The advantage of the product:
This air spring is for damping. Its a rubber and fabric bladder
that houlds air pressure to support a load and isolate passsagers
and cargo from the shovk of motion caused by road irregularities.
As the air prressure increases, the air spring can support more
load while the spring rate increased. The larger the air spring,
the greater the maximum load it can support. Compared to
traditional springs, it is more competitive. And its advantages are
as follow:
1.The low cost,wide range of specifications.
2.The long service life, no maintenance and lubriction, without the
need for internal control rod or piston.
3.No friction effect, soft medium.
