The Structure of AIRSUSTECH Air Springs

An air spring is a carefully designed rubber/fabric bellows which contains a column of compressed air. The rubber bellows itself does not provide force or support load. This is done by the column of air. AIRSUSTECH air springs are highly engineered elastomeric bellows with specially designed metal end closures. Our standard two ply air spring bellows is actually made up of four layers:

a. An inner liner of calendered rubber.
b. One ply of fabric reinforced rubber.
c. A second ply of fabric-reinforced rubber (with the cords at
a specific bias angle to the first ply).
d. An outer cover of calendered rubber.

Many of our air springs are also available in high strength construction for higher pressures. In this case, there are four plies of fabric-reinforced rubber, with an inner liner and outer cover.
