Air cylinders, also called pneumatic cylinders, are mechanical devices that use compressed air to create motion. They are widely used in automation systems for tasks like pushing, pulling, lifting, and clamping. The two main types are single-acting and double-acting cylinders. A single-acting cylinder uses air pressure to move in one direction and a spring or external force to return it. It’s simple and efficient for applications that need force in only one direction, such as clamping or ejecting parts. A double-acting cylinder, on the other hand, uses air pressure in both directions, providing more control and continuous movement — perfect for precise industrial automation.
Beyond these, there are several specialized types of air cylinders designed for specific requirements. Telescoping cylinders offer a long stroke from a compact body, ideal for space-limited areas. Rodless cylinders transfer motion without an external rod, using a magnetic or mechanical coupling. Rotary cylinders convert linear motion into rotation, used in conveyors and indexing tables. Other common designs include compact cylinders for small spaces, guided cylinders for stability and precision, and tandem cylinders that combine two units for higher force. Each type of air cylinder serves a unique purpose in automation, ensuring flexibility, reliability, and smooth operation in industrial systems.
