FAQ

Question?

What does the 'DDUCM' suffix mean on this NSK 6202 bearing?

The 'DDU' signifies that the bearing is fitted with two contact rubber seals, one on each side, providing excellent protection against contaminants and retaining grease. The 'CM' indicates a special internal clearance designed for electric motors, ensuring quiet operation and optimal performance under typical motor operating conditions.

Can I use a standard 6202-2RS bearing as a direct replacement for this 6202DDUCM?

While a standard 6202-2RS has the same dimensions and seal type, the 'CM' clearance is specific to electric motor applications. Using a bearing with standard clearance (CN) might result in higher operating noise or reduced lifespan in an electric motor. For non-motor applications, it is often interchangeable, but for its intended use, sticking with the 'CM' clearance is highly recommended.

What type of grease is used in this bearing, and does it require re-lubrication?

This bearing is lubricated for life from the factory with a high-quality grease suitable for a wide range of temperatures and speeds, indicated by the 'D NS7S5' code. The DDU seals are designed to retain this grease for the entire lifespan of the bearing, so no maintenance or re-lubrication is required.
