Single 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
Bearing rings and balls
The bearings are heat stabilized up to at least 150 °C (300 °F).
Cages
Steel, brass or PEEK cages can be used at the same operating temperatures as the bearing rings and balls.
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.
Lubricants
Temperature limits for greases used in sealed LILY angular contact ball bearings are provided in table 1. For temperature limits of other LILY greases, refer to Selecting a suitable LILY grease.
