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.
