The permissible operating temperature for 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 ballsSKF deep groove ball bearings undergo a special heat treatment. The bearings are heat stabilized up to at least 120 °C (250 °F).
CagesSteel cages can be used at the same operating temperatures as the bearing rings and balls.
LubricantsTemperature limits for greases used in SKF deep groove ball bearings shielded on both sides are provided in table 1. Temperature limits for other 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.
