Description
Hydraulic rotary actuator with 180~2700 N.m output torque, max rotating angle 180°/360°, displacement 64~1830 cc, radial load 1984~14770 lb. Helical hydraulic rotary actuator can be used as a rotational hydraulic cylinder, shaft output or flange output is available. ATO recommends use the hydraulic rotary actuator with a balance valve to control the hydraulic actuation system better.

Advantages
- Compared with the linear cylinder actuator added with auxiliary mechanism, hydraulic rotary actuator is compact in structure and smaller in volume, and does not require other structural parts to assist.
- Compared with the vane rotary cylinder, the internal leakage of hydraulic rotary actuator is very small, almost 0.
- The hydraulic rotary actuator only needs a small displacement, and the minimum can reach 20cc.
- Hydraulic rotary actuator can output very high torque, up to 74630 N.m.
- Hydraulic rotary actuator can achieve 0-360° rotation
- The hydraulic rotary actuator can bear large radial load and axial load.
- Installation modes are diversified, and the mounting method can be customized for hydraulic rotary actuator according to customer needs.
- The efficiency of converting hydraulic thrust into output torque is relatively low (45%~80%). After frequent use of hydraulic rotary actuator, temperature of the hydraulic system rises quickly. Please pay attention to temperature control.

Hydraulic Rotary Actuator Output Modes Diagram
Hydraulic rotary actuator output mode is the installation mode of helical pair, standard modes are shaft output and flange output. If you need other output modes, please contact us.
Hydraulic Rotary Actuator Installation Modes Diagram
Hydraulic rotary actuator installation mode is the mounting of the main body, standard modes are foot/flange/saddle/rail types. If you need other installation modes for different working conditions, please contact us.
Tips: Hydraulic rotary actuator working principle.
Hydraulic rotary actuator is a special hydraulic cylinder, which converts the thrust of hydraulic oil through the screw pair to output torque and rotation angle. The main structure of a hydraulic rotary actuator includes body (also called housing) and a screw pair. The body is generally used for installation and fixing, and the screw pair is used to output torque and angle rotation.
