TIMKEN DOUBLE BEARING CUP 33462D

Description:

The Timken 33462D is a double tapered roller bearing cup (double outer ring) designed for use with compatible Timken double cone assemblies to create a complete TDO (Tapered Double Outer) bearing arrangement. Its double-cup configuration provides a wide effective bearing spread for superior support of heavy combined radial and axial loads, making it ideal for applications subject to overturning moments. It is commonly used in industrial gearboxes, rolling mills, mining equipment, paper mills, construction machinery, and heavy-duty power transmission systems.

Applications:

The Timken 33462D double bearing cup is engineered for heavy-duty industrial applications requiring high rigidity, excellent shaft stability, and long service life. When paired with compatible Timken double cones such as 33225, 33261, 33262, 33281, or 33287, it forms a complete TDO bearing assembly suitable for gear drives, rolling mills, mining machinery, conveyors, and other equipment operating under high radial and thrust loads.
