Disc springs are designed to resist high forces in very short working strokes. The advantage of these springs, which have a very short spring length, is that they produce very high power with little movement when pressed. Çakır spring makes shot-peening application to the disc springs and applies length precipitation so that the fatigue and blockage problem of the springs are eliminated. Disc springs are sometimes used singly, sometimes in stacks. Disc springs are produced from a special material, chrome vanadium steel 50CrV4(DIN 2093). In addition, production is made from stainless steels X9CrNi18-8 (AISI 301), X4CrNiMo17-12-2 (AISI 316). Yayse Yay also manufactures from special materials for needs.
