TIMKEN 27689 TAPERED ROLLER BEARING, SINGLE CONE, PRECISION TOLERANCE

Description:

The Timken 27689 tapered roller bearing cone is a single-row precision tapered roller bearing cone designed for use with a matching Timken bearing cup to support combined radial and axial loads. Manufactured to precision tolerances, it is commonly used in industrial gearboxes, conveyors, mining machinery, rolling mills, heavy equipment, and power transmission systems requiring accurate shaft positioning and high load capacity. Maintenance technicians, OEMs, and equipment rebuild specialists use this bearing cone for machinery replacement and overhaul applications.

Applications:

The Timken 27689 tapered roller bearing cone is engineered to provide reliable performance under heavy radial and thrust loads when paired with a compatible Timken bearing cup such as the 27620. Its separable cone design allows for easy installation, adjustment, and maintenance while ensuring precise shaft alignment. It is ideal for industrial gearboxes, conveyor drives, axle assemblies, mining equipment, agricultural machinery, machine tools, and other heavy-duty rotating equipment.
