Timken 5306W-C1 Angular Contact Ball Bearing

Description:

The Timken Fafnir 5306W C1 Bearing is a double-row angular contact ball bearing designed to support combined radial and axial loads in both directions while providing high rigidity, accurate shaft positioning, and long service life. Featuring a 30° contact angle and C1 internal clearance, it is well suited for demanding industrial applications requiring precise alignment and dependable performance. It is commonly installed in electric motors, industrial gearboxes, pumps, compressors, conveyors, machine tools, and power transmission systems.

Applications:

The Timken 5306W C1 Bearing is engineered for industrial equipment requiring simultaneous radial and bidirectional axial load support. Its double-row angular contact design provides greater rigidity than single-row bearings, making it ideal for electric motors, pumps, compressors, industrial gearboxes, conveyor systems, agricultural machinery, and manufacturing equipment where smooth operation and extended bearing life are essential.
