Temperature limits

The permissible operating temperature for needle roller thrust bearings can be limited by:
  • the dimensional stability of the bearing washers and rollers
  • the cage
  • the lubricant

Where temperatures outside the permissible range are expected, contact SKF.

Bearing washers and rollers

The bearings are heat stabilized up to at least 120 °C (250 °F).


Steel cages can be used at the same operating temperatures as the bearing washers and rollers. For temperature limits of polymer cages, refer to Polymer cages.


For temperature limits of SKF greases, refer to Selecting a suitable SKF grease.

When using lubricants not supplied by SKF, temperature limits should be evaluated according to the SKF traffic light concept.
