Types of Air Cylinder
Air cylinders come in various sizes and appearances, with three primary types available in the market:
Single acting cylinder: This type harnesses compressed air pressure to generate force in one direction, typically outward. It employs a spring to return the force to its original position. To accommodate the space required by the spring, the cylinder often features an extension.
Double acting cylinder: These cylinders utilise air pressure to execute two distinct strokes – extending and retracting. They are equipped with two ports, one for the instroke and another for the outstroke.
Rodless band cylinder: This type offers precise load control by omitting the piston rod. It employs a magnet or mechanical coupling to transmit force within the cylinder. The cylinder incorporates two flexible metal bands: one serves to prevent air from escaping, while the other safeguards the slot and inner band.
Design of Air Cylinders
The Air Cylinder's design depends on its intended use, with various options to choose from. These cylinders can be constructed from materials like aluminum, steel, nickel-plated brass, or stainless steel, selected based on factors such as temperature, humidity, and the level of stress the cylinder will undergo.
There are different types of Air cylinders:
Tie rod cylinder: This is the most commonly used type and is considered to be the safest.
Flanged-type cylinder: Fixed flanges are attached to the cylinder, a feature more commonly found in hydraulic cylinders rather than pneumatic ones.
Threaded end cylinder: The ends of this cylinder type are screwed onto the body.
