The incorporated wave gives the component its spring effect. With an installation height reduced by up to 50 percent compared to conventional compression springs, they are a space-saving alternative for static to medium dynamic use. Despite their reduced overall height, wave springs can generate the same force as compression springs. The required spring constant can be determined and produced by the number of turns, the waves and the wave sizes.
