How are air bellows constructed

The flexible bellows are made from fabric reinforced rubber and usually have one, two or three convolutions, depending on the stroke required. The air bellow is fixed between two chrome steel end caps and chrome steel studs are welded to each end cap; this makes bellows easy to install, particularly as they have higher tolerance to mis-alignment than other linear actuators. However, the full surface of the metal endcaps must be used to bear the force and lateral guides should be used.

What are typical applications

Pneumatic air bellows are most commonly used for raising and lowering functions. They are particularly suitable for applications that require short stroke (up to 410mm) and high load capability (up to 237,600N at 7 bar). Good examples are handling applications, like scissor or platform lifts, machine stops or footings, hopper vibration dampers, reel tensioning, stamping presses and vehicle suspension.

There are more such applications where the air bellows are used either to produce motion (as an actuator) or to provide isolation in high vibration situations.
