Here at Caleb Components, we offer a wide range of standard DIN 2093 Disc Springs (also known as Belleville Washers).
These are also known as Conical Washers.
Our range starts from as small as 8mm x 3.2mm x 0.2mm all the way to 100mm x 51mm x 7mm.

Disc spring when stacked together or used on a single basis has the effect of a high force (compared with a compression spring) with relatively small amount of space.
