Air cylinders are recognized as the final module in a pneumatic, compressed air control or in any power system. Air cylinders, or pneumatic cylinders, are tools, which switch compressed air power into a usual mechanical or automatic energy. This mechanical energy generates linear or rotating motion. In this way, the air cylinder works as an actuator in any pneumatic system, so it is as well identified as a pneumatic linear actuator. The air cylinder comprises of steel or could be of stainless steel piston, a piston rod, a cylinder container and including end covers. As compressed air progresses into the air cylinder, it moves forward to the piston along the length of the air cylinder. Compressed air or a coil, situated at the rod end of the cylinder, moves the piston back. Valves are the one that control the pour of compressed air to the cylinder.

Air cylinder producers usually generate two essential kinds of air cylinders: single acting and binary acting. The single acting cylinders are capable to perform an operating activity in one single direction. A single acting air cylinder further has air pressure on the one side of a piston flange, delivering force and motion, and a coil delivering the return power after force release. Single acting cylinders need just about half the amount of air used by a binary acting cylinder for any single working cycle. A binary acting pneumatic cylinder carries the powered of motion in common two directions, with pressure on both the sides. When a cylinder is pressed out in one single direction, compressed air moves it back in an additional direction. Air lines consecutively into two ends of the cylinder provide the compressed air.

Pneumatic systems generate large linear pressure group and comprise of an input, a course and the output. In this, the input acts as a compressed air from the compressor or from the hand pump. The course is a control device, which directs the air to the bar end or bottom of the container and the output is an expanding or withdrawing piston rod. Pneumatic schemes are used to move, pull, and lift and for other open/close doors in material management and processing. They could also hold, take away and place materials or pieces for the purpose of manufacturing.
