Temperature limits

The permissible operating temperature for cylindrical roller bearings can be limited by:
  • the dimensional stability of the bearing rings and rollers
  • the cages
  • the seals
  • 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).

Cages

Steel or brass cages can be used at the same operating temperatures as the bearing rings and rollers.

Seals

The permissible operating temperature for HNBR seals is –40 to +140 °C (–40 to +285 °F).

Typically, temperature peaks are at the seal lip.

Lubricants

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.
