finishes smoother than the currentstandards have shown to be suitable and can actuallyimprove overall seal performance.
Investigations into surface finish measurement equipmentand capabilities, along with finishing methods, haveresulted in functional seal testing being performed todetermine and verify surface finish recommendations forimproved seal performance. The followingrecommendations are a guide to defining the propersurface finish for dynamic sealing applications:
Ra = 0.1 - 0.2 μm (4 - 8 μin)
Rz = 1.0 μm maximum (40 μin)
Rp = 0.6 μm maximum (24 μin)
tp (Mr) = 50-70% @ depth p = .25Rzrelative to a ref. line c = 5% tp
These general recommendations apply to all types ofsealing surface finishes including plated or coatedsurfaces and bare, hardened metal surfaces.
Additionally, the surface profile should have a”plateaued”appearance as the illustration of Figure 29 shows. Asurface with a high concentration andmagnitude of peakshas been shown to cause excessive seal wear. A surfacerelatively void of peaks but including valleys forlubrication retention is more suitable for sealingapplications.
Direction or ”Lay” of Finish
Each of the many different methods used to obtain aspecific surface finish - turning, grinding honing,ballizing, polishing, etc. - produces a characteristicdirection or ”lay” to the surface. This factor alone can havean effect on sealing performance and wear patterns incertain applications. To obtain the best seal performance,avoid finishing methods which promote the formation ofleak-paths in your application. For example, avoid astrongly axial lay in a reciprocating rod-seal application,or a definite spiral pattern on the shaft in a rotaryapplication. Consult your Shamban sales engineer forfurther information.
Mating Surface Hardness
The hardness of a mating surface affects sealperformance in several ways. A harder material improveswear life by resisting the tendency of seals to damage themating-surface finish. If thematingmaterial is too soft, theseal will burnish or damage the surface. Harder matingsurfaces also allow the user to specify certain tougher,longer-lasting TurconR seal materials (such as Carbonfiber filled T29) which would not be recommended onsofter hardware surfaces. Harder mating surfaces have atendency to lower the running friction of a seal.
A seal will polish its mating surface, especially if it is asofter metal. For example, a reciprocating rod made ofstainless steel with a hardness of 28 to 30 Rockwell C anda finish of Ra 0.6 µmwill generally be polished by the sealto a finish of Ra 0.3 µm or better over a short time. Sealfriction andwear will then decrease accordingly. Materialsthat are harder than 44 Rockwell C do not polish as easily.The abrasive nature of a rough finish can cause excessiveseal wear during the early burn-in period. Therefore, theharder the mating surface, the more important it is to startwith a smooth finish.
Substrates
In most applications an unplated, uncoated shaft is morethan adequate. Typical mating-surface materials arelisted in the Table IX, page 26 and Table X, page 27. Thesematerials (and others not listed) can also act as substratesfor platings or coatings to achieve higher hardness values.An important property to consider in such cases is theability of the substrate to support the plating. For example,when a high-pressure load is exerted on a seal runningagainst a hard-chrome plating supported by a softsubstrate (such as 300 series stainless steel) the platingmay peel or crack and then abrade the seal. A bettersubstrate would be stainless steel Type 440C (hardened to44 Rockwell C) or an alloy steel such as 4340 in thefully-hardened condition.
Platings and Coatings
Seal designs run well against unplated surfaces atmoderate speeds and pressures. In high-speed rotary orhigh-pressure reciprocating service, harder surfaces arepreferred. Several examples of platings and coatings (nota complete list) are given on page 27.
For further advice on platings and coatings, please consultyour Shamban sales engineer.

Busak+ Shamban Edition April 2004
Seal Material
Seal material selection affects mating-surface hardnessrequirements. When an application requires the longestpossible wear life under moderate to severe conditions,the seal material should be one of the harder, highly-filledTurconR blends. For example, TurconR T29 is verywear-resistant but contains carbon fibers that can abradesoft mating surfaces. These materials should only be runagainst materials with hardness values of 45 to 70+Rockwell C.
Supporting Test Data
Functional dynamic seal testing was conducted underdifferent evaluation programs that were designed to studysurface finish effects on seal performance. Various typesof surfaces (coatings) were evaluated throughout thesetests. Not all of the tests were performed utilizing the sameconditions or test seals. Some of the test results andobserved trends relative to surface finish effects on sealperformance are reported here as supporting data.
Functional seal testing utilizing commercially availableinduction-hardened, chrome-plated (IHCP) piston rodmaterial meeting the 0.2-0.4 μm Ra finish requirementhas typically shown much variation in seal performanceresults. Analyzing test results, the test parameters,equipment and methods concluded that the variationswere most likely due to differences in the surface texturesof the test rods.
Further testing using IHCP rods finished to the extremes ofthe 0.2-0.4 Ra requirement confirmed this suspicion. Atest matrix was conducted whereby four combinations offinishes were evaluated: (Ra in μm)
- 0.2 Ra ground
- 0.2 Ra ground, polished
- 0.4 Ra ground
- 0.4 Ra ground, polished
The results of this study were somewhat surprising anduncovered some effects that surface finish can have onseal performance. In general, the polished surfacesperformed better with respect to seal leakage and wear,which was expected. But the polished 0.4 Ra surfacesallowed better seal performance than the 0.2 Ra ground;this result revealed the need for more in-depth studies ofthe effects of surface texture and type. Not only was the0.2-0.4 μm roughness average finish callout inadequate,but the type of finish (ground only vs. ground andpolished) was also significant to seal performance.
A test program was conducted to evaluate proposedimprovements to a standard industrial sealing system fora reciprocating application. A comparison of different
surface finishes was part of this study. The test rods werenot plated; an alloy steel hardened to Rc 36-40 was thetest rodmaterial. For one of the tests, amaximum Rp value(peak height) was set for the test rod in addition to the Racallout. The wear of the primary seal element wasmeasured after 1 million cycles. The seal that ran on themore tightly-controlled surface finish showed a significantadvantage with respect to wear as Figure 22 illustrates.Leakage performance was identical between the two tests.

