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.  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)
  • Stroke Length Up to 120” (3,048 mm)
  • Voltage: 120, 240, 460 VAC
  • Configurations: Parallel, In-Line, 90 degree
