Pneumatic actuators fall into two classes: linear and rotary. Linear actuators move objects in straight lines, at the same time as rotary actuators turn objects, or rotate them in varying directions. Air cylinders (also known as pneumatic cylinders), the commonest type of linear actuators, use pressurized air to pull and push piston rods out and in of cylinder barrels. This motion moves mechanisms connected to the rods, or (for detached items) directs or blocks shuttle the use of rod-attached plates. Air cylinders execute pushing, pulling, lifting, lowering, pressing, and stopping functions, and they come in several different body types, including round, compact, tie-rod, guided, slide, and clamp. Pneumatic cylinders may also be either single acting, with one compressed air port to push the rod in a single direction and a spring to go back the rod, or double acting, with two compressed air ports on opposite ends of the cylinder to both extend and retract the rod. For quieter piston operation, air cylinders can come with cushioning in one or both ends of their barrels. Several mounting styles are to be had both for attaching the air cylinder ends to moving components in a pneumatic system and for mounting to rigid surfaces. Air cylinders are used in industrialized automation tasks in automotive, food processing, material handling, and robotics applications, among others.
