Your Source for Hydraulic Rotary Actuators designed to 

outperform the ever changing challenges of the environment they are put into


Hydraulic Rotary Actuators

Rotary actuators are compact and efficient, and produce high instantaneous torque in either direction. This makes them widely used in precision control systems and in heavy-duty machine tool, mobile, marine and aerospace applications.  

Helical actuators convert the linear rotation of a piston to rotational movement by multiple helical gears. The rotational movement is greater if the linear movement of the piston is longer. Applications for helical actuators have found use for boom positioning, head rotation, and wheel steering in agriculture harvesters, for example, and in lifting positioning, and steering applications in the construction, energy, marine, material handling, military, mining industries, and valve operations.
