Timken 48120-3 inch tapered roller bearing cup. Bearing Type: Tapered roller bearing cup — the outer race of a single-row tapered roller bearing. Series: 481. Base Number: 48120. Outside Diameter: 6.3750 in (161.925 mm). Overall Width: 1.0625 in (26.988 mm). Rolling Elements: Tapered Roller. Number Of Rows: 1. Item Weight: 2.30 kg (5.2 lb).
48120 — Timken base cup number in the 481 inch series, 6.3750 in outside diameter.
*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 48120-3, 48120 *3 and 48120 #3.
e Factor: 0.51. Y Factor: 1.19. Geometry Factor (Cg): 0.156. An e of 0.51 is a steep raceway angle, so the cup holds its radial rating up to a large thrust component before the rating calculation changes form.
Maximum fillet radius on the mating housing: 3.30 mm (0.130 in). Housing Backing Shoulder Diameter, frontface (Da): 156.00 mm (6.16 in). Housing Backing Shoulder Diameter, backface (Db): 146.05 mm (5.75 in).
Unit Quantity: 1 Pc. Cup only. The matching cone is the Timken 48190.
48120 is an industry-standard inch tapered roller bearing cup number. Koyo, NTN, NSK, SKF and BCA/Bower all build a 48120 to the same boundary dimensions, and all interchange with this cup. Precision Class 3 is a Timken tolerance grade; a standard-class 48120 from any maker fits the same envelope but holds a wider tolerance band.
