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