Timken 3578 Tapered Roller Bearing Single Cone

Description:

The Timken 3578 is a single-row tapered roller bearing cone from the Timken 3500 Series. Designed for use with compatible bearing cups such as the Timken 3525 or 3526 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 cone design simplifies installation, adjustment, and maintenance, making it ideal for industrial gearboxes, wheel hubs, agricultural equipment, construction machinery, trailers, and general power transmission systems.

Applications:

The Timken 3578 tapered roller bearing cone is designed for demanding applications requiring high load capacity and reliable performance under combined radial and thrust loads. When paired with a compatible Timken cup, it is widely used in wheel bearing assemblies, industrial gearboxes, conveyor systems, machine tools, agricultural machinery, and other heavy-duty rotating equipment.
