The permissible operating temperature for thrust ball bearings can be limited by:
- the dimensional stability of the bearing washers and balls
- the cage
- the seat washer(s)
- the lubricant
Where temperatures outside the permissible range are expected, contact the SKF application engineering service.
Bearing washers and balls
Depending on their size, washers and balls of SKF thrust ball bearings are heat stabilized up to:
- 125 °C (260 °F) where d ≤ 300 mm
- 150 °C (300 °F) where d > 300 mm
Steel and brass cages can be used at the same operating temperatures as the bearing washers and balls.
Seat washers are made of steel and can be used at the same operating temperatures as the bearing washers and balls.
