TIMKEN,99102CD,DOUBLE ROLLER BEARING CUP

Description:

The Timken 99102CD is a precision double tapered roller bearing cup designed for TDO (Tapered Double Outer) bearing assemblies that support exceptionally high combined radial and axial loads while providing a wide effective bearing spread for improved rigidity. Manufactured from premium through-hardened bearing steel, the double cup is engineered for heavy-duty industrial applications where resistance to overturning moments, precise shaft positioning, and long service life are essential. Commonly used in rolling mills, mining equipment, industrial gear drives, marine propulsion systems, paper mills, and heavy processing machinery, the Timken 99102CD is widely selected by maintenance teams, OEMs, and system integrators for equipment repairs, bearing replacements, retrofit projects, and preventive maintenance.

Applications:

The Timken 99102CD double tapered roller bearing cup is designed for use with compatible Timken double-row tapered roller bearing cones, such as the 99600 cone, to form a complete TDO bearing assembly. Its wide effective bearing spread makes it ideal for applications subjected to heavy radial loads, axial loads in both directions, and significant overturning moments, including rolling mills, mining conveyors, steel processing equipment, marine drives, industrial gearboxes, and other heavy-duty rotating machinery.
