What Is a Rubber Air Spring?

A rubber air spring is a flexible pneumatic component that uses compressed air to provide load support, vibration isolation, and shock absorption. It typically consists of a reinforced rubber bellows, metal end plates, and mounting components. By adjusting the internal air pressure, the spring delivers variable load capacities and working heights. Rubber air springs are widely used in industrial machinery, punch press machines, vehicle suspension systems, and vibration isolation equipment.
