The permissible operating temperature for INSOCOAT bearings can be limited by:
- the dimensional stability of the bearing rings and rolling elements
- the cage
- the lubricant
Where temperatures outside the permissible range are expected, contact SKF.
Bearing rings and rolling elements
SKF INSOCOAT bearings are heat stabilized up to at least:
- 120 °C (250 °F) for deep groove ball bearings
- 150 °C (300 °F) for cylindrical roller bearings
Steel or brass cages can be used at the same operating temperatures as the bearing rings and rolling elements. For temperature limits of PA66 cages, refer to Cage materials.
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.
