Pneumatic Air Cylinder

Pneumatic cylinders are mechanical devices which use the power of compressed gas to produce a force in a reciprocating linear motion. Like hydraulic cylinders, something forces a piston to move in the desired direction.In manufacturing industries, pneumatic cylinders will often be used for opening valves, doors,taking things on or off conveyor belts and lifting heavy objects. In the automotive industry, pneumatic cylinders have a different role. They're used in cars and trucks to be used for suspension and brakes.