In comparison to the TurconR-contact seal performancedata, the elastomer-contact seal performance gains arenot as significant. This is mostIy attributed to basic sealconfiguration and functional differences between the twotypes of seals.
Aluminum is occasionally used for cylinder barrels whereweight is a major concern or the application is relativelylight duty, as in pneumatics. For increased corrosionprotection and wear resistance, aluminum alloys areusually hard-anodized. An evaluation was performedwhere hard-anodized aluminum was compared totungsten carbide coated aluminum. Both TurconR-contactand elastomer contact seals were tested to the followingparameters:
Pressure : 3000 psi constant
Stroke : 3 inches
Stroke Rate : 1 Hz

Again, significant improvements in seal performancewere observed between the different surfaces.
Throughout these supporting data, seal performancegains were demonstrated through the use of surface finishtechnology and advanced coatings. The exactcontributions from either the coatings or actual surfacefinish improvements to the enhanced seal performanceswere not quantified. Regardless, significant performancegains, especially in the case of the TurconR-contact seals,were shown as a result of improved surface quality.
Conclusion
Surface finish quality is directly related to dynamic sealperformance. Properly defining, measuring andcontrolling surface finish quality is critical to the functionalreliability and service life of a seal. Ra alone is not anadequate description of a sealing surface, however, caremust be taken to prevent over-specifying surface finishrequirements.
Many different types of surfaces are suitable for sealingapplications as well as methods and equipment used toobtain satisfactory surface finishes. Advanced coatingsand finishes, typically investigated as replacements tochrome plating, have demonstrated good performancegains with respect to dynamic sealing in hydraulicapplications.

Surface Finish (Measurement Methods)
Ra - Arithmetic Average Roughness
Roughness averages are the most commonly usedparameters because they provide a simple value foraccept/reject decisions. Arithmetic average roughness, or Ra,is the arithmetic average height of roughness-componentirregularities (peak heights and valleys) from the mean line,measured within the sampling length, L. See figure 29.
The measurements are taken as the fine point of the styluson a profilometer which traverses the sampling length onthe surface being measured.

Figure 29 Surface Finish - Ra Versus Rq
Rq - Geometric Average Roughness
Rq is the current term for what was formerly calledroot-mean-square or RMS. Rq is more sensitive tooccasional highs and lows, making it a valuablecomplement to Ra. Rq is the geometric average height ofroughness-component irregularities from the mean linemeasured within the sampling length, L. Compare to Ra inTable V.
The main difference in the two scales is that Rq amplifiesoccasional high or low readings, while Ra simply averagesthem. For a given surface, therefore, the Rq value will behigher than the Ra value (by approximately 11%). That is,a surface finish that measures Rq 0.5 µm is equivalent toapproximately Ra 0.45 µm.

Improved Measurement Methods
The Ra measurement does not give a true picture of thereal surface profile. The finish process plays a veryimportant role in the outcome. In particular, the openprofile ”Peak Structure” can seriously affect sealperformance, as its jagged structure can cut and nick theseal surface. On the other hand the closed profile form”valley structure”, gives improved seal performance,because the valleys retain fluid and lubricate the runningseal surface. Please see Table VI.

The optimum view of the surface structure is a3-dimensional computerized picture showing not onlypeak, core and valley, but also direction of ridges andchannels in the surface structure. Such pictures can be veryvaluable in evaluating seal performance. This method ofmeasurement will expose widely varying surface profilesdependent upon basematerials, platings or coatings, andthe process used to produce the surface.

Relationship between hardness and tensilestrength
The approximate relationship between the hardness of ametal and its tensile strength is shown by the followingformula in which B = Brinell hardness number.
Tensile strength = B x 515 (for Brinell numbers up to 175)Tensile strength = B x 490 (for Brinell numbers over 175)
These formulas give the tensile strength in pounds persquare inch and apply only to steels. This relationshipbetween hardness and tensile strength does not apply tononferrous metals with the possible exception of certainaluminum alloys.
Dynamic Alignment
Proper alignment of dynamic mating surfaces is animportant factor in improving seal performance. A wellaligned shaft and housing assembly will last longer, leakless, and operate more reliably at higher speeds andpressures. There are three types of misalignment whichshould be avoided during the hardware-design phase.
Angular Displacement
When the axis of a rod or piston moves at an angle awayfrom the true centerline, a condition called ”angulardisplacement” exists. It affects sealing integrity by loadingthe seal unevenly and puts undue stress on theelastomer/spring. The seal wears more rapidly and mayfail before its maximum wear life. Although this conditionis often detected in the static condition, it is essential tomeasure it dynamically as well and correct anymisalignment that is found.

Busak+ ShambanEdition April 2004
Eccentricity
In rotary service, when the shaft rotates about its own axisbut is offset from the centerline of the housing, a conditionof eccentric misalignment exists. In reciprocating service,the condition occurs when a rod or piston moves parallelto its own centerline but is offset from the true centerlineof the housing or bore. In this situation the seal is stressedmore heavily on one side, resulting in excess wear, andinsufficiently loaded on the opposite side causingleakage. When examining the used seal, it may showdamage on one side only. There may also be a visibledifference in wear rates on opposite sides of the seal.
Bore centerShaft center
Shaft to housingmisalignment
Figure 34 Eccentricity
Shaft Runout
Shaft runout occurs when a shaft is rotating about its owncenterline which is offset from the true centerline of thehousing. The shaft centerline is not stable in one place asin eccentric misalignment, but is itself moving around thetrue centerline of the housing, resulting in a ”wobbling”effect. This condition stresses the seal around all points onits diameter. Shaft runout is measured with a dial indicatorand is expressed in ”thousandths of an inch” TIR (Total
Indicator Reading). Runout causes a seal to wearprematurely but with more of an even wear pattern thanthat of ”eccentric misalignment”. It is often a contributorto early leakage since a potential leak-path iscontinuously formed as the ”high point” of the shaftpasses each point on the sealing contact surface.
True center of rotationShaft center
Shaft to housingmisalignment
Figure 35 Shaft Runout
Excessive Runout
The amount of shaft runout in a hardware design canrange from ”minimal” (has no significant effect on sealperformance) to ”moderate” (less-than-optimum wearlife) to ”excessive” (causing an unacceptable early failure).The amount that is considered ”excessive” can vary fromone application to another depending on shaft speed,fluid media, and the limits specified by the designengineer concerning leakage rates and wear life. It alsodepends on howmuch runout a particular seal design canhandle. Some seal designs can handle more runout thanothers.

