The permissible operating temperature for indexing roller units can be limited by:
- the dimensional stability of the roller unit rings and rollers
- the O-rings
- the lubricant
Where temperatures outside the permissible range are expected, contact the SKF application engineering service.
Roller unit rings and rollers
SKF indexing roller units are heat stabilized up to 150 °C (300 °F).
The permissible operating temperature for FKM O-rings is –30 to +200 °C (–20 to + 390 °F). Temperatures up to 230 °C (445 °F) can be tolerated for brief periods.
