Air cylinders resemble any other cylinder in steam engine or cylinder in hydraulic circuit. Air cylinders are called actuators or motors. Air Cylinder is a device, which converts pneumatic power in to respired Mechanical power by reducing the pressure of the compressed air to atmospheric pressure.
The advantage of air cylinder is that it cannot be over loaded. It simply stalls when the cylinder is over loaded.The essential parts are of Air Cylinder
1. Cylinder tube2. Piston3. Piston rod4. Air inlet5. Air outlet
