A wave spring is a compression spring made of coiled flat wire with waves added along the coils to give it a spring effect. Redux Wave springs can be used in place of conventional round wire compression springs in applications requiring tight load deflection specification in space critical environments. Generally, they occupy 30-50% of the compressed height space of comparable round wire springs offering more deflection with the same load specifications. This not only provides for space savings, but also smaller assemblies that use less materials, hence lower production costs.

Redux Wave Springs are manufactured from a single filament of flat wire formed in continuous precise coils with uniform diameters and waves. They are manufactured with either Plain ends (wavy) or Squared-flat ends (shim ends). Generally, 17-7pH is used as the standard material for wave springs. Careful material selection is required for operating environments such as high temperatures and corrosive media.


Wave springs are found in a wide variety of applications where structural considerations restrict the installation height, where uniform force distribution is needed and/or uniform rotational pressure is required over 360°. They are suitable for both static and slightly dynamic load applications. However, fatigue is critical while designing a wave spring for dynamic load applications. For higher life cycles a stronger spring is needed. Special solutions must be found for extremely dynamic applications, since considerable stress on the sine wave curves can cause material abrasion at the contact point. Typical applications include connectors, clutches, valves, pumps, seals, medical equipment etc.
