The permissible operating temperature for tapered roller bearings can be limited by:
- the dimensional stability of the bearing rings and rollers
- the cage
- the lubricant
Where temperatures outside the permissible range are expected, contact SKF.
Bearing rings and rollers
SKF tapered roller bearings are heat stabilized up to:
- D ≤ 160 mm → 120 °C (250 °F)
- D > 160 mm → 150 °C (300 °F)
Steel or PEEK cages can be used at the same operating temperatures as the bearing rings and rollers. For temperature limits of cages made of other polymer materials, refer to Cages.
For temperature limits of SKF greases, refer to Selecting a suitable grease.
When using lubricants not supplied by SKF, temperature limits should be evaluated according to the Traffic light concept.
