Double Row Angular Contact Ball Bearings Temperature limits
Temperature limits
The permissible operating temperature for angular contact ball bearings can be limited by:
- the dimensional stability of the bearing rings and balls
- the cage
- the seals
- the lubricant
Where temperatures outside the permissible range are expected, contact Lily.
Bearing rings and balls
The bearings are heat stabilized up to at least 150 °C (300 °F).
Cages
Steel or brass cages can be used at the same operating temperatures as the bearing rings and balls. For temperature limits of cages made of other polymer materials.
Seals
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.
Typically, temperature peaks are at the seal lip.
Lubricants
emperature limits for greases used in sealed Lily angular contact ball bearings are provided in(table 1)
When using lubricants not supplied by Lily, temperature limits should be evaluated according to the Lily traffic light concept.
