Is best to not get in the habit of mixing terms. the piston is the component within the cylinder that the air acts upon, the device itself, however is called a "pneumatic cylinder" ("pneumatic linear actuator" is also acceptable). (the or retract part was superfluous, I just wanted to clarify that it does work both ways sometimes)
