The Timken Company 99102CD Double Roller Bearing Cup

The Timken 99102CD double tapered roller bearing cup is a precision TDO (double outer) cup designed to pair with Timken double-row cones, such as the 99600 cone, to form a complete TDO bearing assembly that supports very high combined radial and axial loads with a wide effective bearing spread for improved rigidity. Made from through-hardened bearing steel, it's built for heavy-duty industrial applications requiring resistance to overturning moments, precise shaft positioning, and long service life.
