Helical Hydraulic Rotary Actuator

Heavy duty rotary actuator for the rotation of construction machinery

The hydraulic rotary actuators designed for heavy-duty and challenging environments are notable for their reliability under tough conditions, along with high torque, strong load-bearing capacity, compact and versatile design, and diverse mounting options. These actuators are available in various configurations with rotation angles up to 360°, customizable according to customer needs.

The actuators come in versions with or without a counterbalance valve, which allows the actuator to maintain a fixed position during operation and provides protection against reverse loads.
