Temperature limits

The permissible operating temperature for Y-bearing units is, depending on unit variant, mainly limited by:
  • the housing material
    • The permissible operating temperature for housings made of composite is –30 to +120 °C (–20 to +250 °F). Other housing materials do not limit the permissible operating temperature of the unit.
  • the PA66 cage (→ Cages)
  • the 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.
  • the lubricant
When temperatures outside the permissible range are expected, contact the SKF application engineering service.
