Kuhnke pneumatic rotary actuators, miniature by design, deliver a powerful and fast response to a vast number of applications that require air-powered rotary movement; specifically designed for quick and easy installation within a small envelope of space.
Pneumatic miniature rotary actuators provide a fixed 90° clockwise or anti-clockwise rotational movement; connect the respective ports via a pneumatic valve to achieve the rotational movement required. It is possible to limit the angular travel by using external stops.
Two body sizes are available, 35mm² or 50mm² as single or double acting operation with G1/8 or M5 threaded ports. The body and end caps of the rotary actuator constructed of a light aluminium alloy, the body of CrNi steel, and the rotating shaft of stainless steel ensuring durability and robustness.
Four pre-drilled holes on the face of the rotary actuator and a centre shoulder are used to mount the rotary actuator to a flat surface. Adjusting the spring tension of the single acting device is possible, should a reduced or increased return force be required.
Impulse Automation offers other rotary actuators; these are shown in the main pneumatic cylinder section where larger sizes from Ø 25mm up to Ø 100mm and rotary movements from 10° up to 720° can be found.
