Classification and selection of high temperature preloaded disc springs
Measure and load the load of the combined disc spring on a testing machine with an accuracy of not less than 1%. (I≤10 pieces, butt combination) Use lubricant in the test, and the hardness of the pressure plates at both ends needs to be above 52HRC.

What aspects should be paid attention to when installing the disc spring?
The disc spring is a conical annular disc spring that bears an axial load. Generally, the thickness of the disc is constant, and the load is evenly distributed on the inner edge of the upper surface and the outer edge of the lower surface. Disc springs are usually made of spring steel and can withstand static, shock or dynamic alternating loads and meet stringent requirements for fatigue life and load loss.
