Media Lubricated Solution with hybrid bearings

For centrifugal compressors that use different Freon refrigerants, hydrodynamic and roller bearings have traditionally required oil mixed in with the refrigerant. In a unique, oil-free design for large-capacity air conditioners and compressors, SKF hybrid bearings – with ceramic rolling elements of silicon nitride – allow the refrigerant to be used as lubricant.

Superior corrosion and fatigue resistance

This groundbreaking technology provides many design and operational advantages and eliminates oil-related environmental concerns. Already at work in industry leading chillers, the PRL Media Lubricated Solution from SKF can help:
  • Increase energy efficiency
  • Reduce operating temperatures
  • Increase bearing service life
  • Extend maintenance intervals
  • Reduce lifecycle costs
