6203 2RS/14 C3 PFI 14x40x12 Deep Groove Ball Bearing

Specialized 14 mm Bore Bearing for Industrial Drive Systems

The 6203 2RS/14 C3 PFI deep groove ball bearing is a specialized bearing designed for machinery utilizing a 14 mm shaft diameter while maintaining the external dimensions of the standard 6203 bearing series. This unique configuration makes it an ideal solution for industrial equipment, electric motors, pumps and mechanical drive systems requiring a non-standard bore size.

Equipped with double rubber seals and increased C3 internal clearance, the bearing provides excellent protection against contamination while ensuring reliable performance at higher operating temperatures and rotational speeds. Its deep groove ball bearing design delivers low friction, smooth operation and extended service life in demanding industrial environments.

FAQ

What is the difference between 6203 2RS/14 and a standard 6203 bearing?

The standard 6203 bearing has a 17 mm bore, while the 6203 2RS/14 version features a 14 mm bore with identical outer dimensions.

What is the purpose of C3 clearance?

C3 clearance provides additional internal space that compensates for thermal expansion during high-speed or high-temperature operation.

Is this bearing suitable for electric motors?

Yes. It is commonly used in electric motors, pumps, conveyors and industrial drive systems.

Does the bearing require additional lubrication?

No. The bearing is factory greased and ready for immediate installation.

Can this bearing support axial loads?

Yes. In addition to radial loads, it can accommodate moderate axial loads in both directions.
