Temperature limits

The permissible operating temperature for hybrid cylindrical roller bearings can be limited by:
  • the dimensional stability of the bearing rings
  • the cages
  • the lubricant
When temperatures outside the permissible range are expected, contact the SKF application engineering service.

Bearing rings

The rings of SKF hybrid cylindrical roller bearings undergo a special heat treatment. The bearing rings are heat stabilized up to at least 150 °C (300 °F).
On request, SKF can supply hybrid cylindrical roller bearings with rings stabilized for operating temperatures up to 300 °C (570 °F).


Brass or PEEK cages can be used at the same operating temperatures as the bearing rings of standard hybrid bearings. For temperature limits of other polymer cages, refer to Cage materials.


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.
