Timken 08231 Tapered Roller Bearing Cup Outer Race

Description:

The Timken 08231 tapered roller bearing cup is a precision outer race designed for single row tapered roller bearing assemblies that support combined radial and axial loads in industrial and mobile equipment. Commonly installed in automotive wheel hubs, agricultural machinery, industrial gearboxes, conveyors, and light-to-medium duty power transmission systems where accurate bearing alignment and dependable load handling are essential. Maintenance teams, OEMs, and system integrators use this bearing cup for equipment repairs, bearing replacements, retrofit projects, and preventive maintenance to maximize bearing performance and extend equipment service life.

Applications:

The Timken 08231 tapered roller bearing cup is engineered for use with the compatible Timken 08125 tapered roller bearing cone in TS (Tapered Single) bearing assemblies. It is widely used in wheel-end assemblies, agricultural equipment, industrial drives, conveyors, and general rotating machinery requiring reliable load distribution, reduced friction, and long service life under combined radial and thrust loading.
