Electro-hydraulic actuator all-in-one

A Complete Actuation System that is Factory Engineered and Ready to Install

Fusing the Power of Hydraulics with the Precision of Servo Control


The S-series SMART Electro-Hydraulic Actuator (SHA) combines proven technologies into an innovative new actuation product with servo actuation control. We also have a long stroke actuator with up to 120".The SHA offers significant advantages compared with hydraulic cylinder actuators or high-force Electro-Mechanical ball screw / roller screw actuators including:

  • Eliminates costly, messy and energy-wasting hydraulic power units used with hydraulic cylinders and the all-in-one design of the SHA eliminates hoses and leaky connections.
  • Provides high force-density at a very cost-effective alternative to Electro-Mechanical actuators and requires far less maintenance.
  • Has built-in precision servo control of position, force and speed; costly and difficult to do with hydraulic cylinders.
  • Ideal in rugged applications that damage and cause pre-mature failure with ball screw/roller screw actuators.
  • Simple setup and integration with common networks, including CanBus, Ethernet, Modbus and others.
  • Comes as a complete package, factory-tuned and ready to install saving hours of time.


Overview Specifications:

  • Force Range: Up to 85,000 lbf (377 kN)
  • Speed: Up to 45 in/s (1,159 mm/s)
  • Speed Up to 34.5 in/s (877 mm/s)
  • Voltage 230, 460 VAC
  • Configurations: Parallel, In-Line, 90 degree
