FAQ

Question? What does the ‘DDUCM’ suffix mean on this NSK 6212 bearing?

The ‘DDU’ suffix indicates that the bearing is equipped with contact rubber seals on both sides. These seals provide excellent protection against dust and moisture while effectively retaining lubricant. The ‘CM’ suffix specifies a normal radial internal clearance that is specifically intended for use in electric motors, ensuring low noise and vibration levels.

Question? Is this bearing suitable for high-temperature applications?

The standard NSK 6212DDUCM bearing with its standard grease and rubber seals is typically rated for operating temperatures up to 110 deg C (230 deg F). For applications exceeding this temperature, a bearing with different seals (e.g., metal shields ZZ) and special high-temperature grease would be required.

Question? What are the proper mounting procedures for a bearing with contact seals like this one?

For a bearing of this size, it is crucial to use proper mounting tools like a bearing fitting tool kit or an induction heater. Never apply force directly to the outer ring if fitting onto a shaft, or to the inner ring if fitting into a housing. Applying force through the rolling elements can damage the raceways. Ensure the shaft and housing are clean and meet the specified tolerance for a correct fit.
