The single-layer wave spring is divided into a Gap Type Wave Spring and a Overlap Type wave spring. The wave spring is suitable for a variety of applications, and can accurately and reliably play a role in small deformation and low-to-medium force applications, especially suitable for work applications with small height and working space.

As the working height of the traditional stamped wave spring decreases, the outer diameter will also expand accordingly. If the outer diameter expands to the installation hole of the wave spring, the traditional wave spring will be stuck in the installation hole. The Gap Type Wave Spring and Overlap Type wave spring solve this problem very well, because when the wave spring is compressed, the gaps at both ends of the wave spring can also move freely, which offsets the radial expansion of the wave spring.
