The permissible operating temperature for cylindrical roller bearings can be limited by:
- the dimensional stability of the bearing rings and rollers
- the seals
- the lubricant
When temperatures outside the permissible range are expected, contact the SKF application engineering service.
Bearing rings and rollers
SKF cylindrical roller bearings undergo a special heat treatment. The bearings are heat stabilized up to at least 150 °C (300 °F).
The permissible operating temperature for PUR seals is –20 to +80 °C (–5 to +175 °F).
When using lubricants not supplied by SKF, the temperature limits should be evaluated according to the SKF traffic light concept.
