What is a wave spring

Wave springWave spring, for short, is an elastic element with several peaks and valleys on a thin metal ring. It is usually used in situations where the load and deformation are not large and the spring stiffness is small and axial preload is required. Wave springs are particularly suitable for applications where weight reduction is required and where small installation space is a constraint.

Wave springs are divided into two categories: WS

series wave springs and WSS

series wave springs.

The WS series is a continuously wound corrugated spring with staggered peaks. The characteristic of this series of springs is that it can provide ideal elasticity in a smaller installation space, saving 50% of the space than ordinary coil springs.

WSS series is a staggered wave crest type corrugated spring with flat rings. In addition to having the advantages of

WS type wave spring

, this series also has flat rings at both ends of the spring

, which is quite Due to the addition of two washers, the elastic force of the spring during use is more uniform

, which is especially suitable for environments where there are holes on both end faces of the installation space

. The crest of the WS type is easy to fall into the hole and cannot be used.
