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 Selecting a suitable grease.
When using lubricants not supplied by SKF, temperature limits should be evaluated according to the Traffic light concept.
