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 Selecting a suitable SKF grease.
When using lubricants not supplied by SKF, temperature limits should be evaluated according to the SKF traffic light concept.
