DIN 2093 Series C
The "C" typically refers to the middle thickness-to-diameter ratio among the standard dimension series available
Also known as disc springs are conical washers designed to be loaded in an axial direction.
Because of their unique convex shape, they provide a much higher spring force in a highly compact, short-stroke space compared to traditional helical or coil springs.
By arranging the washers in stacks, you can customize the characteristics of the system to your exact needs:
Stacking Increases total deflection while keeping the same force as a single disc.
Parallel Stacking Increases the total spring force while keeping the deflection of a single disc.
