IIS makes all types of wave Spring washers as per DIN 137 and DIN 6904. IIS Wave washers are made from prime quality spring steel, stainless steel, copper and other material which are readily available in very standard sizes. Wave washers are wavy metal washers designed to offer a compensating spring force and maintain a load or take up shock. These are the 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. Wave washers are very useful for limited radial space and moderate thrust load e.g Axial loading of Ball bearing.Wave Washers are generally preferred as cushion spacers between parts on shafts or to take up the probable deviation in assembled parts. These are positioned underneath a nut an axle bearing or a joint to reduce friction avoid leakage isolate stop loosening or distribute

- The diameter tolerances specified apply to spring washers
when pressed flat. The tolerance on coaxiality between D and D related to d2 shall be 1/2 IT 14
- Values to be complied with in the spring force test as described in
DIN 267 Part 26 have not as yet been specified for this size.
