Deep Groove Ball Bearings Permissible Speed


The speed ratings in the data 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.

SKF recommends oil lubrication for bearings with a ring centred cage (designation suffix MA or MB). When these bearings are grease lubricated the ndm value is limited to 250 000 mm/min.
