TIMKEN TAPERED ROLLER BEARINGS TYPES AND CAGES

SINGLE ROW BEARINGS

TS  SINGLE ROW This is the basic and the most widely used type of tapered roller bearing. It consists of the inner ring assembly and the outer ring. It is usually fitted as one of an opposing pair. During equipment assembly, single row bearings can be set to the required clearance endplay or preload condition to optimize performance

TSF  SINGLE ROW, WITH FLANGED OUTER RING

The TSF type is a variation on the basic single row bearing. TSF bearings have a flanged outer ring to facilitate axial location and accurately aligned seats in a through bored housing

DOUBLE ROW BEARINGS

TDO  DOUBLE OUTER RING

This has a one piece double outer ring and two single inner rings. It is usually supplied complete with an inner ring spacer as a pre set assembly. This configuration gives a wide effective bearing spread and is frequently chosen for applications where overturning moments are a significant load component. TDO bearings can be used in fixed (locating) positions or allowed to float in the housing bore, for example, to compensate for shaft expansion. TDOCD outer rings also are available in most sizes. These outer rings have holes in the O.D. that permit the use of pins to prevent outer ring rotation in the housing

TDI  DOUBLE INNER RING TDIT  DOUBLE INNER RING WITH TAPERED BORE

Both comprise a one-piece double inner ring and two single outer rings. They are usually supplied complete with an outer ring spacer as a pre-set assembly. TDI and TDIT bearings can be used at fixed locating positions on rotating shaft applications. For rotating housing applications, the double inner ring of type TDI can be used to float on the stationary shaft. Type TDIT has a tapered bore to facilitate removal when an interference fit is essential, yet regular removal is required.
