Air Cylinders

Air cylinders are used in industrialized automation tasks in automotive, food processing, material handling, and robotics applications, among others. Air cylinders (also called pneumatic cylinders), the most common type of linear actuators, use pressurized air to pull and push piston rods in and out of cylinder barrels. This motion moves mechanisms connected to the rods, or (for detached items) directs or blocks travel using 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 actuators fall into two classes: linear and rotary. Linear actuators move objects in straight lines, while rotary actuators turn objects, or rotate them in varying directions. Pneumatic cylinders can be either single acting, with one compressed air port to push the rod in a single direction and a spring to return 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 available both for attaching the air cylinder ends to moving components in a pneumatic system and for mounting to rigid surfaces.

Air cylinders or Pneumatic Cylinders are mechanical devices which use the power of compressed gas to produce a force in a reciprocating linear motion. Similar to hydraulic cylinders, air pressure were used to forces a piston to move in the desired direction. The piston is a disc or cylinder, and the piston rod transfers the force it develops to the object to be moved. Engineers prefer pneumatics because they are quieter, cleaner, and do not require large amounts of space for fluid storage. Because the operating fluid is a gas, leakage from a pneumatic cylinder will not drip out and contaminate the surroundings, making pneumatics more desirable where cleanliness is a requirement.

Air Cylinders with suction vacuum are available in a variety of sizes and can typically range from a small 2.5 mm (1⁄10 in), which might be used for picking up a small transistor or other electronic component, to 400 mm (16 in) diameter air cylinders which would impart enough force to lift a car. Some pneumatic cylinders reach 1,000 mm (39 in) in diameter, and are used in place of hydraulic cylinders for special circumstances where leaking hydraulic oil could impose an extreme hazard.