Finite Element Analysis (FEA)
FEA is a technique by which a complex geometry, such asa sealing element, is divided into small, simply shapedentities. Using results from simple test methods designedto provide a reasonable measure of the properties of theseal in the end application, you can construct elementaryequations relating the material properties and thecomplex loads of the behavior of the entire complexgeometry. These results can then be verified using eithertraditional test methods or simple test methods designedto isolate the behavior of one feature of the seal assembly.
With FEA, the seal designer can screen newmaterials anddesigns of the computer rapidly, and limit the number ofdesigns nessesary to be fully tested. This screening speedsthe development cycle. Some additional benefits includequickly predicting the performance of a design in a varietyof application conditions, providing input between theseal and the hardware conditions, and uncoveringportions of the seal material/seal design interaction.

Seal Quick Reference Guide
Sealing elements have a decisive influence on the design,function, and service life of hydraulic and pneumaticcylinders and systems.
Leakage control, friction control, resistance to wear andextrusion, chemical resistance, resistance to high and lowtemperature extremes, compact form, and ease ofinstallation are demanded in order to meet the industryrequirements for a functional sealing solution.
The significance of the performance parameters and theirlimits determines the requirements of the sealingapplication. Shamban has developed a unique andcomplete range of seals to meet the challenging demandsof aerospace applications. Using optimized geometries,proven designs, and innovative materials, Shambanoffers aerospace customers a wide range of sealingsystems.
To select the most appropriate seal type and material, itis necessary to first define all the desired functionalparameters. Table XI on pages 30 - 35 can be used tomake an initial selection of seals and materials accordingto the specific requirements of each application.
The second column of Table XI contains the number of thepage on which further general information can be found,including specific design and installation instructions onthe particular seal type and materials (or materialcombinations with multi-element seals, e.g. Plus SealRII).
The quality of the mating surface is explained in thesection ”Surface Finish”, pages 17 - 23. Because surfacetexture has such a decisive influence on the functionality,reliability and service life of the seal system, it is importantthat these values are understood and applied.
Please do not hesitate to contact our ApplicationEngineering Department to request further informationand assistance on specific applications and to answertechnical questions.
Note on Ordering
The multi-element seal assemblies presented in thiscatalog are supplied as complete sets. The assemblyincludes the seal and proprietary elastomer energizingelement, such as the Plus SealRII which contains a TurelR
elastomer and TurconR cap seal.
Older seal designs not represented in this catalognaturally continue to be available. For all newapplications, we recommend you use the seal types andpreferred sizes listed here.

TurconR VL SealR*
Description
The TurconR VL SealR incorporates theoretical andempirical experience, in a new generation seal for the 21st
century.
The VL SealR has been developed over the past few yearsas a new generation unidirectional Rod seal. The designhas taken the latest empirical and theoretical experienceinto account in order to optimise performance, friction,leakage and service life. This has been achieved throughin-house testing and qualified in customer applications.See test section.
The back-pumping effect allows the seal to relievepressure trapped between tandem seals or between sealsand double-acting scrapers.

Figure 40 TurconR VL SealR
Method of Operation
The sealingmechanism of the TurconR VL SealR (Figure40) is based on the hydrodynamic properties of the seal.The specially formed seal edge has a steep contactpressure gradient on the high pressure side and a shallowcontact pressure gradient on the low pressure side. Thisensures that the fluid film adhering to the piston rod isreturned to the high pressure chamber on the return strokeof the rod. This prevents the micro-fluid layer, that iscarried out of the high pressure chamber when the pistonrod is extended, from causing leaks.
This return delivery property prevents the build-up ofinterstage pressure normally associated with tandem sealconfigurations (Figure 41). Interstage pressure dependson the system pressure speed, the stroke length and thegroove design.

Advantages
Compared with current rod seals, the followingparameters have been improved:
- Seal gland: in accordance with MIL-G-5514 / AS4716.0 b/u width (not available in 000 series).
- Tighter leakage control.
- Lower friction: (reduced contact area between seal andmating surface).
- Simplicity of design, using standard size O-Ring.
- Featuring the TurconR StepsealR back pumping effect.
- The seal geometry prevents seal roll at low or shufflingpressure.
- Recommended surface finish max. Ra 0.2 µm / 8 µinch.

TurconR Plus SealRII
Description
The TurconR Plus SealRII, with a long, successful history, isan evolutionary improvement of the Double DeltaR. It is fullyinterchangeable with the Double DeltaRII in mostapplications.
Plus SealRII Cap
Elastomer
p
Figure 46 TurconR Plus SealRII
Method of Operation
The sealing effect of the Plus SealRII comes from the slightinterference of the seal cap with the rod or bore combinedwith the preload from the compressed elastomer. As thepressure increases, the system pressure joins forces with theelastomer and increases the loading of the seal capsignificantly.
The substitution of the proprietary lemon shapedelastomer under the Plus SealRII cap instead of atraditional O-Ring allows the cap to be thicker forincreased wear life. The new elastomer element alsoactivates the seal cap over awider area providing a lowerunit loading.
p p
Double DeltaRII Plus SealRII
Figure 47 Pressure Distribution
The Plus SealRII elastomer is carefully profiled to fit insidethe cap and supports the corners to prevent them fromsinking away from the sealing surface. This reduces the oilfilm under the seal to an absolute minimum.
Free cross-section Installed cross-section
Figure 48 TurconR Plus SealRII Cross-Section
By choosing the grooved version, a further decrease in thefilm thickness can be achieved. The grooves increase thenumber of pressure peaks that the oil filmmust pass under.Another advantage of the grooved seal is that the groovesserve as an oil reservoir when the seal is static. When theseal starts to move, the oil film is quickly re-establishedunder the sliding surface to lubricate the seal. This isespecially important in applications where the stroke isshorter than the seal width and it provides a generalimprovement in wear life. Ask for Shamban test reportR1069.

The zero back-up width of the seal is generally preferredeven if a wider groove is available in smaller diameters.The extra space in a wider groove is used more efficientlywhen filled with back-up rings. This increases the seal lifewithout notably changing the friction.

