Timken 97900, a single cup for an imperial tapered roller bearing. The cup is the outer race: one tapered raceway, no rollers and no cage. Outside diameter 9.0000 in (228.60 mm), cup width 1.5000 in (38.10 mm).
97900 – Timken single-cup part number in the imperial 979xx cup range
97500 – the cone that runs against it, giving the 97500/97900 TS assembly
TS – tapered single, the assembly class this cup belongs to
A tapered roller bearing carries radial load and thrust in one direction through the contact angle between cone, rollers and cup. Cone and cup are separable and are matched as a pair, so raceway angle and roller path are common to the two halves of a published pairing. In the mounted 97500/97900 assembly the shaft bore is 5.0000 in, the housing bore is 9.0000 in and the assembled width is 2.1250 in.
Outside diameter: 9.0000 in (228.60 mm)
Cup width: 1.5000 in (38.10 mm)
Component: cup, outer race
Matching cone: Timken 97500
Assembly bore: 5.0000 in (127.00 mm)
Assembly width: 2.1250 in (53.975 mm)
Assembly class: TS, tapered single
Design units: imperial
1 Pc. Cup only. The matching cone is the Timken 97500.
The cup presses into the housing bore square to its seat, with the small end of the taper facing the cone. Bearing setting — end play or preload — is made up on assembly against the cone, so the cup seat depth and the shim or nut arrangement on the shaft together set the running condition.
The 97900 cup number is used across brands for the same envelope: SKF 97900, Koyo 97900, NTN 97900, Bower 97900. Load ratings published for the complete 97500/97900 assembly do not apply to a cup on its own.
