Timken 5203KC1 Double Row Angular Contact Ball Bearing

Description:

The Timken 5203KC1 Double Row Roller Bearing is a double-row angular contact ball bearing with a 17 mm bore, engineered to support combined radial and axial loads while delivering excellent rigidity, smooth operation, and long service life in industrial rotating equipment. The KC1 designation identifies a Conrad-type double-row angular contact bearing with C1 internal clearance for applications requiring precise shaft support and reduced internal play. It is commonly used in electric motors, pumps, compressors, industrial gearboxes, conveyors, agricultural machinery, and power transmission systems.

Applications:

The Timken 5203KC1 Bearing is designed for industrial applications requiring support for radial loads and moderate axial loads in both directions. Its double-row angular contact design provides greater rigidity than single-row bearings, making it ideal for electric motors, industrial gearboxes, pumps, compressors, conveyor systems, machine tools, agricultural equipment, and manufacturing machinery where dependable operation and extended bearing life are essential.
