Possible Applications


  1. Industrial Field: It can be used in industrial machinery requiring shock absorption and load - bearing, such as in some automated production lines, where it helps to reduce vibration and impact during equipment operation, protecting the machinery and improving its service life. It may also be used in pneumatic actuators of industrial valves to provide flexible force transmission and precise position control.
  2. Transportation Field: In the suspension systems of some vehicles like trucks and trailers, it can improve ride comfort and stability by evenly distributing the vehicle's weight and absorbing road vibrations. It might also be used in the air - spring - based suspension systems of railway vehicles to enhance ride quality and stability.
