The permissible operating temperature for double row deep groove ball bearings can be limited by:
- the dimensional stability of the bearing rings and balls
- the cage
- the lubricant
When temperatures outside the permissible range are expected, contact the SKF application engineering service.
Bearing rings and balls
SKF deep groove ball bearings undergo a special heat treatment. The bearings are heat stabilized up to at least 120 °C (250 °F).
For temperature limits of PA66 cages, refer to Cage materials.
Temperature limits for SKF greases are provided under Lubrication.
When using lubricants not supplied by SKF, the temperature limits should be evaluated according to the SKF traffic light concept.
