12303-2 Tapered Roller Bearing Single Cup <4 OD

This tapered roller bearing cup is the outer race component designed to work with a matching cone and roller assembly. The single-row design features a tapered raceway that allows the bearing to handle combined radial and thrust loads.

Tapered roller bearing cups are commonly used in automotive wheel hubs, industrial gearboxes, conveyor systems, and construction equipment where reliable performance under combined loading is required. Cups are typically press-fit into housings and must be properly matched with the correct cone for optimal operation.
