Hydrostatic Bearing Upgrade

The Outotec hydrostatic bearing (HSB) upgrade is a retrofit solution for grinding mills. Existing bronze bearing pads are replaced with pads made from an advanced compound that significantly improves the maintainability, reliability, and longevity of both radial and axial pads.


  • Extends the service life of bearing pads and makes maintenance easier
  • Improves hydrostatic efficiency of bearings
  • Reduces production downtime resulting from bearing-pad failure
  • Self-lubrication can eliminate the need for emergency oil-flow accumulator system
  • Reduces operational and maintenance costs
