The permissible operating temperature for cam followers can be limited by:
- the dimensional stability of the bearing rings and rollers
- the cage
- the seals
- the lubricant
Where temperatures outside the permissible range are expected, contact SKF.
Bearing rings and rollers
SKF cam followers are heat stabilized up to at least 140 °C (280 °F).
Steel cages can be used at the same operating temperatures as the bearing rings and rollers.
The permissible operating temperature for seals depends on the seal material:
NBR: –40 to +100 °C (–40 to +210 °F)
Temperatures up to 120 °C (250 °F) can be tolerated for brief periods.
- PA66 sliding rings: –30 to +100 °C (–20 to +210 °F)
When using lubricants not supplied by SKF, temperature limits should be evaluated according to the Traffic light concept.
