Compact air bellows are pneumatic devices used to raise and lower heavy equipment and awkwardly shaped loads. They are similar to actuators but provide frictionless thrust because the return stroke is created by the action of a spring mechanism.
Compact air bellows are made from fabric-reinforced rubber fixed with steel end caps on both sides. They are less liable to misalignment and come with larger operating diameters than normal linear actuators.
Compact air bellows can be used in many ways:
There are three basic options for compact air bellows: single-, double- and triple-convolution designs. Which you choose will depend on the stroke range and load capability you need.
