Timken 472B-3 flanged inch tapered roller bearing cup. Bearing Type: Tapered roller bearing cup with an integral outer-ring flange. Series: 472. Base Number: 472B. Outside Diameter: 4.7244 in (120 mm). Overall Width: 0.9542 in (24.237 mm). Outer Ring Flange Outside Diameter (D1): 4.9384 in (125.435 mm). Outer Ring Flange Width (C2): 0.2180 in (5.537 mm). Rolling Elements: Tapered Roller. Number Of Rows: 1. Item Weight: 1.4 kg (3.0 lb).
472 — Timken base cup number, 4.7244 in outside diameter. The 120 mm metric outside diameter is exact, which is why this cup drops into metric housings as well as inch ones.
B — flanged execution. The flange raises the outside diameter to 4.9384 in over a 0.2180 in band at one end, so the cup seats on the face of a through-bored housing instead of on an internal shoulder.
*3 — Timken Precision Class 3. Tighter running and mounting tolerance than standard class, giving lower running vibration and closer location in the housing bore. The same class is written 472B-3, 472B *3 and 472B #3.
e Factor: 0.38. K Factor: 1.52. Y Factor: 1.56. G1 Factor: 38.8. G2 Factor: 27.8. Geometry Factor (Cg): 0.108. A K of 1.52 is a moderately shallow roller angle: radial capacity leads, with a working thrust share in an opposed pair.
Maximum fillet radius on the mating housing: 0.8 mm (0.03 in). Housing Backing Shoulder Diameter, frontface (Da): 115.82 mm (4.56 in). The flange face sets axial position, so the housing bore can run straight through.
Unit Quantity: 1 Pc. Cup only. Matching cones are the Timken 480 and 484.
The flanged 472B is a Timken execution. The plain 472 and 472A cups share the 4.7244 in outside diameter and raceway and are built by several makers, but they locate on a housing shoulder rather than on a flange face, so they are related sizes rather than drop-in interchanges for a flanged seat. For a flanged 4.7244 in seat, Timken is the source.
