Bellows Air Spring Styles.

Bellows air springs have one, two or three convolutions in a flexible member. There are two styles of bellows designs:

1. Crimped design bellows air springs feature an end retainer that is permanently attached to the air spring by crimping a retainer around the built-in bead wire of the flexible member, or bellow.

2. Sleeve style bellows offer similar characteristic to crimped design bellows, but the flexible member is constructed without internally molded bead wires, much like that of a rolling lobe bellow. The end retainers are permanently attached by pinching the flexible member between the end retainers and external crimp rings, which are then swaged to the proper diameter.

Of all of the different types of air springs, sleeve-type bellows air springs require the least amount of force to compress.
