FAQ

The 'CM' suffix indicates a specific internal clearance and raceway finish designed for electric motor applications. This results in lower noise and vibration levels compared to standard clearance bearings.

No, as an open-type bearing, the 6003CM is typically supplied with a light preservative oil to prevent corrosion. It must be lubricated with appropriate grease or oil according to the application's requirements before and during operation.

It is not recommended. Open bearings like the 6003CM offer no protection against contaminants. For dusty, dirty, or wet environments, a sealed (2RS) or shielded (ZZ) version of the 6003 bearing should be used to protect the internal components and extend service life.
