TIMKEN 29622D TAPERED ROLLER BEARING CUP

Description:

The Timken 29622D tapered roller bearing cup is a double tapered cup (TDO) designed for use with two compatible tapered roller bearing cones to support heavy combined radial and axial loads while resisting overturning moments. Its double-cup configuration provides a wide effective bearing spread, making it suitable for fixed or floating bearing arrangements in demanding industrial equipment. It is commonly used in industrial gearboxes, rolling mills, mining machinery, conveyors, paper mills, and heavy-duty power transmission systems.

Applications:

The Timken 29622D double tapered roller bearing cup is engineered for applications requiring high rigidity, precise shaft positioning, and the ability to withstand heavy radial, axial, and moment loads. It is designed to operate with compatible Timken cones in TDO bearing assemblies and is widely used in industrial gearboxes, steel mills, mining equipment, paper processing machinery, material handling systems, and other heavy industrial rotating equipment.
