Convoluted Air Springs can be used on multi-axle vehicles
Convoluted Air Springs are made up of one or more convolutions, these air bellows are used on a very wide range of applications. In general they are used on multi-axle vehicles as an axle-lifting bellow when the vehicle is empty in order to protect the wheels. Convoluted bellows are easy to assemble and primarily long-lasting.
