Decoding the designation

472 — the cup number in Timken’s inch tapered roller range. Base Number: 472.

B — flanged outer ring. The integral flange locates the cup axially against the housing face and squares the seal register in a through-bored housing. The plain 472 is the unflanged cup of the same raceway and a separate designation.

What these specs mean in practice

e Factor: 0.38. K Factor: 1.52. Y Factor: 1.56. The K factor fixes the ratio of radial to thrust capacity for the mounted pair, and at 1.52 this raceway angle carries substantial thrust alongside its radial load. G1 Factor: 38.8. G2 Factor: 27.8. Geometry Factor (Cg): 0.108, the constant Timken uses in its lubrication life adjustment factor. Case carburizing leaves a hard raceway over a tough core, which suits shock and misalignment loading.

Mounting data

Maximum Housing Fillet Radius: 0.03 in (0.8 mm) — the largest housing corner radius the cup back face clears. Housing Backing Shoulder Diameter, Frontface (Da): 4.56 in (115.82 mm). The flange seats on the housing face, so the flange sets the axial position of the cup.

Unit Quantity: 1 Pc. Cup only — one flanged outer ring, single row.
