    Hydraulic Rotary Actuator

    Hydraulic Rotary Actuator

    Hydraulic rotary actuators achieve high torque output especially in small and narrow spaces

    Operating Technology

    The concept of hydraulic rotary actuators is based on a system where the linear motion piston is converted into a rotational movement by helical gears. Each actuator is comprised of a housing and two moving parts — the central shaft and piston. Helical spline teeth on the shaft engage matching teeth on the piston’s inside diameter. A second set of helical splines on the piston’s outside diameter mesh with the gear in the housing.

    Hydraulic Rotary Actuator Series

    • Light Series
    • Heavy Series
    • Industrial Series
    • Double Series

    Light Series Hydraulic Rotary Actuator (HSR) is suitable if you need medium torque and you have light working conditions.

    • Working Pressure up to: 207 bar 
    • Max. Drive Torque: 500 Nm – 4.407 Nm
    • Mounting Type: Foot 
    • Standard Angle: 90° / 180° / 220°

    *We can also manufacture in special dimensions and angles according to your request. Please contact us.


    Heavy Series Hydraulic Rotary Actuator (ASR) is suitable if you need much more torque than HSR and you work at hard conditions

    • Working Pressure up to: 207 bar 
    • Max. Drive Torque: 1.921 Nm – 24.295 Nm
    • Mounting Type: Foot / Flange
    • Standard Angle: 180° / 360°

    *We can also manufacture in special dimensions and angles according to your request. Please contact us.


    Industrial Series Hydraulic Rotary Actuator (ESR) is suitable if you need high torque for heavy doors or pipe bending machines.

    • Working Pressure up to: 207 bar 
    • Max. Drive Torque: 200 Nm – 32.000 Nm
    • Mounting Type: Foot / Flange
