Tension Springs

We manufacture a wide range of round wire tension springs to
individual requirements and keep a large selection of materials in stock.
Supply us with a drawing or enter the appropriate details on our contact
form and we will be happy to provide you with a quotation.

How they work

Tension springs are used to attach two components and bring them together when they try to detach. A high-tension spring works by absorbing energy and storing it. When tension is applied to the spring, its energy creates a resistance to counter the pulling force. The initial tension applied dictates how close these coils are. By controlling this initial tension, it is possible to customise the spring to cater to specific load requirements. The coiled spring design of a spring is what provides the strength and elasticity. A tension spring is tightly wound and when in a rest state, it remains coiled very closely. We include interfaces such as eyes, hooks or loops at both ends to facilitate attachment to other components.

Tension spring common uses

The design, size and flexibility of a tension spring determine its best uses. Garage door assemblies are common uses
of tension springs. The automotive industry utilises tension springs in some exterior and interior components. Other
applications include trampolines, farm machinery, vice-grip pliers, toys and washing devices among others. Tension
spring manufacturers allow a variety of dimensional ranges. When looking at tension springs for sale, factors such as
the material, wire size, finish and ends will determine the appropriate choices.
