TIMKEN ROLLER BEARING 33890

Description:

The Timken 33890 is a single-row tapered roller bearing cone from the Timken 33800 Series. Designed for use with compatible bearing cups such as the 33822 or 33821 to form a complete tapered roller bearing assembly, it is engineered to support combined radial and axial loads while maintaining precise shaft alignment. The separable cone design simplifies installation and maintenance, making it ideal for industrial gearboxes, wheel hubs, conveyors, agricultural equipment, construction machinery, and general power transmission systems.

Applications:

The Timken 33890 tapered roller bearing cone is designed for applications requiring high load capacity and dependable performance under combined radial and thrust loads. When paired with a compatible Timken cup, it provides reliable operation in wheel bearing assemblies, industrial gearboxes, conveyor systems, machine tools, pumps, agricultural machinery, and other heavy-duty rotating equipment.
