A complete single-row tapered roller bearing set from Timken: the L305649-3 cone (inner ring with rollers and cage) together with its matching L305610-3 cup (outer race). Bore is 2 inches, cup outside diameter 3-3/16 inches. The -3 suffix on both halves is Timken Class 3 precision, a tighter tolerance grade than standard. Sets in this size are used in gearboxes, spindles, wheel and hub positions, pump and pinion shafts — anywhere a bearing must take a heavy radial load together with thrust in one direction.
L305649 — the cone (inner ring, rollers and cage).
L305610 — the cup (outer race) designed to run with that cone.
-3 — Timken Class 3 precision on each part; also written *3 or #3.
Cone and cup are designed as a pair; the pairing sets the contact angle, the load ratings and the internal setting. Class 3 precision tightens bore, OD and running accuracy beyond standard class, for shaft positions that need accurate location or smooth running at speed, and keeps the standard mounting dimensions. A single-row tapered roller bearing takes thrust in one direction, so shafts normally use two opposed bearings, which also allows the assembly to be set to a specified end play or preload.
Bore (cone): 2 inch.
Outside diameter (cup): 3-3/16 inch.
Cone width: 0.7185 in.
Cup width: 0.5625 in.
Cone backface “to clear” radius: 0.03 in.
Cup backface “to clear” radius: 0.05 in.
Component: matched cone and cup set.
Precision: Timken Class 3.
Rows: single.
Bearing type: tapered roller.
Bearing material: High Alloy Steel.
Design units: inch.
One complete set: one L305649-3 cone and one L305610-3 cup, matched.
The set is referenced as L305649/L305610, L305649-L305610 and L305649/10, with the -3 suffix denoting Class 3. The standard-class L305649/L305610 without the -3 is a looser tolerance grade. Timken part numbers carrying a -90xxx suffix are complete factory assemblies.
