Airpot stock self-aligning pneumatic actuators provide designers self-aligning rod capability along with extreme low friction and precise control of movement and force. This product group makes possible accurate force actuation and uniform motion with slow, smooth movement, even over distances less than 0.01 inch, or cycle rates at very high speeds up to 10 cps or more. There are a variety of rod connection choices available for easy, low friction mounting and alignment. The Airpot self-aligning Pneumatic Actuator is the most compact of the Actuator line. It is available in 6 bore sizes ranging from .22” to 1.75”, the lowest mass of all Airpot actuators and uses low friction ball joints or pin-links at both the piston and rod ends to allow the piston to self-align and reduce side loads.
