Air Spring Bellow Type FS W01-358-8014 1003588014C Air Bag Auto Parts

Convoluted air springs have various areas of utilization like lift-axle air springs or industrial applications. Convoluted air springs are generally used for lifting axles and preserve the tires when the vehicle is empty.

Aside from that, they are also utilized in industrial applications as pneumatic lift cylinders or suspension elements to absorb vibrations. These air springs are easy to mount and they last long.

The convoluted air springs also known as bellow type air springs are made from heavy duty, metal wire reinforced rubber and come with one or two “bellows” as shown in the image.

Like the sleeve style air springs, crimp rings are used to secure bag to endcaps.

The larger diameter of the convoluted air springs gives it high load handling and extra lifting capability. These type of air springs are most suited for medium to heavy duty trucks, work trucks, motorhomes and trailers.

In certain vehicles where there is not enough room to accommodate a double convoluted air spring, Pacbrake kits are made using the single convoluted air spring option. The single convoluted air bags however do not have the same amount of travel as the double convoluted ones.

The double convoluted air bags are most widely used in the industry due to their shape and design that allows to lift more weight with less air pressure compared to sleeve style air bags. For instance, where a sleeve style air bag needs 50 psi to lift a load of 700 lbs, the double convoluted air spring can do the same job with an air pressure of 25 psi.

At Pacbrake, we take the guesswork out of the air bag selection process providing you with the best possible configuration for your truck. Our engineers choose the right bag that provides you with the most comfortable ride quality, handling and control over your load.
