DSO-HPE rotary actuator

Product information

DSO-HPE rotary actuator

Building on the successful design of the DSO standard rotary actuator, SPECKEN-DRUMAG has developed a rotary actuator series with a closed-circuit hydropneumatic system and automatic leakage oil compensation. The characteristic features of these actuators are precise adjustment of the angular speed over a wide range in both directions of rotation with fitted adjustment throttles and hydraulic progressive damping at the end stops. The pressure forces acting on the operating piston are transferred directly to the hydraulic medium, which enables precise adjustment of the rotating motion. The DSO-HPE rotary actuator series is manufactured with a piston diameter of 50, 63, 80 and 100 mm and with a rotation angle of 180°.

If the dimensions and weight of the actuators are less important, larger piston diameters and rotation angles be supplied upon request.

All auxiliary equipment and special pinion shafts are also available for the DSO-HPE. The cylinder tubes are made of steel; contactless sensing via a magnetic piston is therefore not possible with this combination of materials.
