Pneumatic cylinders are devices that use compressed air to create linear motion. They consist of a cylinder, a piston, and end caps. When air is introduced into the cylinder, it pushes the piston, causing it to move. This movement can be used in various applications, such as in manufacturing and automation systems, to perform tasks like lifting, pushing, or pulling objects. These cylinders are known for their simplicity, reliability, and speed. They come in various sizes and configurations to suit different needs. Common types include double-acting and single-acting cylinders, which differ in how they use air to move the piston in one or both directions.
