What Are Air Cylinders and Rotary Actuators?

So, what are air cylinders? In simple terms, air cylinders are mechanical devices that are able to convert air energy into linear motion; in other words, the air cylinder is the part of a compressed air system or air machine that is primarily responsible for actually using the compressed air to make movement happen.

There are lots of different kinds of air cylinder, such as compact air cylinders, which are known for being small and portable, as well as much larger and more complex models, like guided air cylinders. Each variety of air cylinder is unique, and they may also have various extra parts or accessories attached to them, like sensors that help to detect where the piston is situated or mounting accessories to help them fit onto other parts and surfaces.

A rotary actuator, meanwhile, is a type of actuator which is able to produce rotary motion or torque. Rotary actuators come in many forms, with electric actuators being the most common, but there are also air and hydraulic rotary actuators, too, which can be used in a broad range of applications and industries.

What Are Air Cylinders Used for?

The main purpose of air cylinders is to help generate motion using compressed air in a compressed air or pneumatic system. Each type of cylinder can work a little different. Since double-acting pneumatic cylinders are among the most common, we'll use them as an example.

In double-acting pneumatic cylinders, compressed air passes in via a port at the cap end, which pushes the piston forward and extends the rod of the piston. When this happens, air is pushed out via the port at the rod end. Compressed air can then enter via that same port in order to retract the piston, which draws the piston back in, and the process can then repeat, with the piston being pushed back and forth to make linear motion occur.
