Application
2B7403 air spring can replace Firestone W01-358-7403. It can be used in Vibratory Screens. It need low maintenance.
As the vibration load increases, the height of the spring decreases, the volume of the inner cavity decreases, the stiffness of the spring increases, the effective bearing area of the air column in the inner cavity increases, and the bearing capacity of the spring increases at this time.
When the vibration load decreases, the height of the spring increases, the volume of the inner cavity increases, the stiffness of the spring decreases, the effective bearing area of the air column in the inner cavity decreases, and the bearing capacity of the spring decreases at this time.
In this way, within the effective stroke of the air spring, the height, inner cavity volume, and bearing capacity of the air spring have a smooth and flexible transmission with the increase and decrease of the vibration load, and the efficient control of the amplitude and vibration load. It is also possible to adjust the stiffness and bearing capacity of the spring by increasing or decreasing the amount of inflation, and an auxiliary air chamber can also be attached to realize self-control adjustment.
