Decoding the designation

67835 — Timken inch cup number in the 67800 series. The number fixes the raceway angle and the outer envelope, and it pairs with the 67886 cone to make a complete TS single-row bearing.

Cup — the outer race. The rollers and the cage are carried on the cone, so a cup is supplied as a single hardened ring with one tapered raceway.

What these specs mean in practice

e Factor: 0.48. Y Factor: 1.26. Timken uses this pair to convert a combined radial and thrust duty into an equivalent radial load. A K factor of this order describes a steep-angle cup that carries a substantial thrust component alongside its radial load.

Geometry Factor (Cg): 0.131. This constant feeds the lubrication life adjustment factor a3l when the bearing life is calculated for a given oil film.

Case-carburized steel gives a hard raceway over a tough core, which is what lets an inch tapered roller bearing take shock loading without through-cracking.

Mounting data

Housing Backing Shoulder Diameter, Frontface (Da): 10.25 in (259.10 mm). Housing Backing Shoulder Diameter, Backface (Db): 10.08 in (256.03 mm). Maximum Housing Fillet Radius: 0.130 in (3.30 mm) — the largest fillet the housing may carry and still be cleared by the cup corner.

The cup seats in the housing bore with the large end of the raceway against the shoulder, and the cone runs on the shaft opposite it.
