It is made with alloy material with the Characteristic of short working stroke, large load, small space occupied, high safety and long service life, the main material used are 50CrVA and 60Si2MnA with diameter maximum 280mm.


The disc spring is tapered in the axial direction and special spring loading, under load deformation, saving a certain potential, when the bolt loosening, disc spring release energy to maintain the pressure at the flange connection between the sealing requirements. Disc spring stress distribution from the inside to the outside of the uniform decline, can achieve a low stroke high compensation effect.

1. large rigidity, strong vibration absorbing ability, can bear large load with small deformation, suitable for small axial space requirements.

2. with variable stiffness, the spring has a wide range of nonlinear characteristics.

3. with the same dish spring using different combinations, can make the spring characteristics in a large range of changes. The utility model can adopt the combination mode of the combination and the combination, and can also be combined with different thickness and different number of slices.

When folded, with the same number of spring deformation, the more the bigger loads.
