Traditional coil springs are widely used throughout a variety of applications across nearly every industry. The typical end configuration for coil springs is where you have a helix, and the last turn is bent down, touching the second-to-last turn and ground to form a shim.

Wave springs offer space savings in an axial direction, in which 50 percent of the operating height can be reduced. Wave springs produce loads in shorter spaces by distributing the loads over the waves themselves by bending, as opposed to torsion. When specifying wave springs, there are many features that can be modified to suit individual application requirements. Whether you need a custom configuration or if a standard one works, modifications and customisations are often simple when it comes to coiling, as no special tooling is needed.

With multi-turn wave springs, customers often think they need a shim-ended part based on conventional coil spring designs. However, Rotor Clip engineers can help assess the right end type for wave springs, based on your application requirements. Here are the following end-type configurations offered for both single-turn and multi-turn wave springs...
