This permissible rotational speed is the permissible rotational speed that can be achieved based on the following assumptions.
For the allowable rotational speed under usage conditions that are different from the following, please refer to the "Precision Roller Bearing Catalog" or contact the manufacturer.

  • Use under conditions where an appropriate amount of recommended grease is filled, a sufficient break-in operation is performed, and heat generated is eliminated by such as cooling the outer housing
  • Use under constant preload
