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.
