Timken 30307 Tapered Roller Bearing

Description:

The Timken 30307 tapered roller bearing set is a matched single-row metric tapered roller bearing assembly consisting of the X30307M cone and Y30307M cup. Designed to support combined radial and axial loads, this bearing set provides precise shaft alignment, high load-carrying capacity, and dependable performance in demanding industrial applications. With a 35 mm bore, 80 mm outside diameter, and 22.75 mm overall width, it is commonly used in industrial gearboxes, wheel hubs, conveyors, electric motors, pumps, agricultural machinery, machine tools, and power transmission equipment.

Applications:

The Timken 30307 bearing set is engineered for applications requiring reliable performance under combined radial and thrust loads. Its separable cone-and-cup design simplifies installation, adjustment, and maintenance while ensuring accurate bearing preload. It is suitable for industrial gearboxes, wheel bearing assemblies, conveyor drives, electric motors, machine tools, pumps, agricultural equipment, and other heavy-duty rotating machinery.
