Temperature limits

The permissible operating temperature for four-point contact ball bearings can be limited by:
  • the dimensional stability of the bearing rings and balls
  • the cage
  • the lubricant
Where temperatures outside the permissible range are expected, contact SKF.

Bearing rings and balls

The bearings are heat stabilized up to at least 150 °C (300 °F).

Cages

Steel, brass or PEEK cages can be used at the same operating temperatures as the bearing rings and balls.

Lubricants

For temperature limits of SKF greases, refer to SKF greases.
When using lubricants not supplied by SKF, temperature limits should be evaluated according to the SKF traffic light concept.
