Convoluted air spring

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. Below is the air spring components.

1. AIR INLET
1/4" NPT is standard. 3/4" NPT is also available for most parts.
2. BLIND NUT
3/8-16 UNC thread x 5/8" deep (two or four per each plate depending on part size). Used for mounting the part.
3. UPPER BEAD PLATE
Permanently crimped to bellows to form an airtight assembly which allows for leak testing before the unit leaves the factory. Zinc/chromate plated for rust protection.
4. GIRDLE HOOP
Wire wound type shown, molded into the bellows.

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
5. BELLOWS
6. LOWER BEAD PLATE
