The permissible operating temperature for cylindrical roller bearings can be limited by:
- the dimensional stability of the bearing rings and rollers
- the cage
- the lubricant
When temperatures outside the permissible range are expected, contact the SKF application engineering service.
Bearing rings and rollersSKF cylindrical roller bearings undergo a special heat treatment. The bearings are heat stabilized up to at least 150 °C (300 °F).
CagesSteel, brass or PEEK cages can be used at the same operating temperatures as the bearing rings and rollers. For temperature limits of cages made of other polymer materials, refer to Cage materials.
LubricantsTemperature 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.
