A pneumatic piston is a mechanical device that uses compressed air to create motion. It consists of a cylindrical chamber and a piston that moves back and forth within this chamber. When air is introduced, it pushes the piston, converting the energy from the compressed air into linear motion. This motion can be used to perform various tasks, such as lifting, pushing, or pulling objects. Pneumatic pistons are commonly found in industrial applications, such as in automated machinery and robotics. They are valued for their speed and efficiency, making them ideal for tasks that require quick and repetitive movements. Additionally, they are often used in air brakes and pneumatic tools.
