REDUX™ Wave Springs from Lee Spring – an enabling technology

Product News Thursday, July 18, 2019: Lee Spring Ltd

Lee Spring REDUX™ wave springs offer a way of performing a spring function in minimal spaces – even perhaps where no other spring could work effectively. Typically, REDUX wave springs occupy just 30-50% of the compressed height space of the conventional round wire springs, yet they offer more deflection with the same load specifications. This not only helps to save space in the applications but also reduces the production costs, as fewer materials are required and often enable devices that would not otherwise be feasible.

Wave spring applications typically include connectors, pumps, clutches, seals, medical equipment and valves. All these applications require springs that offer uniform force distribution and/or uniform rotational pressure over 360° in restricted spaces.

A wave spring’s design is similar to a compression spring, but the wire used is coiled and flat. Waves are added along the coils to give a spring effect. They are often used instead of round wire compression springs in space-critical environments that require tight load deflection.

Typically wave springs come in a wave top to wave top format manufactured from a single filament of Type 17-7 Stainless Steel flat wire formed in continuous precise coils with uniform diameters and waves. REDUX wave springs are offered in diameters from .236" (6.00mm) to 1.772" (45.00mm) to meet load requirements from 2lbs (0.9kg) to 90lbs (40.8kg).

Wave springs are suitable for static and slightly dynamic load applications. More dynamic applications require special solutions because the additional stress put on the waves is likely to cause abrasion of the materials at the point of contact, in this case customers should contact Lee Spring to discuss relevant options.

REDUX wave springs from Lee Spring are suitable for use in space critical applications where they are designed to replace conventional round wire compression springs when required. REDUX wave springs offer tight load deflection and typically occupy a very small area in relation to the high performance of the spring – this enhances efficiency and reduces operational cost, operating space and permits smaller assemblies.