Where the Plus SealRII is subjected to pressure from bothsides alternately, it should always be equipped withsidewall notches, which allow the pressure to properlyactivate the elastomer (Fig. 51). The Plus SealRII for pistonuse is equipped with notches as standard whereas the rodversion must be specified with notches if they are deemednecessary.
A seal without notches can allow ”blow-by”
A seal with notches prevents ”blow-by”

Using a seal without notches may allow ”blow-by”, whichis a situation where the pressure shoots over the top of thePlus SealRII cap and forces the seal down into the groove.See also SAE document AIR 1243.

TurconR Double DeltaRII

Busak+ Shamban Edition April 2004
TurconR Double DeltaRII
Description
The TurconR Double DeltaRII is the original seal designthat was developed to improve the performance of theO-Ring and Back-up Rings that were used in theMIL-G-5514F/AS4716 and older versions of that standard.
The TurconR Double DeltaRII represents a balancebetween the cap thickness and the squeeze of the O-Ringwithin the MIL-standard groove.
Double DeltaR
Capp
Figure 55 TurconR Double DeltaRII
Method of Operation
The O-Ring preloads the seal cap in the thin, flexiblemiddle section and provides good leakage control evenat low pressures.
In addition to the O-Ring preload, when the systempressure is added the oil film under the seal is furtherreduced. Double DeltaRII will always allow an oil film tobe dragged across the sealing surface. This oil film isnecessary to ensure a long service life for the DoubleDeltaR.
For use of notches and grooves, please see the sectionPlus SealRII, pages 50 - 53.

Figure 58 TurconR WedgpakR
Method of OperationThe small elastomer contact area of the WedgpakR
design results in a slipper seal-like performance with lowstatic and dynamic friction. At the same time, theelastomer wipes the surface efficiently providing excellentleakage control. The WedgpakR Back-up Rings providesupport and extrusion protection for the elastomer.
Originally designed as a static seal, theWedgpakRhasnow proved to be an excellent seal for dynamicapplications typically demanded in flight controlactuators. The WedgpakR is also used in gas/oilseparators both at high and low pressures.

TurconR HatsealRII
Description
The TurconR HatsealRII is one of the original highperformance seals Shamban developed for the aircraftindustry. It combines the advantages of the elastomercontact seal with those of the slipper seal.
The HatsealRII was designed for demanding aerospaceapplications and is operating successfully in both militaryand commercial hydraulic components. The HatsealRIIcombines the low leakage advantages of an elastomercontact seal and the long life characteristics of TurconR
contact seals.

Figure 61 TurconR HatsealRII
Method of Operation
The HatsealRII can be divided into 3 zones each with aspecific function, (Figure 62).
Zone 3Zone 2Zone 1
p
Figure 62 HatsealRII, 3 Zone Specific Function
Zone 1 Elastomer contact area
The elastomer has a small but well-defined contact areawhere the oil film on the rod is reduced almost to zero.Dueto the minimal elastomer contact, the friction of the sealis low. This ensures long life performance of the seal.
Zone 2 Slipper Seal area
In this area the TurconR platform is energized by themainbody of the elastomer to work like a slipper seal. Thissection will often run dry but since the TurconR materialshave very low coefficients of friction, this will not damagethe seal. In the unlikely event of a damaged elastomer lipin Zone 1, the slipper seal part will continue to work andgive a leakage performance like a slipper seal.
Zone 3 Back-up Ring area
The built-in Back-up Ring protects the seal from extrusioneven at high operating pressures or speeds. For increasedextrusion gaps and higher temperatures, a number ofspecial versions have been developed (see Figure 67).
Advantages
- Built-in redundancy- Zero leakage- Stick-slip free operation- High frequency applications
Technical Data
Operating pressure: 35 MPa (5000 psi)
Speed: 3.0 m/s (9.8 ft/s)
Temperature range:-54°C to +200°C(-65°F to +390°F)(depending on elastomer material)
Clearance: As per MIL-G-5514F/AS4716,higher with corner reinforcement.

TurconR AQ-SealR5* (For use in MIL-Standard Grooves)
Description
The TurconR AQ-SealR5 is a patented development of theproven standard AQ-SealR.
The AQ-SealR5 is a double-acting piston seal designedfor reciprocating or helical movements.
The AQ-SealR5 is comprised of a dynamic sealingelement in TurconR with a limited footprint elastomericQUAD-RINGR1) Seal inset centrally into its sealing face. Theseal ring is energized by two elastomeric O-Rings.
p QUAD-RINGR Seal
TurconR Seal ring
Figure 71 TurconR AQ-SealR5
Method of Operation
The AQ-SealR5 combines the benefits of a low-frictionTurconR slipper seal with the high sealing characteristicsof an elastomeric seal by incorporating a limited foot printQUAD-RINGR Seal in the dynamic sealing face. Thisoptimizes leakage control while minimizing friction.
The unique characteristics of the AQ-SealR5 are thespecial seal profile with a defined seal edge and the useof two O-Rings as energizing elements to optimize thepressure profile.
Diametral Clearance
The AQ-SealR5 can be installed in MIL-G-5514 F/AS4716(-300 and -400 sizes only) glands using the standarddiametral clearance. If a larger clearance is needed or if thehardware deflects excessively during operation, the diametralclearance will increase. In this case we recommend the useof SlydringR bearing rings with the AQ-SealR5. Please seesection ”TurciteR SlydringR/LuytexR SlydringR”, page 114.

