Temperature limits

The permissible operating temperature for cam followers can be limited by:

  • the dimensional stability of the bearing rings and rolling elements
  • the cage
  • the seals
  • the lubricant
When temperatures outside the permissible range are expected, contact the SKF application engineering service.

Bearing rings and rollers

SKF cam followers undergo a special heat treatment. The bearings are heat stabilized up to at least 140 °C (280 °F).

Cages

Steel cages can be used at the same operating temperatures as the bearing rings and rolling elements. For temperature limits of PA66 cages, refer to Cage materials.

Seals

The permissible operating temperature for seals depends on the material:

  • NBR seals:
    –40 to +100 °C (–40 to +210 °F)
    Temperatures up to 120 °C (250 °F) can be tolerated for brief periods.
  • PA66 sliding rings:
    –30 to +100 °C (–20 to +210 °F)

Lubricants

Temperature limits for greases used in SKF track runner bearings are provided in table 1. Temperature limits for other SKF greases are provided under Lubrication.
When using lubricants not supplied by SKF, the temperature limits should be evaluated according to the SKF traffic light concept.
