Temperature limits

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
Where temperatures outside the permissible range are expected, contact SKF.

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

Cages

Steel cages can be used at the same operating temperatures as the bearing rings and balls. For temperature limits of PA66 cages, refer to Cages.

Seals

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.

Lubricants

Temperature limits for greases used in SKF cam rollers are provided in table 1. For temperature limits of other SKF greases, refer to Selecting a suitable grease.
When using lubricants not supplied by SKF, temperature limits should be evaluated according to the Traffic light concept.
