A pneumatic cylinder is a mechanical device that uses compressed air to produce linear motion. It consists of a cylindrical chamber with a piston inside, which moves back and forth when air is introduced or released. This motion can be harnessed to perform various tasks, such as lifting, pushing, or pulling objects in industrial applications. Pneumatic cylinders are commonly used in automation systems, manufacturing processes, and robotics. They are favored for their simplicity, speed, and ability to generate significant force relative to their size. Additionally, they require minimal maintenance and can operate in various environments, making them versatile tools in many industries.
