TIMKEN TAPERED ROLLER BEARING 432D

Description:

The Timken 432D is a double tapered roller bearing cup designed for use with compatible Timken bearing cones in heavy-duty industrial, automotive, and power transmission applications. Its TDO (Tapered Double Outer) configuration provides a wide effective bearing spread, making it well suited for applications subjected to high radial loads, axial loads in both directions, and overturning moments. Manufactured from premium bearing steel, it delivers excellent durability, load capacity, and long service life.

Applications:

The Timken 432D double cup is commonly used in industrial gearboxes, rolling mills, mining equipment, construction machinery, heavy-duty transmissions, axles, and other power transmission systems. It is designed to pair with compatible Timken bearing cones such as the 438, 437, or 435, depending on the bearing assembly configuration.
