The permissible operating temperature for Y-bearings can be limited by:
- the dimensional stability of the bearing rings and balls
- the cage
- the seals
- the lubricant
When temperatures outside the permissible range are expected, contact the SKF application engineering service.
Bearing rings and balls
Y-bearings undergo a special heat treatment. The bearing rings and balls are heat stabilized up to at least 150 °C (300 °F).
For temperature limits of PA66 cages, refer to Cage materials.
The permissible operating temperature for NBR seals is –40 to +100 °C (–40 to +210 °F). Temperatures up to 120 °C (250 °F) can be tolerated for brief periods.
When using lubricants not supplied by SKF, the temperature limits should be evaluated according to the SKF traffic light concept.
