Extension Springs

Extension springs are available in a variety of materials, the most common being carbon steel or stainless steel, depending on the environment into which the spring is entering. End coils can be single or double German loop, single or double English loop, side loop, extended hook loop or even no loops according to application. More technical ends are available i.e. swivel hook, reduced/enlarged diameter loop or screw end on request. Wire size from 0.25 mm (0.010″) up to 19 mm (0.750″). We have facilities for both hand-made and automated spring manufacture.

Here at Davies Springs we do not just talk about springs but we actually have the machinery and expertise to manufacture and therefore we can create a wide variety of solutions.

Q . Are Extension Springs and Torsion Springs the same?

A. No, but they are similar. On a door for example an extension spring will expand and contract when operating.

A torsion spring in such an application will last longer because they are sturdier and turn during operation

Which Do I Need Torsion or Extension Spring

The simplest answer is get in touch with us and explain what is the function of the spring. How Many cycles do you expect it to last? Typically torsion springs will last longer than extension springs.

From your information we will be able to offer you some options., we supply a huge range of springs will be able to come up with a first class solution.
