The Timken Company 14138A Tapered Roller Bearing Cone

Description:

The Timken 14138A tapered roller bearing cone is designed to support combined radial and axial loads while maintaining precise shaft alignment and reliable performance in demanding industrial applications. Commonly installed in industrial gearboxes, conveyors, agricultural machinery, construction equipment, machine tools, and heavy-duty power transmission systems requiring single-row tapered roller bearings. Maintenance teams, OEMs, and machine rebuilders use this bearing cone for equipment repairs, machine overhauls, OEM installations, and replacement of worn tapered roller bearing components.

Applications:

The Timken 14138A tapered roller bearing cone is commonly used in conveyor drive systems, industrial gearboxes, agricultural equipment, construction machinery, machine tools, and other rotating equipment where accurate shaft positioning, high radial and axial load capacity, and long bearing life are essential. The 14138A cone is designed for use with compatible Timken bearing cups, including the 14277 and 14299, depending on the application.
