Temperature limits

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

Bearing rings and rollers

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


The permissible operating temperature for PUR seals is –20 to +80 °C (–5 to +175 °F).


Temperature limits for greases used in sealed double row full complement cylindrical roller bearings are provided in table 1. Temperature limits for other 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.
