Timken 55433D Tapered Roller Bearing Cup Assembly

Description:

The Timken 55433D Double Cup is a TDO (Tapered Double Outer) tapered roller bearing double cup designed for use with compatible Timken tapered roller bearing cones to support heavy combined radial and axial loads. Its double-cup configuration provides a wide effective bearing spread, making it ideal for applications subjected to significant overturning moments. It is commonly installed in industrial gearboxes, rolling mills, mining equipment, construction machinery, paper processing machinery, and heavy-duty power transmission systems.

Applications:

The Timken 55433D Double Cup is engineered for demanding industrial applications requiring high load capacity, excellent shaft rigidity, and precise alignment. It is designed for TDO bearing assemblies and is commonly paired with Timken 55194, 55200, 55206C, and other compatible bearing cones. Typical applications include rolling mills, industrial gearboxes, mining and aggregate equipment, construction machinery, paper mills, and heavy-duty power transmission equipment.
