Though there are many pneumatic cylinders available, these machines generally fit into one of three categories: single-acting, double-acting, or multi-stage, telescoping cylinders. Single-acting cylinders, also referred to as SAC' s, use air pressure to drive a rod in one direction (usually out) and then a spring pulls the rod back into the starting position. Because the compressed air takes up a lot of room, SAC' s often have limited extension. In addition to limited extension, the spring in single-acting cylinders also robs the overall force created by the air pressure. Thus creating disadvantaged to SAC' s over other types of cylinders. Double-acting cylinders (DAC' s) use air pressure to both extend and retract the strokes of the rods. Unlike single-acting cylinders, DAC' s are not limited in length. But with longer lengths, comes the vulnerability of piston rods buckling and/or bending. Lastly, telescoping, or telescopic, cylinders can be either single or double-acting. The cylinders in these machines are made of a series of hollow pieces that increase in diameter. While this design allows for a longer stroke, there is an increased chance for the piston to become warped. Because of this weakness, telescopic cylinders are primarily used in applications with little to no side loading. Although these are the most commonly pneumatic cylinders, they certainly are not the only types of pneumatics produced. Other common types of pneumatic cylinders include, but are not limited to: rod-less air cylinders, impact air cylinders, cushion end air cylinders, tandem air cylinders, and rotary air cylinders.
