Timken 28580 Cone w 28521 Cup

Description:

The Timken 28580/28521 tapered roller bearing set is a matched single-row tapered roller bearing assembly consisting of the 28580 cone and 28521 cup. It is designed to support combined radial and axial loads in heavy-duty rotating equipment. Commonly installed in industrial gearboxes, conveyor systems, mining machinery, agricultural equipment, wheel hubs, and power transmission systems, this bearing set is used by maintenance professionals, OEMs, and rebuild specialists for equipment replacement, preventive maintenance, and machinery overhauls.

Applications:

The Timken 28580/28521 bearing set provides precise shaft alignment, reduced friction, and high load-carrying capacity under combined radial and thrust loads. Its separable cone-and-cup design simplifies installation and maintenance, making it suitable for industrial gearboxes, conveyor drives, axle assemblies, machine tools, agricultural machinery, mining equipment, and material handling systems operating in demanding environments.
