Temperature limits

The permissible operating temperature for INSOCOAT bearings can be limited by:
  • the dimensional stability of the bearing rings and rolling elements
  • the cage
  • the lubricant
Where temperatures outside the permissible range are expected, contact SKF.

Bearing rings and rolling elements

SKF INSOCOAT bearings are heat stabilized up to at least 150 °C (300 °F).


Steel or brass cages can be used at the same operating temperatures as the bearing rings and rolling elements. For temperature limits of PA66 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.
