The reasonable installation of the air spring airbag can prolong its service life, and the unreasonable operation of the geometric principle will greatly reduce its service life. In the case of long-term pressure, only a small adjustment of the operating geometry can increase the service life by 4-10 times. However, in actual situations, there may be less pressure for a long time, and the lifespan will not be so greatly extended, but the fact that the lifespan can be extended does exist.
First, avoid centerline deviation. Bladder airbags do not have a membrane airbag for centerline deviation. If you have any questions, please contact Goodyear.
Second, the pressure should be appropriate. When an air spring air bag is subjected to a small pressure, the inner material is folded and contacted, so when the air bag is subjected to a large pressure, the air spring air bag will be greatly worn, which will cause internal wear and reduce life.
