Rubber Air Spring Knowledge
When making air springs, the choice of material is particularly important. Only by choosing a material with good sealing properties and a tight fit with the spring, can a good air spring product be produced. One of the most trusted materials on the market today is rubber, and the springs made of rubber are rubber air springs.
The distinguishing feature of this type of spring is its strong elasticity. Although ordinary springs also have a certain elasticity, using the characteristics of rubber, rubber air springs can greatly compress air, making the load bearing more flexible. When using an air spring, the rubber can be bent arbitrarily according to the space in which the spring is placed until a most suitable shape is obtained. What's more, the rubber is lighter compared to heavier metal materials, so the entire rubber air spring is also lightweight. No matter where it is placed, the spring does not put too much burden on other parts. At the same time, the rubber hardly suffers from wear, so the service life of the rubber air spring is extremely long.
