Timken 3520 Bearing Races Made In

Description:

The Timken 3520 is a single-row tapered roller bearing cup (outer ring) from the Timken 3500 Series. Designed for use with compatible Timken bearing cones such as the 3585, 3580, 3582, or 3583 to form a complete tapered roller bearing assembly, it is engineered to support combined radial and axial loads while maintaining precise shaft alignment. Its separable cup design simplifies installation, adjustment, and maintenance, making it ideal for automotive wheel hubs, trailers, industrial gearboxes, agricultural equipment, and general power transmission systems.

Applications:

The Timken 3520 bearing cup is designed for demanding applications requiring high load capacity and dependable performance under combined radial and thrust loads. When paired with a compatible Timken cone, it is commonly used in front wheel bearing assemblies, trailer axles, industrial gearboxes, conveyor systems, agricultural machinery, construction equipment, and other heavy-duty rotating machinery.