TurconR VarisealR

Busak+ Shamban Edition April 2004
TurconR VarisealR
Design Concept
VarisealR is a spring-energized seal. The VarisealR
performs reliably in a wide range of applications whereconventional elastomeric seals fail due to chemical attack,extreme heat or cold, extrusion, friction or compressionset. The basic VarisealR design has two elements:
1. A pressure-actuated, ”U-shaped” jacket.
2. A metal spring.
The U-shaped jacket allows the system pressure toenergize the sealing lips, forcing them against the matinghardware with higher load as the system pressure rises.
The VarisealR is machined to very close tolerances,using only premium-grade materials. Each design isavailable in imperial and metric dimensions. Thestandard size range includes diameters from 3 mm(0.12 in) to 2500*) mm (8 ft).
System pressure
Figure 76 TurconR VarisealR Energized bythe System Pressure
Spring Load
The VarisealR is energized by a spring made fromstainless steel, HastelloyR, or ElgiloyR. The springprovides the load required for sealing when the systempressure is too low to fully actuate the lips. The springalso compensates for variations in gland tolerancesandnormal wear of the seal. As a seal loading device, ametal spring is more accurate for the control of frictionthan other devices, such as O-Rings.
See Spring Types, Table XXIV, page 70 for spring selection.
*) with extended size capability available.
Spring force
Figure 77 Spring Force
Jacket Material
VarisealR jackets are made from a variety ofhigh-performance polymers. There are two categories ofmaterial available:
1. TurconR Engineered-polymer compounds,based on low-friction TurconR resins, are foundin the majority of VarisealR applications.
2. ZurconR Compounds have outstandingabrasion-resistance.
See TurconR and ZurconR Seal Materials, pages 12 and13 for material selection.

Spring Types
A metal spring is incorporated in the design to provideelasticity to the seal. The spring makes the sealpermanently elastic despite changes in operatingtemperature, pressure or chemicals. Each of the springtypes found in the VarisealR has unique properties thataffect seal performance. The two most importantproperties of the spring - besides the corrosion resistanceof the metal - are its load value and deflection range. Thespring load has influence on the sealing ability, friction,and wear rate of the seal. The deflection rangedetermines the ability of the VarisealR to take up wearand compensate for variations in gland dimensions dueto hardware tolerances or eccentricity.
V-Spring (Cantilever)
This spring, used in the VarisealRM types and the RotoVarisealR, operates as a set of ”cantilever beams”extending from an arc at the bottom of the spring. Theshape of the spring causes the load to be focused on thefront edge of the sealing lip, contributing to the positive
wiping action of the seal. A Cantilever-beam spring has amoderate load and deflection range.
Helical Spring
Helical spring, used in the VarisealRH types, has a muchhigher unit load and a shorter deflection range than theother spring types. It is therefore excellent for staticapplications or very slow speeds where friction andwear arenot the primary concerns. The high spring load makes theVarisealRH suitable for applications with low temperatures.Under these conditions the 200 Series or larger is prefered.
SlantcoilR Spring
The patented SlantcoilR Spring, used in the VarisealRW,types consists of round wire formed into slanted coils. Thecoils load the seal radially.The SlantcoilR Spring provides a unique spring-loadingcharacteristic. The spring gives a relatively constant loadover a wide deflection range. This allows more accuratecontrol of friction during the working life of the seal.

Special TurconR VarisealRHi-Clean
All VarisealR with V-shaped springs are available with thespring groove filled with silicone.The silicone prevents entrapment of biological contaminantsin the seal, making the seal easier to clean.
The VarisealRHi-Clean is also used in applicationsworking in dirty environment such as mud, slurry or sandwhere the silicone maintains the flexibility of the springand seal lips by keeping media out of the spring groove.
VarisealRHi-Clean is ordered by adding a (D) after thematerial code.

Busak+ Shamban Edition April 2004
TurconR Dual Piston Ring
Description
The Dual Piston Ring Set consists of two TurconR ringseach with a step-cut. These rings are activated by a waveshaped stainless steel expander. On the inside of theTurconR rings there is a small notch into which a tab onthe spring fits. This prevents the rings from rotating relativeto each other. When installed correctly the step-cuts of thetwo rings will be separated by 180_.
TurconR
Piston Ring
Spring
Figure 94 TurconR Dual Piston Ring Set
Method of Operation
With zero or low system pressure, the two piston rings arekept in contact with the bore by the spring force. As thepressure increases it will act on the side and innerdiameter of the rings forcing them up against the bore.
The tolerances on the groove width and the width of therings are very tight which means that the Dual Piston Ringcan be made to fit the groove closely. This results in a sealthat reacts to pressure changes very quickly, a feature thatis used to the full extent in modern fly-by-wire flightcontrols where minimum hysteresis is important.
The narrow seal design provides a low friction incomparison to seals in a MIL-G-5514F/AS4716 groovewidth. The use of metallic expanders allows for a broadertemperature range and improves the chemical resistanceof the assembly.
Advantages
- Very low friction- Wide temperature range- Narrow groove- Controlled leakage- Excellent chemical resistance- Low hysteresis- MIL-G-5514F/AS4716 diameters from -112 and up

Description
The TurconR Glyd RingR is a simple and reliable sealconsisting of a TurconR seal cap activated by an O-Ring.
TurconR
Glyd RingR
Figure 98 TurconR Glyd RingR
Method of Operation
A true slipper seal, the Glyd RingR relies on the O-Ringenergization to provide the sealing force at zero or lowpressure. As the pressure increases the Glyd RingR isenergized by the hydraulic pressure and is force againstthe sealing surface.
The Glyd RingR is made with a slight interference fit whichensures initial contact with the mating surface.
The geometry of the Glyd RingR allows the formation ofa lubricating hydro-dynamic oil film under the seal inreciprocating applications.
All piston versions of the Glyd RingR are supplied withnotches to prevent blow-by (see also Plus SealRII,page 50). In the case of rod versions, notches are anoption andmust be specified in the part number. See page86 ”Option Notches”.
Advantages
- Low friction- Low cost- Narrow groove- Design flexibility - adaptable for almost allgroove sizes
- Long service life- High operational reliability- Stick-slip free operation- Easy installation- Available for all diameters
Technical Data
Operatingpressure: 35 MPa (5000 psi)
Speed: up to 15 m/s (49.2 ft/s) withreciprocating movements
Temperaturerange: -54°C to +200°C
(-65°F to +390°F)(depending on elastomer material)
Clearance: As indicated on the enclosed datasheets

TurconR StepsealRK

Busak+ ShambanEdition April 2004
TurconR StepsealRK*For use with MIL-Standard Rod/Bore
Description
The sealing of piston rods places the highest demands onoperational safety and environmental protection inhydraulic engineering.
Rod sealing systems must exhibit no dynamic leakage tothe atmosphere under all operating conditions and mustbe completely leak tight when the machine is in a staticcondition.
Furthermore, they should achieve a high degree ofmechanical efficiency through low friction and be easy toinstall in small grooves. Costs and service life must meetthe high expectations of the operator.
The piston rod seal, TurconR StepsealRK, developed byShamban comes closest to satisfying these idealdemands. Already in use for several decades, this seal isstill a technically outstanding seal element due to thecontinuous innovative development of the design and ofthe TurconR materials.
With the introduction of the StepsealRK it became possibleto arrange several seals one behind the other, thusallowing tandem seal configurations to be created withoutany build-up of intermediate pressure.
The single-acting seal element is made of high-gradeTurconR materials with outstanding sliding and wearresistance properties. It is installed in grooves to Shambanstandards using an O-Ring as the energizing element.

