Introduction of Types of Pneumatic Actuators and Bellows

Pneumatic systems condense air or some other gas to elevate the pressure it emits. This high pressure gas is then applied to make machine components move. In the late 19th century, only wealthy industrialists adopted pneumatic systems, since only they had the large-scale steam engines required to operate the compression systems of the time. However, in the early stage of the 20th century, smaller and more efficient motors guaranteed the broad industrial usage of pneumatic systems. Even though they have become less welcome since the latter half of the 20th century, they are still a primary character of many businesses.

Air cylinders, or pneumatic actuators and bellows are applied in industrial devices and vehicles. They use high-powered springs to force the mechanism by approach of kinetic energy. Using compressed gas that builds up, the spring inside the pneumatic actuators or bellow is released, which brings a forceful push forward. There are many kinds of pneumatic actuators and bellows designed for various uses.

Rotary Pneumatic Actuators

Rotary pneumatic actuators offer kinetic energy in all orientations so it can be applied to revolve the blades in a rotary powered device.

Single Acting Pneumatic Actuators

Single acting pneumatic actuators create force in a single direction, making it very powerful. The spring shifts back and forth in two places.

Double Acting Pneumatic Actuators

Double acting pneumatic electric actuators create force in two directions. It has double air chambers and that is why it can bring in stroke and outstroke power.

Rodless Pneumatic Actuators

Rodless pneumatic actuators use no spring to make force, but rather a coupling mechanism that transfers compressed air.

Compact Pneumatic Actuators

Compact pneumatic actuators, or short stroke pneumatic actuators, can suit in small rooms with its short spring mechanism. It creates less force than an average length spring.

Guided Pneumatic Actuators

Guide rods are applied in guided air cylinders, or a guided pneumatic actuator. They are installed beside the piston rod so there is no rotation, or pneumatic actuator with non-rotational motion.

Adjustable Stroke Pneumatic Actuators

Adjustable stroke pneumatic actuators have movable stoppages inside its chamber so you can make a decision on how far the piston can move. This admits you to acquire the accurate amount of force necessary to power the machine.

Two Chambered Forge Bellow

Two chambered forge bellows produce an invariable stream of air. Each chamber covers fully separately, in order that while one is filling, the other is releasing. These are commonly made of fabric consolidated with synthetic rubber.

Single Convolution Bellow

A single convolution bellow can adapt to small spaces since it collapses when it is depressurized. It creates a single direction of force, from one air chamber.

Double Convolution Bellow

A double convolution bellow has two air chambers affixed by a central ring. It can create a large amount of force in a single direction by pressurized air covering both bellows.

Triple Convolution Bellow

A triple convolution bellow creates a single direction of the greatest amount of force in the bellows. It has three air chambers associated with two central rings. Each chamber is covered with pressurised gas, releases and collapses.
