The permissible operating temperature for cam rollers can be limited by:
- the dimensional stability of the bearing rings and balls
- the cage
- the seals
- the lubricant
When temperatures outside the permissible range are expected, contact the SKF application engineering service.
Bearing rings and balls
SKF cam rollers undergo a special heat treatment. The bearings are heat stabilized up to at least:
- 120 °C (250 °F) for single row cam rollers
- 150 °C (300 °F) for double row cam rollers
CagesSteel cages can be used at the same operating temperatures as the bearing rings and balls. For temperature limits of PA66 cages, refer to Cage materials.
SealsThe permissible operating temperature for NBR seals is –40 to +100 °C (–40 to +210 °F). Temperatures up to 120 °C (250 °F) can be tolerated for brief periods.
LubricantsTemperature limits for greases used in SKF cam rollers 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.
