TIMKEN 302097 9 KM1 TAPERED ROLLER BEARING SET CUPCONE

Description:

The Timken 30209 9/KM1 tapered roller bearing set is a matched single-row metric tapered roller bearing assembly consisting of a cone and cup. The "9/KM1" suffix identifies a factory-matched bearing set manufactured to Timken's specified mounting and preload tolerances. Designed to support combined radial and axial loads, this bearing set is widely used in industrial gearboxes, electric motors, conveyors, machine tools, pumps, and general industrial power transmission equipment where high load capacity and precise shaft alignment are required.

Applications:

The Timken 30209 9/KM1 bearing assembly is engineered for applications requiring reliable performance under combined radial and thrust loads. Its separable cone-and-cup design simplifies installation and maintenance while allowing accurate bearing adjustment. It is suitable for industrial gearboxes, conveyor drives, machine tools, electric motors, pumps, agricultural machinery, and other heavy-duty rotating equipment.