Method of Operation
The sealing mechanism of the StepsealRK (Figure 103)is based on the hydrodynamic properties of the seal. Thespecially formed seal edge has a steep contact pressuregradient on the high pressure side and a shallow contactpressure gradient on the low pressure side. This ensuresthat the fluid film adhering to the piston rod is returned tothe high pressure chamber on the return stroke of the rod.This prevents themicro-fluid layer, that is carried out of thehigh pressure chamber when the piston rod is extended,from causing leaks.
This return delivery property prevents the build-up ofinterstage pressure normally associated with tandem sealconfigurations (Figure 104). Interstage pressure dependson the system pressure speed, the stroke length and thegroove design.

Design Instructions
In many applications, tandem unvented sealing systemsare required. Figure 105 shows such a tandemconfiguration utilizing the StepsealRK. The use of tandemStepsealR increases functional reliability.

Figure 105 TurconR StepsealRK in TandemConfiguration
In this configuration it must be noted that a sufficientlylarge space is designed between the seals to take thehydraulic fluid, as shown in Figure 123, page 104.
Depending on the application and the operating conditions,the combination of different materials offers an improvementin the sealing efficiency and the service life of the system, e.g.in hydraulic cylinders subject to high loads and under roughoperating conditions.
StepsealR K elements should always be used in combinationwith a double acting scraper to provide an optimum sealingeffect. The ExcluderR DC is well suited for suchapplications. For further details, please see ExcluderR andScraper section on page 104.

Figure 110 TurconR Roto Glyd RingR
The Roto Glyd RingR consists of a seal ring of high-gradeTurconR material activated by an O-Ring as an elasticenergizing element.
The contact surface profile of the seal ring is specificallydesigned for use under high pressures and at low slidingspeeds.
Depending on the profile cross-section of the seal, thecontact surface has one or two continuous machinedgrooves. These have the following functions:
- Improved seal efficiency by increasing the specificsurface load pressure against the sealed surface.
- Formation of lubricant reservoir and reduction infriction.
In order to improve the pressure activation of the O-Ring,the Roto Glyd RingR has notched end faces as standard.
The geometry which holds the O-Ring has a concaveform. This increases the contact surface and prevents theseal from turning with the shaft.

TurconR VarilipR
Description
Due to their elastomer sealing lip, standard radial shaftseals have only a limited application range with respect topressure, temperature, media and loads.
VarilipR shaft seals from Shamban extend this applicationrange by using modern TurconR materials developedspecially for rotational applications.
The VarilipR is characterized in particular by their lowfriction, which reduces heat build-up and permits higherrotary speeds, and therefore longer life.
The VarilipR shaft seal is dimensionally interchangeablewith the shaft seals to DIN 3760 and ISO 6194/1. Inchsizes are also available.
The minimal groove size required for VarilipR allows its useas a pressurized seal where the installation of a mechanicalshaft seal would not be possible due to space envelope limits.

SealingTurconR lip
Figure 113 TurconR VarilipR, Type A
Method of Operation
In contrast to conventional shaft seals, the VarilipR sealrequires no metallic spring to energize the sealing lip.
As can be seen from Figure 113, dynamic sealing isaffected by the radial load of the sealing lip against theshaft. Static sealing is affected by a press fit of themetalliccasing in the housing bore, and by an elastomeric flatgasket between metallic housing and TurconR sealing lip.
Technical Data
Operating pressure: up to 2 MPa (290 psi)
Speed: 40 m/s (131 ft/s)
Temperature range: -60°C to +200°C(-76°F to +390°F)
Media: Practically all fluids, chemicals andgases.
Application Limits
The limits for temperature, pressure and speed given inthis catalog cannot be fully exploited at the same time.
Furthermore, the lubrication properties of the media, heatdissipation of the hardware, and the condition of the shaftsurface, affects the application limits.
The following p x v values can be used as general guidelines:For shaft diameter from 30 mm (1.2 in) to 170 mm (6.7 in):up to 3 (MPa x m/s) with good lubricationup to 1.5 (MPa x m/s) with poor lubricationup to 10 (MPa x m/s) with very good cooling
For smaller shaft diameters, the values must be reduced.
TurconR VarilipR, Type A
Type A (Fig. 114) is a one-lip seal suitable for use instandard applications up to pmax = 0.5 MPa (73 psi)where a radial shaft seal would be unable to withstand thetemperature, friction, medium or poor lubrication. Type Aallows high- speed shafts with peripheral speeds of up to40 m/s (131 ft/s) to be sealed.

