The multiple layers are wound by a continuous steel wire, so the Crest to Crest Wave Spring is also a stable spring structure. The characteristic of the Crest to Crest Wave Springs is that with the increase of the number of layers, the stiffness of the wave spring will decrease proportionally with the number of layers, but without changing the force value, this will have a closer force value in a larger compression space, that also is, various applications that require elasticity, even if there are large manufacturing tolerances, the Crest to Crest Wave Springs will provide similar force values within this wide tolerance range.
