Timken 14125W Tapered Roller Bearing Assembly

Description:

The Timken 14125W cone with 14276-B cup is a single-row tapered roller bearing assembly designed to support combined radial and axial loads while maintaining precise shaft alignment in demanding industrial applications. Commonly installed in industrial gearboxes, conveyors, agricultural machinery, construction equipment, and heavy-duty power transmission systems where a flanged cup design is required for accurate axial location. Maintenance teams, OEMs, and machine rebuilders use this bearing assembly for equipment repairs, machine overhauls, OEM installations, and replacement of worn tapered roller bearings.

Applications:

The Timken 14125W cone with 14276-B cup is commonly used in conveyor drive systems, industrial gearboxes, agricultural equipment, machine tools, construction machinery, and other rotating equipment where high radial and axial load capacity, reliable shaft positioning, and long bearing life are essential. The flanged cup design simplifies housing location and seal alignment in through-bored housings.
