FAQ

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

The suffix provides key specifications. 'DDU' indicates that the bearing has contact rubber seals on both sides, offering excellent protection against contamination. 'CM' signifies a special internal clearance designed for electric motor applications, which helps to reduce operational noise and vibration.

NS7S is a low-noise, low-torque grease primarily designed for standard operating temperatures in electric motors, typically up to around 120 deg C. For applications with consistently higher temperatures, a different grease type might be recommended. Always consult the manufacturer's datasheet for specific temperature limits.

Yes, while optimized for electric motors, a CM clearance bearing can be used in other applications. It has a slightly larger internal clearance than a 'CN' (Normal) bearing. This can be beneficial in applications with temperature differentials between the inner and outer rings or where press-fits are used. However, for precision applications like machine tool spindles, a different clearance class would be required.
