A compact hydraulic rotary actuator that converts hydraulic pressure into precise 180\u00b0 rotational motion \u2014 delivering 2,800 N\u00b7m of torque at 21 MPa rated pressure. Unlike a hydraulic motor (which rotates continuously), the rotary actuator provides controlled, limited-angle rotation for positioning applications: turning valves, rotating equipment platforms, swinging material handling arms, and positioning heavy loads with arc-second precision.<\/p>\n<\/section>\n

How the Hydraulic Rotary Actuator Produces Torque<\/h2>\n
<\/div>\n

\"Hydraulic<\/p>\n

The rotary actuator uses a helical spline mechanism \u2014 hydraulic pressure acts on a piston, which moves linearly along a helical groove machined into the output shaft. As the piston moves, the helix converts the linear motion into rotation. The 688 cc displacement means 688 ml of hydraulic oil produces one full 180\u00b0 rotation.<\/p>\n

At 21 MPa rated pressure, the actuator produces 2,800 N\u00b7m of output torque \u2014 equivalent to the force needed to rotate a 1.4-tonne mass at 1 metre radius. The starting pressure of only 3.1 MPa means the actuator begins rotating under minimal system pressure \u2014 important for applications where the load varies from zero to maximum during the rotation arc.<\/p>\n

Two mounting configurations are supported: cross-over installation (maximum bending torque 16,900 N\u00b7m) and cantilever installation (7,100 N\u00b7m). Cross-over mounting is used when the actuator is supported on both sides of the rotation axis. Cantilever mounting \u2014 where the actuator is supported on one side only \u2014 is common on crane swings and material handling arms.

Rotary Actuator vs Hydraulic Motor vs Rack-and-Pinion<\/h2>\n
<\/div>\n
\n
\n

Rotary Actuator: Precise Positioning<\/strong><\/p>\n

Limited rotation (180\u00b0), high torque, precise angular control. Ideal for applications that need to rotate to a specific angle and hold \u2014 valve actuation, platform positioning, equipment indexing.<\/p>\n<\/div>\n

\n

Hydraulic Motor: Continuous Rotation<\/strong><\/p>\n

Unlimited rotation, continuous output. Used for wheel drives, winch drums, and conveyor drives. Not suitable for precise angular positioning \u2014 no inherent angular feedback or holding capability.<\/p>\n<\/div>\n

\n

Rack-and-Pinion: Alternative 90\u00b0\/180\u00b0<\/strong><\/p>\n

Uses a linear cylinder + gear rack to drive a pinion. Compact for 90\u00b0 applications but less torque-dense than a helical spline actuator at 180\u00b0. The rotary actuator integrates the conversion mechanism internally \u2014 no external gearing.<\/p>\n<\/div>\n<\/div>\n<\/section>\n

Frequently Asked Questions<\/h2>\n
<\/div>\n
\n
\n

What applications use a 180\u00b0 rotary actuator?<\/h3>\n

Common applications include: large valve actuation (ball valves, butterfly valves), crane swing mechanisms, material handling arm rotation, platform indexing, mould rotation in foundries, and gate\/barrier actuation. Any application requiring high-torque, limited-angle rotation.<\/p>\n<\/div>\n

\n

Can the rotation angle be limited to less than 180\u00b0?<\/h3>\n

Yes \u2014 mechanical stops can limit the rotation to any angle within the 180\u00b0 range. The actuator can also be controlled hydraulically to stop at any position within its range using proportional or servo valves.<\/p>\n<\/div>\n

\n

What is the difference between cross-over and cantilever installation?<\/h3>\n

Cross-over: the actuator is supported on both sides of the output shaft \u2014 like a beam supported at both ends. Maximum bending torque 16,900 N\u00b7m. Cantilever: supported on one side only \u2014 like a diving board. Maximum bending torque 7,100 N\u00b7m. Choose based on your mounting geometry.
