Series AH hydraulic actuators are double acting actuators with hydrostatic bearings, best for dynamic material and component testing. The actuators have hydrostatic bearings for no friction and no hysteresis operation up to their nominal load.


  • Additional plastic coating ensures no damaging of the bearings if the nominal side load is exceeded
  • The system pressure for the Series AH actuators is 280 bar
  • The actuator will reach its nominal load at 250 bar
  • The actuators have an integrated displacement transducer for measuring the piston rod position


  • internal drain for operation without leakage pump
  • enlarged end cushions
  • strengthened piston rod
  • piston rod rotation lock
  • non-standard stroke and load on request
