wave spring washer provides medium load in a smaller axial space. The end of the cushion is overlapping or opening (when the wave number is more than 5).
Comparing with the common closed-end stamping wave spring, the non-closed structure can make the end move during compression, and effectively prevent the friction between the wave cushion and the hole. Elasticity is better. Common applications of this type of parts are near smaller bearings, where shaft movement or thermal expansion and contraction adjustments are required. This overlap is beneficial for such applications, where holes are made of materials that are softer than springs, and the material thickness of springs is relatively small.
