Timken 354-3 inch tapered roller bearing cup. Bearing Type: Tapered roller bearing cup — the outer race of a single-row tapered roller bearing. Series: 354. Base Number: 354. Outside Diameter: 3.3465 in (85.001 mm). Overall Width: 0.748 in (18.999 mm). Rolling Elements: Tapered Roller. Number Of Rows: 1. Item Weight: 0.5 kg (1.1 lb).
354 — Timken base cup number, 3.3465 in outside diameter. The outside diameter is exactly 85 mm, so this cup drops into a metric housing bore as well as an inch one.
*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 354-3, 354 *3 and 354 #3.
e Factor: 0.31. Y Factor: 1.96. Geometry Factor (Cg): 0.0732. An e of 0.31 with a Y near 2 is a shallow-angle cup: capacity is weighted to the radial direction, and the calculation switches to its thrust-loaded form only once axial load passes about a third of the radial load.
Maximum fillet radius on the mating housing: 2.03 mm (0.08 in). Housing Backing Shoulder Diameter, frontface (Da): 81.03 mm (3.19 in). Housing Backing Shoulder Diameter, backface (Db): 76.96 mm (3.03 in).
Unit Quantity: 1 Pc. Cup only. Matching cones are the Timken 356 and 357.
354 is an industry-standard inch tapered roller bearing cup number. Koyo, NTN, NSK, SKF and BCA/Bower all build a 354 to the same boundary dimensions, and all interchange with this cup. Precision Class 3 is a Timken tolerance grade; a standard-class 354 from any maker fits the same envelope but holds a wider tolerance band.
