FAQ

Question? What does the 'DDUCM' suffix mean for this NSK bearing?

The 'DDU' suffix indicates that the bearing is equipped with contact rubber seals on both sides, providing excellent protection against contaminants and retaining grease. The 'CM' suffix denotes a special radial internal clearance specifically designed for electric motor applications, ensuring quiet and efficient operation.

NS7S refers to NS Hi-Lube grease, a standard polyurea-based grease. It has a good operating temperature range, typically from -40 deg C to +150 deg C. While suitable for many standard and electric motor applications, for extreme high-temperature environments, a different grease type might be recommended. Always check your application's specific requirements.

Yes, in many cases, a DDU sealed bearing can replace a ZZ shielded or an open bearing of the same size (6212). The DDU seals offer superior protection against dust and moisture. However, be aware that contact seals (DDU) have slightly higher friction and lower speed limits than non-contact shields (ZZ) or open bearings. For very high-speed applications, this should be taken into consideration.
