Timken 72225C Tapered Roller Bearing Assembly

Description:

The Timken 72225C bearing is a precision tapered roller bearing cone designed to support combined radial and axial loads in single row tapered roller bearing assemblies for heavy-duty rotating equipment. Commonly installed in industrial gearboxes, mining equipment, construction machinery, heavy-duty trailers, and power transmission systems where accurate shaft alignment and high load capacity are required. Maintenance teams, OEMs, and system integrators use this bearing cone for equipment repairs, bearing replacements, retrofit projects, and preventive maintenance to maximize reliability and bearing service life.

Applications:

The Timken 72225C tapered roller bearing cone is engineered for use with compatible Timken bearing cups in demanding industrial and mobile equipment. It is widely used in wheel-end assemblies, industrial drives, conveyors, heavy-duty axles, mining machinery, and other rotating equipment requiring dependable load distribution, reduced friction, and long-lasting bearing performance under continuous operating conditions.
