GUOMAT Air Spring Introduction 

GUOMAT air springs are engineered elastic bellows with specially designed metal end caps. Our standard two-layer air spring bellows actually consist of four layers. Many of our air springs are also available in high-strength construction to accommodate higher pressures. In this case, there are either four layers of fabric-reinforced rubber or two layers of special high-strength cord with an inner liner and outer cover.
