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.
Application:
1. Mold Separator Inflatable Cushion
