About air spring

The main function of the rubber air spring is to eliminate and reduce the transmission of mechanical vibration, and finally achieve the purpose of noise reduction, shock absorption and impact reduction.

The rubber air spring is a curved capsule made of rubber as the main raw material, and uses air as the medium for balancing, buffering, and transmitting pressure. In the actual application process, the performance requirements of different parts of the rubber air spring are different. Generally, the outer rubber layer of the air spring needs to be resistant to aging, flexing, and has good adhesion to the cord, and has a high tensile stress; the inner rubber layer needs to be resistant to aging, has low air permeability, and has good adhesion to the cord; the cord requires a rubber compound It has the characteristics of flex resistance, heat resistance and high adhesion of cloth layer.

Operational Cautions

Air Spring failure can be caused by a variety of situations, including internal or external rubbing, excessive heat and overextension.

Temperature/Pressure Range

The ambient operating temperature range for standard air springs may vary. See the technical parameters or consult relevant personnel
The maximum pressure is 100 PSI.
