Lee Spring is promoting its REDUX Wave spring series of ex-stock flat wire compression springs that optimise performance in space-limited environments. Lee Spring REDUX Wave springs can replace conventional round wire compression springs in applications across many industries, from aerospace, machinery and automation, to electrical, fluid control, hand tools, valves and seals. For applications where stock sizes are unsuitable, Lee Spring can manufacture custom REDUX Wave springs to order.
Wave springs can reduce the size and weight of the assembly by as much as 50 per cent. Items such as connectors, mounting dampers and pumps can be made much smaller than would otherwise be possible. Generally wave springs occupy 30–50 per cent 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, are lighter and cost less to manufacture.
REDUX Wave springs are designed to be used over a rod/mandrel or in a hole/tube for support, thereby preventing distortion and ensuring longevity in service. They are manufactured with either plain ends (wavy) or squared-flat ends (shim ends) from a single filament of type 17-7 PH stainless steel flat wire formed in continuous precise coils with uniform diameters and waves. This grade of stainless steel gives an excellent combination of strength and corrosion resistance. Careful selection of alternative materials 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, or where uniform force distribution is needed and/or uniform rotational pressure is required over 360 degrees. They are suitable for both static and slightly dynamic load applications.
Lee Spring's REDUX Wave spring series includes designs to fit 1/4 and 5/16inch hole diameters, as well as designs in the 1/2, 9/16 and 5/8inch ranges. They are offered in free lengths from 0.060inch (1.52mm) to 2inch (50.80mm) to meet load requirements from 1.3lbs (6N) to 90lbs (400N). Custom sizes can be designed and manufactured to order.
Lee Spring is ISO 9001:2015 certified, and both Reach and RoHS compliant. Engineering and technical assistance is available for customers selecting stock springs or specifying custom springs.
