LHA Fatigue Rated Hydrostatic Bearing Actuators

Overview

The LHA series actuator is intended for very demanding testing applications where the actuator is subjected to:

  • High side loads
  • Frequencies above 100 Hz
  • Applications requiring very low actuator friction

The intent of the test system determines the actuator requirements and LINK engineers will help you determine the optimal solution for your application. The typical actuator often includes these accessories:

  • Pedestal mounts
  • Close coupled accumulators
  • Delta P transducers
  • Swivel or Ball Joints to allow lateral loads or motion
  • Load cells
  • Servo valves
  • Additional connection accessories.

Key Benefits

  • Low friction for accurate control
  • Concentric AC-AC LVDT which is compatible with testing industry control systems
  • Tungsten rod coating for greatly improved reliability
  • One piece, double-ended piston rod for improved control and reliability
  • Cushions to protect against end of stroke impact
  • Standard manifolds include cross-port bleed valve and pad for Delta-P transducer
  • Calibration sheets on all transducers
  • Maximum operating pressure 4000 PSI, 280 bar
  • Sharp edge orifice design offers improved control over capillary concept
