Permissible speed

The speed ratings in the product table indicate:
  • the reference speed, which enables a quick assessment of the speed capabilities from a thermal frame of reference
  • the limiting speed, which is a mechanical limit that should not be exceeded unless the bearing design and the application are adapted for higher speeds

For additional information, refer to Operating temperature and speed.

Bearing pairs

For bearings arranged in pairs, the limiting speed should be reduced to approximately 80% of the value quoted for a single bearing.
