Hydrostatic flat bearing - Moving high load at “quasi Zero” friction

  • Almost "no friction" between pad and machined surface
  • Leak free. No leaks out of the HydroPad.
  • Integrated in the load applying cylinder
  • Measure and control system

Features and benefits:

  • Speed up to 2 m/sec
  • Can withstand up to 2000 ton of load
  • "Quasi null" zero friction sliding surface
  • Self aligning spherical bearing


  • Anti Seismic Device Testing
  • Testing of wind mill thrust bearing
  • Accurate / stick slip free movement of heavy equipment

Our overall supply package consists of :
