Temperature limits

The permissible operating temperature for angular contact ball bearings can be limited by:
  • the dimensional stability of the bearing rings and balls
  • the cage
  • the lubricant
When temperatures outside the permissible range are expected, contact the SKF application engineering service.

Bearing rings and balls

SKF angular contact ball bearings undergo a special heat treatment. The bearings are heat stabilized up to at least 150 °C (300 °F).


Steel, brass or PEEK cages can be used at the same operating temperatures as the bearing rings and balls.


Temperature limits for SKF greases are provided under Lubrication.
When using lubricants not supplied by SKF, the temperature limits should be evaluated according to the SKF traffic light concept.
