Timken 55433D Tapered Roller Bearing Assembly

Description:

The Timken 55433D Bearing Set with (2) Timken 55200 Cones is a TDO (Tapered Double Outer) tapered roller bearing assembly consisting of one 55433D double cup and two 55200 bearing cones. This matched assembly is engineered to support heavy combined radial and axial loads while providing exceptional rigidity and resistance to overturning moments. It is commonly used in industrial gearboxes, rolling mills, mining equipment, construction machinery, heavy-duty conveyors, and power transmission systems.

Applications:

The Timken 55200/55433D TDO Bearing Assembly is designed for demanding industrial applications requiring high load capacity, accurate shaft positioning, and long service life. Its double-row tapered roller bearing configuration provides a wide effective bearing spread, making it ideal for rolling mills, industrial gearboxes, mining and aggregate equipment, paper processing machinery, heavy-duty conveyors, and other industrial power transmission equipment where high radial and thrust loads are encountered.