TurconR ExcluderR and Scraper
104
Busak+ Shamban Edition April 2004
Selection of the Scraper Element
Scraper is a general term applied to those configurationsinstalled in hydraulic cylinders for the purpose of scrapingcontamination from rods, or excluding contaminationfrom the hydraulic system. The term scraper is generallyused in reference to those geometries that, although theyprovide a scraping function, do not prevent ingression ofsmall particles into the system. Excluders, in addition toproviding a scraping function, also minimize theingression of small particles into the system, and act as asecondary seal.
It is important to consider the scraper selection as anelement of a sealing system. Despite the proper selectionof primary and secondary seals, if a scraper appropriatefor the application is not selected, the resulting migrationof contamination into a system can cause damage to wearrings, seals, and hardware components. Scrapers thusform part of a functional system, and therefore must beviewed in combination with seals.
In order to satisfy a variety of technical and economicdemands, Shamban has developed a complete range ofscrapers with optimized geometries made fromhigh-quality materials.
An axial notch can be added to the inner scraping lip ofa double-acting scraper thereby providing a path to ventany interstage pressure to the outside while still retainingthe double-acting scraping effect. (See Fig. 128)
For systems with extreme working conditions, a springenergized scraper like the VarisealRM2S ensures a widetemperature range and optimal chemical resistance.
The final choice of scraper type and material must alsotake account of the detailed information on the individualscraper type elements.
Please do not hesitate to contact your sales engineer forfurther information on specific applications and specialtechnical questions.
Note on Ordering
All multi-element standard seals in this catalog whichcontain a proprietary elastomer part such as the Plus SealR
are always supplied as complete seal sets. The supplyincludes the seal and matching elastomer energizingelement.
O-Ring activated seals and scrapers are normallysupplied without the elastomer in order to increase theflexibility of delivery and stocking.
Exceptions to the above may be determined with yourlocal Shamban sales engineer to find the most suitablesolution.
Older designs no longer contained in this catalognaturally continue to be available. For all new applicationswe recommend the use of the types and preferred sizeslisted in this catalog.
Other combinations of TurconR materials and specialdesigns can be developed and supplied for specialapplications in intermediate sizes up to 3000 mm (10 ft)diameter, provided there is sufficient demand. Sizes over3000 mm (10 ft) are available for specific designs.
Groove Distance
When installing scrapers in conjunction with rod sealswhere interstage pressure is a concern, we recommendthe following positioning:
- Distance between seal groove and scraper groove Lshould exceed groove depth x
- Oil reservoir to collect the oil to be returned as shownin Figure 123.

TurconR ExcluderRDC, Series E
Description
The TurconR ExcluderRDC, Series E consists of an uncut,dual scraping lip TurconR element energized by astandard O-Ring. This design is offered as a retrofit to theMS33675 military gland standard which previouslyutilized a cut, spring energized scraper design.
TurconR ExcluderR
Figure 125 TurconR ExcluderRDC, Series E
Method of Operation
This design addresses the two contamination pathsinherent in the DC Scraper Ring design. The scarf cut iseliminated, and the garter spring is replaced with anO-Ring. In effect, these two changes create a secondarysealing element. The outboard scraping lip minimizes theingression of water and contaminates, and equallyimportant, the inboard scraping lip will contain any fluidleakage that may pass the primary seal. This fluid willprovide lubrication for the sealing system, reducingfriction and extending the life of the sealing system.
Note, for diameters smaller than 25 mm (1 inch) a splitgroove is recommended.
Shamban offers other ExcluderR designs that have betterperformance under the above mentioned conditions. Forbest performance results, the MS33675 gland standardis not recommended. Also see the section ExcluderRDC,page 107.
Please contact your Shamban sales engineer for furtherinformation.

TurconR ExcluderRDC
Description
The design of the TurconR ExcluderRDC optimizes thedevice’s ability to exclude contamination without therestrictions and limitations of the MS33675 glanddimensions. The gland has been altered to accommodatea larger cross section O-Ring for better activation of thescraping lips.
TurconR ExcluderR
Figure 127 TurconR ExcluderRDC
Method of Operation
The wider groove, combined with a better support on thedownstream side of the ExcluderRDC, has resulted in a farmore reliable exclusion device than those utilizing theMS33675 gland standard. These changes have led towidespread acceptance of the ExcluderRDC as thestate-of-the-art exclusion device for aerospace applications.
Due to the heavy cross-section of the TurconR element onthe downstream side, the ExcluderRDC will accept asignificant back-pressure without being extruded out ofthe groove. If high back-pressure is expected, werecommend use of the ExcluderRDC with the axial notch.

TurciteR SlydringR / LuytexR SlydringR

Busak+ Shamban Edition April 2004
TurciteR SlydringR / LuytexR SlydringR
The purpose of the rings is to guide the piston and rod ofa working cylinder and to absorb the transverse forceswhich may occur. Metallic contact between the slidingparts of the cylinder must be prevented. Non-metallicSlydringR offer major benefits compared with thetraditional metallic bearings:
- Cost efficient.
- High load bearing capacity.
- Eliminates local stress concentrations.
- Very wear-resistant, long service life.
- Eliminates galling.
- Good friction characteristics.
- Damping of mechanical vibrations.
- Protection of the seal against ”dieseling”.
- Eliminates hydrodynamic problems in the guide system.
- Easy installation.
- Low maintenance costs.
Designs
Three different types of SlydringR materials are availabledepending upon application demands:
- Highly wear-resistant, low friction, specially modifiedTurciteRmaterials for low to medium loads - SlydringR.
- LuytexR fabric composite materials for high loads andtransverse forces - SlydringR.
- ZurconR. High modulus thermoplastics for high loads,temperature with long service life.
SlydringR for Aerospace Applications
In the past, due to the imposed limitations ofMIL-G-5514F/AS4716 and the minimum requiredclearance gaps necessary to minimize seal extrusion,SlydringR use has been limited. The use of SlydringR oftenrequires larger clearance gaps.
With the trend toward higher hydraulic system pressures,resulting in higher sideloads, the use of SlydringR becomesnecessary in order to protect primary seals and hardware.
Since no industry standard has been developed forSlydringR, we have a wide range of sizes available inpreformed rings.
SlydringR are provided as cut rings with an angle cut asstandard. For special applications, other cut types areavailable; consult your Shamban sales engineer.

Busak+ Shamban Edition April 2004
TurconR WedgpakR Face Seal
Description
The TurconRWedgpakR Face Seal is an adaptation of thetraditional WedgpakR design to maximize performancein face seal applications. It utilizes a triangular shapedTurconR delta ring energized by a uniquely shapedelastomer designed to maximize extrusion protectionunder abnormal clearance gap conditions.
TurconR delta ring
elastomer
p
Figure 136 TurconR WedgpakR Face Seal
Method of OperationIt is typical for face seal applications to experience impulsepressures and therefore abnormally high ”breathing”conditions in mating hardware. The TurconR delta ringuses the full depth of the seal groove to optimize theamount of material available and maximize extrusionprotection under worst case conditions. The specialshaped geometry of the elastomer provides a preloadunder low pressure conditions, and constantly forces theTurconR delta ring up against the clearance gap toprevent extrusion of the elastomer.
Advantages
- Excellent static sealing effect- Good extrusion protection- Easy installation
Technical Data
Operating pressure: 35 MPa (5000 psi)
Speed: Not applicable
Temperature range: -54°C to +200°C(-65°F to +390°F)(depending on elastomer material)
Clearance: Can exceed recommendations ofMIL-G-5514F/AS4716 dependentupon the combination of pressuresand clearance gaps
Media: Mineral oil-based hydraulic fluids,flame retardant hydraulic fluids,environmentally safe hydraulic fluids(bio-oils), Phosphate Ester, water andothers, depending on the elastomermaterial (see Table IV, page 16)
MaterialsSee Table I, page 12 and Table III, page 15.

