TIMKEN® TAPERED ROLLER BEARINGS Timken offers the most extensive line of tapered roller bearings in the world.Tapered bearings are uniquely designed to manage both thrust and radial loads on rotating shafts and in housings. We manufacture nearly 26,000 bearing combinations – in single, double and four-row configurations. Sizes range from an 8 mm (0.31496”) bore to a 2,222.5 mm (87.5”) outside diameter (OD). Customizedgeometries and engineered surfaces can be applied to these bearings to furtherenhance performance in demanding applications.

Single-Row BearingsSingle-row tapered roller bearingsconsist of four independent components:the cone (inner ring), the cup (outerring), the tapered rollers and the cage.The tapered angles allow the bearingsto handle a combination of radial andthrust loads.

Timken® single-row tapered bearings are commonly applied inwheels, transmissions, gear reductionunits and a wide array of rotatingindustrial equipment.

Single-row tapered roller bearingshave positive roller alignment thatensures true rolling motion andgenerates a “seating force” thatpushes the roller against the cone large rib. This seating force preventsthe rollers from skewing off apex,thereby keeping them positively alignedand located against the cone large rib.During assembly, tapered bearings canbe preset to required clearance (endplay) or preload conditions for optimumperformance.

TS bearings are the most widelyused design. TSF bearings are single-row tapered bearings that have flangedcups to facilitate axial location andaccurately align seats in through-boredhousings.

TSL bearings are similar to TSvarieties but feature DUO-FACE® PLUSseals pressed onto the outsidediameters of the cone ribs. TSUbearings are self-contained, unitizedassemblies that carry heavy radialloads and can manage thrust loads ineither direction.

Type TS Size range:7.937 mm – 1,701.8 mm bore(0.3125” – 67”)

Type TSF Size range:7.937 mm – 1,270 mm bore(0.3125” – 50”)

Type TSL Size range:19.505 mm – 68.262 mm bore(0.76791” – 2.6875”)

Type TSU Size range:30 mm – 45 mm bore(1.1811” – 1.7717”)

p r o d u c t s

Two-Row BearingsTimken tapered roller bearings areavailable in two-row designs. Two-row bearings are typically used inapplications such as heavy-duty geardrives, wheel hubs of heavy vehicles,coil conveyors, cranes and calenderrolls.

TNA bearings consist of doubleouter races and two single inner races.Internal bearing clearance is controlledby extending the front faces of theinner races so that they make contact.These bearings are pre-set duringmanufacturing and can be used at fixedor floating positions. Variations of theTNA bearing feature: chamfers, slots to provide lubrication through the shaft(Type TNASW), extended large ribs onthe inner races (Type TNASWE), andseal or stamped closures and/orflanged double outer races (TypeTNASWH).

Type TNASize range:19.05 mm – 406.4 mm bore(0.75” – 16”)

Type TNASW Size range:19.05 mm – 406.4 mm bore(0.75” – 16”)

4

Type TDOSize range:9.525 mm – 2,085 mm bore(0.375” – 82.0866”)

TDO bearings have a one-piece double outer ring and two single innerrings, and are used in either fixed orfloating positions. They are typicallysupplied with inner-ring spacers aspre-set assemblies. TDO bearings arefrequently chosen for applicationswhere overturning moments are a significant load component.

TDI bearings consist of a one-piecedouble inner ring and two single outerrings. They typically are suppliedcomplete with outer-race spacers inpre-set assemblies. A variation, theTDIT bearing, is available with atapered inner ring bore.

Type TQOSize range: 25.4 mm – 1,500 mm bore(1” – 59.0551”)

Type TQOWSize range:50.8 mm – 1,219.2 mm bore(2” – 48”)

Four-Row BearingsType TQO four-row tapered bearingsconsist of two pairs of directly mountedbearings, comprised of two doubleinner races, two single and one doubleouter race with one inner ring spacerand two outer ring spacers. Thesetypes are used on low- and medium-speed rolling mills and are applied tothe roll necks with a loose fit. When thefillet and/or filler rings do not alreadyhave lubrication slots, they areprovided in the faces of the bearinginner rings (type TQOW). The conespacers of these bearings arehardened to minimize face wear.

Type TQITSE Size range:50.8 mm – 1,219.2 mm bore(2” – 48”)

Type TQITS Size range:50.8 mm – 1,219.2 mm bore(2” – 48”)

Sealed roll neck bearings havespecially designed sealing arrange-ments. This allows the bearings toendure harsh environments by helpingto eliminate contamination from thebearing envelope, thereby extendingbearing life. All Timken sealed roll neckbearings have spiral bore grooves withblended radii to eliminate roll neckdamage.

