Convoluted Air Springs:

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. 


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.



Air spring is a rubber bellow containing pressurized compressed air with an emergency rubber spring providing various suspensions characteristic to maintain a constant buffer height irrespective of the loaded condition.

The necessity for Introducing Air Spring in Hybrid Coaches:

Due to the Super-Dense Crush Load, the bolster springs become solid, which in-turn damages/breaks the coil spring resulting in discomfort to the passenger. So to overcome the above problem on air suspension (air spring) is introduced in the secondary suspension to maintain a constant buffer height irrespective of the loaded condition by varying the pressure of air inside the air spring.

Working Principle:

With changing loads, air spring reacts initially by changing the distance between air spring support and coach body. then actuating height monitoring valve( leveling valve ), either by taking the compressed air to the air spring or releasing air pressure from it to the atmosphere this process continues until the required height is maintained this mechanism ensures a constant floor height on coaches provided with air springs, irrespective of the load.
