Special hydrostatic test bearings


  • High radial and axial stiffness
  • No vibrations by rolling elements
  • Maximum possible damping of vibrations from testing process
  • Feasibility of making precise measurements of friction torques
  • Frictionless by low speed
  • Maximum load capacity already at speed zero
  • Free of wear, no metal to metal contact
