FAQ

What does the ‘DDUCM’ suffix mean for this NSK 6207 bearing?

The ‘DDU’ signifies that the bearing is equipped with contact seals on both sides, offering excellent protection against dust and moisture. The ‘CM’ indicates a specific radial internal clearance designed for electric motors, which helps manage thermal expansion during operation.

Is the NS7S5 grease suitable for high-temperature applications?

The NS7S5 grease (Kyodo Yushi Multemp PS No. 2) is a high-quality lithium-based grease with excellent low-noise properties, typically used in electric motor bearings. It has a standard operating temperature range, generally up to about 120 deg C. For applications exceeding this, a bearing with a different high-temperature grease would be required.

Can I use this bearing as a direct replacement for a standard 6207-2RS bearing?

Yes, in many cases. The 6207 is the standard size, and ‘DDU’ is NSK’s designation for what is commonly known as ‘2RS’ (Two Rubber Seals). However, the ‘CM’ clearance is specific. While it will physically fit, you should verify if the electric motor clearance is suitable for your specific non-motor application to ensure optimal performance and longevity.
