Rotary Actuators
PHD offers a complete line of Rotary Actuators with a wide range of options.   Our pneumatic and hydraulic rack-and-pinion Rotary Actuators are available in miniature series as well as larger series for applications requiring up to 31,000 in-LB of torque.

Rotary Actuators (Series 018075, 018050, 0180375)
PHD Miniature Rotary Actuators are lightweight, compact units for small part orientation or part turn over. Adjustable stops provide 0° to 180° rotation for pneumatic use. Also available in 3 Position and Air/Oil Tandem versions.

Advantages: Available in two sizes, zero backlash at ends of rotation for precise positioning.
Rotary Actuators (Series 1000-8000)
Series 1000-8000 Rotary Actuators are a rugged line for pneumatic or hydraulic service. These units have a wide range of rotations, options, and shaft configurations allowing them to be configured for most rotary applications. Standard rotations range up to 450° with torques to 31,800 in-lb.

Advantages: Four bore sizes available in single and double rack models, wide range of options available.
Rotary Actuators (Series 2000-8000 Air/Oil)
Air/Oil Tandem Rotary Actuators provide the smooth control of hydraulics with the simplicity of pneumatics. One end of the actuator is a closed loop hydraulic control member. The other provides pneumatic power to the racks.

Advantages: Four sizes available in both 2 and 3 position models, standard built-in flow controls.
Rotary Actuators (Series 2000-8000 Multi-Position)
Multi-Position Rotary Actuators can yield three, four, or five rotary shaft stop positions. Each position is located by means of positive internal stops.

Advantages: Four bore sizes available, wide range of options available, output torque up to 15,900 in-lb [1797 Nm].
Rotary Actuators (Series RA)
PHD Series RA Rotary actuators have zero backlash at ends of rotation providing precise rotary positioning. Large shafts, bearings, and rack provide high load-stopping capacity, exceptional radial and axial bearing load ratings, and long unit life. Built-in optional shock absorbers provide smooth deceleration of external loads.

Advantages: Available in five sizes, six standard rotations, mounting patterns on three surfaces provide flexibility in design and unit mounting.
Rotary Actuators (Series RF)
The Series RF Rotary Actuator is available in 14, 20, and 25mm bore sizes with standard rotation of 180 degrees and torque ranging from 7 to 67 in-lb at 100 psi. All units feature built-in standard angle adjustments and are infinitely adjustable from 0-180 degrees of rotation providing superb flexibility and control. PHD’s internal urethane shock pads provide quiet operation and end of rotation deceleration with precise repeatability. The Series RF Rotary Actuator operates with zero backlash at the end of rotations for precise rotary positioning.
PHD RIxH
Rotary Actuators (Series RI)
Series RI and Series RIxH Rotary Actuators offer standard 2-day delivery.  Series RI Rotary Actuators incorporate internal air passages within the rotary pinion to allow pneumatic coupling to other devices without external tubing.  Series RIxH Rotary Actuators incorporate a hollow pinion to provide protection and routing for electrical cables and air lines.

Advantages:  Available in three sizes, six torque ranges, imperial or metric units.
PHD RI
Rotary Actuators (Series RL)
PHD Series RL Rotary Actuators cover a wide range of sizes from miniature 12 mm bore units to 63 mm bore units. These actuators have a very high torque to envelope ratio and are capable of very high rotation velocities. Built-in optional shock absorbers provide smooth deceleration of external loads.

Advantages: Available in eight sizes, six standard rotations, built-in optional shock absorbers provide smooth deceleration of external loads.
