Pneumatic Actuator Integrity Guide

Sep 10, 2025

Pneumatic actuators are another type of automation device with a variety of functions and applications.


This guide covers the definition of an actuator, common actuator types, and provides information on non-pneumatic and non-linear actuators.


In general, as long as you have access to shop air (or a compressed air source), pneumatic actuators are a cost-effective solution.



What is an actuator?


An actuator is a device that converts energy—such as electrical, pneumatic, or hydraulic—into mechanical motion or action.They are composed of cylindrical or rectangular chambers, pistons, and various ports for air intake and exhaust. When compressed air enters the cylinder, it pushes the piston, causing the piston rod to extend from the cylinder and generate linear motion. This simple type of automation device is widely used across many industries.
