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.
