What is a pneumatic cylinder?

A pneumatic cylinder is a mechanical device that uses compressed air to produce linear motion. It is commonly used in manufacturing, automotive, and construction industries to power a variety of machinery and tools.

The basic components of a pneumatic cylinder include a cylinder body, a piston with a piston rod, seals, and an air supply. When compressed air is supplied to the pneumatic cylinder, it pushes the piston, causing the piston rod to move.

The motion of the piston rod can be used to perform various tasks, such as lifting, pushing, pulling, or rotating.

Advantage of pneumatic cylinder

Compared to other types of cylinders or power sources, pneumatic cylinders have the advantages of being cost-effective, easy to operate, and requiring minimal maintenance.

Principle of pneumatic cylinder

The working principle of a pneumatic cylinder is that compressed air enters the cylinder body, pushing the piston to produce mechanical motion or force. Its efficiency and effectiveness can be evaluated by calculating the relationship between the work and energy of the pneumatic cylinder, which is governed by the laws of thermodynamics.

A key principle of pneumatic cylinders is the relationship between pressure and motion. The force produced by the cylinder body is proportional to the air pressure supplied to it. This means that increasing the air pressure will cause the pneumatic cylinder to produce a greater force.


Pneumatic cylinders can be divided into single-acting cylinders or spring return cylinders and double-acting cylinders. Commonly used cylinders include DNC and SI series ISO 6431 standard cylinders, SC standard cylinders, and stainless steel miniature cylinders.


Pneumatic cylinders are widely used in automation and control systems to compress and release gas or liquid to achieve the conversion of force and motion. They are used in manufacturing for assembly lines, in construction for heavy machinery, and in the automotive industry for braking systems, among other applications.
