Timken 82950 Roller Bearing Cup Outer Ring Assembly

Description:

The Timken 82950 roller bearing cup is a precision outer race designed for single row tapered roller bearing assemblies that support combined radial and axial loads in heavy-duty rotating equipment. Commonly installed in industrial gearboxes, mining equipment, construction machinery, heavy-duty trailers, and power transmission systems where accurate bearing alignment and high load capacity 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 equipment reliability.

Applications:

The Timken 82950 roller bearing cup is engineered for use with compatible Timken tapered roller bearing cones in demanding industrial and mobile equipment. It is widely used in wheel-end assemblies, steel mills, heavy-duty axles, industrial drives, conveyors, mining machinery, and other rotating equipment requiring dependable load distribution, reduced friction, and extended bearing service life under continuous operating conditions. The cup is commonly paired with the Timken 82576 bearing cone.
