Timken 31521-20024 Tapered Roller Bearing 58x76x24mm

Description:

The Timken 31521-20024 tapered roller bearing set is a matched single-row tapered roller bearing assembly consisting of the 31521 cone and 20024 (31520) cup. Designed to support combined radial and axial loads, this bearing set provides precise shaft alignment, high load-carrying capacity, and reliable performance in demanding industrial applications. It is commonly used in industrial gearboxes, conveyors, agricultural equipment, machine tools, wheel hubs, and power transmission systems where durability and efficient operation are essential. Note that the dimensions "58 × 76 × 24 mm" do not correspond to the standard Timken 31521-20024 bearing dimensions.

Applications:

The Timken 31521-20024 bearing set is engineered for applications requiring dependable 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, conveyor drives, axle assemblies, agricultural machinery, machine tools, and other heavy-duty rotating equipment.
