Our Smalley Linear Springs offer a selection of spring loads that react along a straight line as opposed to a conventional helical spring that fits in a circular cavity. This results in progressive springs which, although located in an axial direction, provides a radial force between mating components.

Linear Springs are a continuous wave formed wire length produced from spring tempered materials which act as a load bearing device. Since they are manufactured using the same technology that is applied to the production of our Smalley® Edge Coiled Flat Wire Wave Springs, they have the same load/deflection characteristics and, burr-free edge profile.

At TFC we're devoted to giving our clients the best possible products for their money and to suit their requirements; our Linear Springs are made with spring tempered materials to ensure quality and longevity, this means you can confidently use them as load bearing devices in almost any situation where a wave spring won™t do and be confident in their dependability and performance. Contact us Here for more information.

 

Materials: Carbon Steel and 17/7ph Stainless Steel.
