Wave Spring Washer

The Wave Spring Washer is made as per DIN 137 and DIN 6904. It is made from prime quality spring steel, stainless steel, and copper. It is readily available in every standard size. It is designed to offer a compensating spring force and maintain a load or take up shock. It is a disc of irregular shape formed in such a way that when loaded it deflects, acts like a spring, and provides a preload between two surfaces. It is very useful for limited radial space and moderate thrust load, e.g., axial loading of ball bearings. The number of waves can be two, three, or more. The spring rate is proportional to the number of waves raised to the fourth power. It is generally preferred as cushion/cushion spacers between parts on shafts or to take up the probable deviation in assembled parts. It is positioned underneath a nut, an axle bearing, or a joint, to reduce friction, avoid leakage, isolate, stop loosening or distribute pressure.