Installation Instructions
General Comments
After choosing the right seal design, the second mostimportant issue is to install the seal without damaging it.
The following hardware characteristics should beconsidered at an early hardware design stage in order toensure damage free installation of seals.
Rod lead inchamfer
Seal groove radiusRounded to 0.3 mm max.
Bevelled ports Bore lead-in chamfer
Installationpath free fromnicks andburrs
Installation tool to cover thread etc.Preferably made of plastic
Figure 141 Methods of Hardware Design to Prevent Seal Damage
- The installation path should be kept free of nicks, burrs,scratches, or any sharp edge that could damage theseal.
- Any tool used to install seals should be free of sharpedges. Screwdrivers are especially notorious fordamaging sealing lips and should not be used tohandle the seals.
- Tools made out of hard plasticlike Delrin or Nylon arepreferred.
- In situations where heat is required to soften andexpand the TurconR-seal components, submerse themfor a few minutes in hot oil or water (200 _F). Heatshould not be required to install elastomercomponents. Be sure to use compatible lubricant wheninstalling elastomer components.
- Application of a lubricant to surfaces of the seal andhardware reduces the force required to push the sealinto a difficult gland such as a solid O-Ring groove.
- Piston seals may be sized by freezing them prior toinstalling the piston in the bore. A typical situationwhere this is an advantage is on spool valve pistons.
- A lead-in chamfer on the end of the rod or bore helpsduring installation. The proper chamfer dimensions aregiven in the tables found later in this section. This isespecially important where seals are to be installedfacefirst towards the seal-lip into the gland.
- When seals must be installed across ports, the edges ofthe ports should be smooth and rounded.
- Design splines or keyways to fall on a smaller diameterthan the sealing surface or use a protective sleeve tocover them during installation as illustrated in Fig. 141.
- Avoid glands which require bending the seals duringinstallation. When seals must be stretched orcompressed into a difficult gland, be sure to use therecommended tooling described in Fig. 142-144 resizethe seals.
- Do not sideload the seals any more than is necessary.Avoid gland situations where a heavy rod or pistonbears against one side of the seal.
If you feel that your application poses a special problemwith installation, your Shamban sales engineer will bepleased to demonstrate installation of seals and scrapers.

For sizes where the TurconR seal ring is expanded morethan 15% (10% for the high filled materials TurconR T10and TurconR T29), a split groove is necessary.

Busak+ Shamban Edition April 2004
Procedure for installation of rod seals- Place the elastomer part into the groove- Compress the TurconR part into a kidney shape. Theseal must have no sharp bends (Figure 148)! Use arounded object like a pen to compress the TurconR
part.
Figure 148 Kidney-Shaped Deformation of the Seal Ring
Figure 149 Inserting the Seal Ring into the ClosedGroove
- After placing into the groove, form the seal into a ringagain by smoothing out the I.D. by hand.
- Finally, size the seal ring using a mandrel which shouldhave a chamfer of 10_ to 15_ over a length of approx.30 mm. (Figure 150).
The sizing mandrel should be made from a polymermaterial (e.g. polyamide) with good sliding characteristicsand high surface quality in order to avoid damage to theseals.
The piston rod itself can also be used for calibration,provided it has a sufficiently long lead-in chamfer.

Our sealing materials are produced free ofchlorofluorinated hydrocarbons and carcinogenicelements.
For Seals and Bearings used in the AerospaceIndustry, an ”A” must be specified in the 10thdigit. In special numbers, the ”A” will be in the 5th digitof the number. Customer-specific demands are indicatedand monitored with other characters in those positions.
Certificates of Approval
All manufacturing companies have ISO 9001/9002 certification and all marketing companies are certified or will be inthe near future.

Storage
(The notes in italics only apply to elastomeric sealingmaterials).
Seals and bearings are often stored as spare parts forprolonged periods. With a few basic simple precautions,the shelf life of these products can be considerablylengthened.
Seals and bearings should be stored where they are safefrom damage by external influences. Deformation, inparticular, should be avoided during storage.
Under the influence of various external factors e.g. heat,moisture, light, oxygen, ozone and as a result of contactwith liquid media, the properties of certain materials maychange. For example, deformation, ageing andweathering can cause deterioration of the originalmechanical and physical properties, depending on thematerial and shape of the parts.
Fundamental instructions on storage, cleaning andmaintenance of elastomer seal elements are described ininternational standards, such as:
Storage of rubber products: DIN 7716/BS 3F68: 1977
Maximum agelimitation: New seal storage spec.: ARP 5316
MIL-HDBK-695C (Pending on cancellation)MIL-STD-1523A (Cancelled)DIN 9088
The individual guidelines give several recommendationsfor the shelf life of elastomers, depending on the materialclasses.
The following guidelines should be observed to maintainthe optimum physical and chemical values of the parts:
Heat
The ideal temperature for storage is between+5_C/41_Fand +25_C/77_F. Direct contact with heaters should beavoided.
Moisture
Parts must be stored dry under normal atmosphericconditions (65% rel. moisture ±10).
Light
To ensure that the properties of the product aremaintained, elastomer seals should be stored to avoidexposure to ultra violet or neon light.
Oxygen
To protect elastomers from oxygen, they should be kept inthe original packaging or in airtight containers.
Weathering
To protect them against damage, seals and bearingsshould be kept in the original sealed packaging.
Ozone
Destruction of certain elastomeric sealing materials due toozone can be caused by the following machines andequipment:
- Mercury discharge lamps
- High voltage equipment
- Electric motors
- Electric spark sources or discharges
