TIMKEN 29520 BEARING

Description:

The Timken 29520 tapered roller bearing cup is a single-row tapered roller bearing outer race (cup) designed for use with a compatible Timken tapered roller bearing cone to support combined radial and axial loads. It is commonly installed in industrial gearboxes, conveyor systems, mining machinery, agricultural equipment, wheel hubs, and heavy-duty power transmission systems requiring precise shaft alignment and high load capacity. Maintenance technicians, OEMs, and rebuild specialists use this bearing cup for equipment replacement, preventive maintenance, and machinery rebuilds.

Applications:

The Timken 29520 tapered roller bearing cup is engineered to operate with compatible Timken cones such as the 29585 and 29590, providing accurate shaft positioning, reduced friction, and reliable performance under combined radial and thrust loads. Its separable cup design simplifies installation and maintenance, making it suitable for industrial gearboxes, conveyor drives, axle assemblies, machine tools, mining equipment, agricultural machinery, and material handling systems operating in demanding environments.
