Temperature limits

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
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).

Seals

The permissible operating temperature for PUR seals is –20 to +80 °C (–5 to +175 °F).

Typically, temperature peaks are at the seal lip.

Lubricants

Temperature limits for greases used in sealed double row full complement cylindrical roller bearings are provided in table 1. For temperature limits of other 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.
