FAQ

The 'CM' suffix indicates a specific radial internal clearance that is standard for deep groove ball bearings intended for electric motor applications. It also signifies that the bearing is subject to special noise level testing, ensuring quiet and smooth operation.

Yes, open-type bearings like the 6205CM with a steel cage are well-suited for high speeds. However, the maximum speed is dependent on the lubrication method (grease or oil) and the operating conditions. Always consult the manufacturer's datasheet for specific speed ratings.

As an open-type bearing, the NSK 6205CM is typically coated with a rust-preventative oil for transport and storage. It is not pre-packed with grease and requires proper lubrication according to the application's requirements upon installation.
