TIMKEN 27689 -27620-B TAPERED ROLLER BEARINGS 722673-01380

Description:

The Timken 27689-27620-B tapered roller bearing set is a matched single-row TSF (Tapered Single with Flange) bearing assembly consisting of the 27689 cone and the 27620-B flanged cup. It is engineered to support combined radial and axial loads while providing precise shaft positioning in heavy-duty rotating equipment. The flanged cup design provides positive axial location and is commonly used in industrial gearboxes, conveyors, mining equipment, rolling mills, agricultural machinery, and heavy-duty power transmission systems.

Applications:

The Timken 27689-27620-B bearing set is designed for applications requiring high load capacity, low friction, and reliable operation under combined radial and thrust loads. Its separable cone-and-cup construction simplifies installation and maintenance, while the flanged outer cup improves housing location and retention. It is ideal for industrial gearboxes, conveyor drives, axle assemblies, mining machinery, material handling equipment, and other demanding industrial applications.
