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
Bearing rings and balls
SKF cam rollers 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
The 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.
Typically, temperature peaks are at the seal lip.
