Temperature limits

The permissible operating temperature for alignment needle roller bearings can be limited by:
  • the dimensional stability of the bearing rings and rollers
  • the cages
  • the seating rings
  • the lubricant
Where temperatures outside the permissible range are expected, contact SKF.

Bearing rings and rollers

SKF alignment needle roller bearings are heat stabilized up to at least 120 °C (250 °F).

Cages

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

Seating rings

The permissible operating temperature for seating rings is –30 to +100 °C (–20 to +210 °F).

Lubricants

For temperature limits of SKF greases, refer to Selecting a suitable SKF grease.
When using lubricants not supplied by SKF, temperature limits should be evaluated according to the SKF traffic light concept.
