It's pneumatic cylinder. A cylinder is composed of a cylinder body, a piston, and a piston rod. To say you have a pneumatic piston is to say you have only one of the three major parts of a pneumatic cylinder. Basically, a piston is just a cylindrical chunk of metal with groves for retaining the seals and a hole (possibly threaded) through which the piston rod would be inserted.
