|Wave washers, also referred to as wave springs, are wavy metal washers designed to provide a compensating spring force or absorb shock when under load. Many design variations have evolved to best serve these basic functions.
Wave washers are one of several types of spring washers. They are defined by their wave-like appearance and their ability to bear a load as they are deflected in a linear range.
Wave spring washers are typically used in thrust loading applications for small deflections, particularly where radial space is limited.
Wave washers can help offset tolerance deviations in the assembly process and reduce loosening due to vibration.
