The permissible operating temperature for needle roller and cage assemblies can be limited by:
- the dimensional stability of the rollers
- the cages
- the lubricant
Where temperatures outside the permissible range are expected, contact SKF.
The assemblies are heat stabilized up to 120 °C (250 °F).
Steel cages can be used at the same operating temperatures as the bearing rollers. For temperature limits of polymer 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.
