The Timken Company T151W Tapered Roller Thrust Bearing

Description:

The Timken T151W tapered thrust roller bearing is used to support heavy unidirectional axial loads in industrial power transmission systems, gear drives, and heavy-duty machinery. Commonly installed in industrial gearboxes, rolling mills, machine tools, mining equipment, and construction machinery where high thrust load capacity and precise axial shaft positioning are required. Maintenance teams, OEMs, and system integrators use this bearing for replacement, repair, retrofit, and equipment overhaul to restore dependable thrust load performance and extend equipment service life.

Applications:

The Timken T151W is a single-direction tapered thrust roller bearing featuring a retainer with oil holes (W designation) to improve lubrication under demanding operating conditions. It is widely used in heavy industrial machinery, steel processing equipment, mining systems, power transmission assemblies, presses, and other applications requiring exceptional axial load capacity, reduced friction, and long operating life.
