FAQ

What does the 'CM' suffix mean for the NSK 6219CM bearing?

The 'CM' suffix denotes a specific set of features for deep groove ball bearings. It signifies a brass cage ('M') and a special radial internal clearance ('C') suitable for applications like electric motors that require specific noise levels and performance characteristics.

The NSK 6219CM with its brass cage has better high-temperature performance than a bearing with a standard steel cage. As an open bearing, its temperature limit is primarily determined by the lubricant used. For specific temperature ratings, consult the NSK engineering catalog and your lubrication supplier.

Yes, in many cases. The 6219CM has a C3 equivalent clearance, which is greater than standard CN clearance. This is often beneficial in applications with temperature gradients or press fits. However, if your application requires a specific clearance (e.g., CN or C2), using a C3 bearing could affect performance. Always check your machine's requirements.