Types TQITS and TQITSE consist oftwo pairs of indirectly mountedbearings, two single and one doublecone, four single cups and three cupspacers. Type TQITSE has an extensionto the large bore cone adjacent to theroll body. This not only provides ahardened, concentric and smoothsurface for radial lip seals, but alsoimproves roll neck rigidity by eliminatinga fillet ring. This feature allows thecenterline of the bearing to move closerto the roll body, and it also permitsshorter and less costly rolls. Theindirect mounting of both the TQITS andthe TQITSE increases the overalleffective spread of the bearing todeliver optimum stability and roll rigidity.

Sealed Roll Neck Bearings Size range:190.5 mm – 711.2 mm bore(7.5” – 28”)

Precision Tapered Roller BearingsSize range:7.937 mm – 315 mm bore(0.3125” – 12.4016”)

Some applications require a level ofprecision that cannot be achieved witha standard tapered roller bearing.Timken precision tapered rollerbearings promote and maintain theoperating accuracy required of today’smachine tool industry and variousrelated specialized markets. Precisionclass tapered roller bearings offermachine tool builders an economicaldesign solution that exceeds mostapplication needs for rotationalaccuracy and rigidity. Precision classesrange from Class 3 (C) to Class 000 (AA).

Spacer BearingAssembliesSpacer bearing assemblies speedbearing installation time by eliminatingthe need for bearing adjustment. Theycan be used with two-row and four-rowTimken tapered roller bearings to pre-set the bench lateral clearance (benchend play).

With the addition of spacers,machined to predetermined dimensionsand tolerances, many single-rowbearings (type TS) can be supplied as atwo-row, pre-set, ready-to-fit assembly.This principle is adopted in twostandard ranges of spacer assemblies:types 2S and SR. The concept also canbe applied to produce custom-madetwo-row bearings to suit specificapplications, for example, 2TS-TM and 2TS-DM.

Type 2SSize range:17.462 mm – 83.345 mm bore(0.6875” – 3.2813”)

Type 2TS-DMSize range:7.937 mm – 1,701.8 mm bore(0.3125“ – 67“)

Type SRSize range:50 mm – 200 mm bore (1.9685” – 7.874”)

Crossed Roller BearingsType TXRSize range: 203.2 mm – 1,879.6 mm bore(8” – 74”)

A crossed roller bearing is comprised of two sets of bearing races and rollersbrought together at right angles – withalternate rollers facing in oppositedirections – and within a section heightnot much greater than that of a singlebearing. The crossed roller design isideal for machine tool applications suchas vertical boring mills, vertical grindingmachines and other equipment.

TIMKEN® TORRINGTON® SPHERICAL ROLLER BEARINGSTimken® Torrington® spherical roller bearings feature all of the characteristics that have made Timken renowned – superior design, reliable performance andcomprehensive technical support. Our spherical bearings are designed to managehigh radial loads and perform consistently, even when misalignment, marginal lubrication, contamination, extreme speeds and critical application stresses are present.

Spherical Roller BearingsSize range: 25 mm – 1,500 mm bore(0.9843“ – 59.0551“)

Spherical roller bearings have matchingspherical surfaces on both rings androllers that enable the bearings tocompensate for modest misalignmentbetween a rotating shaft and thebearing housing. Spherical bearingshave high radial load capacity andaccommodate some combination ofradial and axial loads.

There are a number of sphericalbearing cage designs available that are offered in different styles forvarying combinations of loads andspeeds. For example, one designprovides an extra-close runningaccuracy for enhanced performance.Spherical roller bearings are used inapplications for power generation, pulpand paper mills, oilfield, mining andaggregate processing, wind turbines,gear drives and rolling mills.

Spherical Roller Bearing Special Features• Carburized components to lengthen

life in industrial machinery• Engineered surfaces to extend life• Special modification codes for

specific applications

Timken Torrington spherical bearingscan be ordered with several enhance-ments to extend life and improveperformance in specific applications.Carburized components offer highercompression stresses and resist shockloading. Large bearings often operatebelow the bearing's critical speed,causing the cage to push a non-rotatingroller across the raceways. This slidingaction breaks down lubrication film andcan ultimately damage the bearing.

