Timken 1985-90014 Precision Tapered Roller Bearing Assembly

Description:

The Timken 1985-90014 precision tapered roller bearing assembly is a factory-matched single-row bearing assembly designed to provide accurate shaft positioning while supporting combined radial and axial loads in high-precision industrial equipment. Commonly installed in machine tools, precision gearboxes, instrumentation equipment, and other industrial rotating machinery where consistent preload and running accuracy are critical. Maintenance teams, OEMs, and machine rebuilders use this precision bearing assembly for spindle repairs, equipment overhauls, precision retrofits, and replacement of matched bearing sets.

Applications:

The Timken 1985-90014 precision tapered roller bearing assembly is commonly used in precision machine tools, industrial gear drives, high-speed rotating equipment, and other applications requiring controlled internal clearance and reliable bearing performance. This factory-matched assembly consists of a Timken 1985 bearing cone and Timken 1931 bearing cup supplied as a precision matched set.
