The permissible operating temperature for cylindrical roller bearings can be limited by:
- the dimensional stability of the bearing rings and rollers
- the cages
- the lubricant
Where temperatures outside the permissible range are expected, contact SKF.
Bearing rings and rollers
SKF cylindrical roller bearings are heat stabilized up to 150 °C (300 °F).
Steel or brass cages can be used at the same operating temperatures as the bearing rings and rollers.
The permissible operating temperature for HNBR seals is –40 to +140 °C (–40 to +285 °F).
Typically, temperature peaks are at the seal lip.
For temperature limits of SKF greases, refer to Selecting a suitable SKF grease.
When using lubricants not supplied by SKF, temperature limits should be evaluated according to the SKF traffic light concept.