Timken engineered surfaces protectbearing components from skidding

and sliding while withstanding small-particle contamination. In some cases,engineered surfaces can extendbearing life by up to five times standarddesigns. Bearings with engineeredsurfaces enhance life in paper androlling mills and other demandingapplications.

Special modification codes havebeen created for specific applicationsincluding W800 for vibrating mech-anisms and W906A for large papermachinery.

THRUST BEARINGSTimken® thrust bearings are designed specifically to manage thrust loads and provide high-shock-load resistance in industrial applications. These bearings provide high-speed performance and application flexibility. We manufacture thrustbearings in tapered, spherical, cylindrical, ball and needle configurations.

Timken® TaperedThrust BearingsThe TTHD bearing is designed for highthrust loads and heavy shock condi-tions. The bearing features an identicalpair of hardened and ground steelwashers with tapered raceways. Thetapered rollers are equally spaced by acage. TTHD bearings are used in slowto moderately high-speed applications,including oil well swivels, crane hooks,extruders and piercing mill thrustblocks.

Similar to the TTHD design, TTHDFL/TTVF and TTVS bearings combine thefeatures of tapered thrust and cylindri-cal roller bearings to offer the highestpossible capacity of any thrust bearingof its size. Both bearings employ a V-Flat design with the TTVS, providingself-aligning characteristics. In the V-Flat design, one washer is flat, whilethe second has a tapered racewaymatching the rollers. MostTTHDFL/TTVF and TTVS V-Flat bearingsizes utilize cages with hardened pinsthrough the center of the rollers. Thisallows for closer spacing of the rollersto maximize capacity.

The TTHDSV/TTSV andTTHDSX/TTSX tapered thrust bearingsare both full-roller complement designswithout conventional bores. They areprovided with a center insert forattachment purposes as well as for lifting. They offer the highest capacity,but at a somewhat reduced speedType TTHDFL/TTVF

Cylindrical Roller Bearings for Aerospace ApplicationsAll cylindrical roller bearingconfigurations, except RAA, provideprecision control of the rollers foroperation over a wide range of speedswith precision-ground, double-ribbedguide flanges on one ring. These rollerbearings are found in turbine enginemainshaft, transmission and gearboxapplications with high radial loads.

RF and RJ configurations work well with applications requiring axialposition control or limited thrustcapabilities in one direction. Underhigher loads and at higher speeds, theRJ configuration is easier to lubricatewith an oil jet onto the inner race. RUand RN are full-floating configurationsthat allow limited axial motion duringoperation. RN is less prone to slip orskid under lighter loads or varying loads

at high speeds. RU is easier to lubricateunder heavier loads.

RUS and RNH bearings are used inintegral designs where the rollers rundirectly on a hardened and ground shaftor housing. Performance characteristicsare similar to RU and RN. The RAAconfiguration has single-ribbed inner and outer rings and performs under lowspeeds or oscillating conditions. It hashigh guide flanges to accept some thrustin one direction.

Timken cylindrical roller bearingsachieve superior performance throughexceptional control of roller geometry.Rollers in all sizes over 3.5 mm arecontoured by crown blending foruniform stress distribution under load.The length is closely matched foruniform minimum clearance within the guide flanges to ensure optimumtracking at all speeds. These “square”rollers have superior ability to acceptthrust and misalignment. Rollers ofdiameter-to-length ratio less than onecan be supplied where it is critical tomaximize capacity and accommodateload conditions and OD restrictions.

Tapered Roller Bearings for Aerospace Applications

Timken tapered roller bearings are used in landing wheels on commercialairliners worldwide because Timken isthe brand of choice. Tapered rollerbearings can withstand highaccelerations and decelerations, heavyloads and a variety of temperature andenvironmental conditions.

Timken aircraft landing wheelbearings have been designated “2-629” (imperial) or “N-629” (metric),signifying that they are designed andmanufactured for the application,

achieving superior performancethrough tightened tolerances. Thetypical design is the single-row TS typethat can be set to a required clearanceor preload to optimize performance.

Tapered roller bearings also areused extensively in helicoptertransmissions and rotor supportsystems, where heavy combinedradial/axial/moment load requirementsare found. In addition to standardsingle-row configurations, double-row dissimilar series designs withasymmetric thrust capacity may besupplied with or without mountingflanges for unique applications.

To help extend bearing life in landingwheels and helicopter transmissions,Timken can apply engineered surfaces,including topographical enhancementsand coatings, that help prevent scuffingdamage and other surface-to-surfaceissues.
