The Composition Of Industrial Convoluted Air Spring Element Has The Following Aspects
❶Nut / Blind Nut – As well a permanent part of the Cover Plate assembly. Provides an alternative to bolt installation system. It is inside defect within the iron plate
❷ Gas Hole / Air inlet / Air Fitting – Most usually 1/4 N.P.T. which provides the air entrance to the rubber bellows.
❸ Cover Plate - Curled up to more durable bellows design and the largest quality control in the factory. Allows 100% of the leak test before shipment.
❹Rubber Bellows - Air Bellows includes four layers of materials: an inner layer, two layer cord - reinforced fabrics, and a cover. Construction of a natural rubber provides – 65F functional properties.
❺ Bumper block / Buffer block - Solid rubber or engineering plastic device designed to prevent major damage to the vehicle or suspension in the event of a sudden loss of air pressure in the spring.
❻ Girdle Hoop / Girdle Ring - Molded wire-wound ring to provide lateral stability of the complex type spring bellows.
GUOMAT Air Springs can last at least twice lifetime, always as much as four times longer than steel springs!
