What is a Pneumatic Cylinder?

A pneumatic cylinder converts compressed air into linear mechanical motion. It is one of the most widely used actuators in industrial automation.

How Does a Pneumatic Cylinder Work?

Compressed air enters the cylinder and creates force on the piston, generating linear motion.

Force formula:

F = P × A

Types of Pneumatic Cylinders

Single Acting Cylinder

• Air operates in one direction

• Spring return

Double Acting Cylinder

• Air operates both directions

• Higher force

Compact Cylinder

• Small space applications

ISO 15552 Cylinder

• Standard dimensions

Applications

• Automation machines

• Packaging machines

• Conveyors

• Robotics

• Automotive production

Selection Criteria

• Operating pressure

• Stroke length

• Required force

• Mounting type

• Environment

Conclusion

Pneumatic cylinders provide reliable linear motion in automation systems.
