What Are Tension Springs?

Tension springs, alternatively known as extension springs or coil tension springs, are tightly wound coils engineered to function under tension force. Typically featuring loops or hooks at each end for attachment, these springs are designed to store and release energy when subjected to external forces.nnThese springs find widespread applications in various settings, from counterbalancing garage doors to farm machinery and trampolines. Their primary role is to harness external force, utilising the stored energy within the coil to draw components together, thus reverting to their original configuration. Due to their function, tension springs are tightly wound and closely coiled at rest.

How Do Tension Springs Operate?

Tension springs serve to connect two components, bringing them together when thereâ€™s a tendency for separation. When subjected to a load or force, the spring elongates to a specific length, absorbing energy and generating resistance against the pulling force. In their relaxed state, the coils of the spring are in contact with each other.nnUpon separation of the components, typically from opposing directions, the spring strives to maintain cohesion, exhibiting spring action until the force is counteracted, allowing it to return to its original state.nnMany high-tension springs are wound with initial tension, which is the force holding the spring coils compacted together. The measurement of initial tension represents the load required to overcome the internal force and initiate coil separation.

What Are the Industrial Applications of Tension Springs?

Tension springs find utility across a broad spectrum of industries, including:nnRailnAgriculturenOil and gasnAerospacenAnd numerous others.nAs tension springs suppliers, we manufacture these springs in a variety of sizes to accommodate diverse applications. Here are some common uses:nnTrampolinesnAutomotive components (interior and exterior)nGarage door mechanismsnAgricultural equipmentnPliersnMedical devices like stretchers and surgical lights

Tension Springs & Tension Spring Manufacturers

Tension springs, also referred to as extension springs, are one of the archetypal tightly wound or close coiled springs, and are, quite naturally, designed to operate with tension. When no load is placed upon the spring, the individual coils touch, yet the coils are pulled apart as the spring stretches due to the application of a force (usually from either side of the coil).

The spring will always try to revert to its original shape though, and it is this process that causes the springing action. Frequently found within lever based mechanisms or the counterbalances within garage doors, few spring types are more widespread than these.

Premium Grade Tension Springs Made by European Springs Ireland

At European Springs and Pressings Ltd, our 18 tension coiling machines are able to manufacture tension springs in dimensions of between 0.1mm and 26mm, and can create either close wound or loose wound helices with equal aptitude. We utilise both hot and cold coiling procedures, and manufacture our springs from a wide range of materials, of which steel or stainless steel are merely the most common.

There is also a diverse array of end types available for all of these springs – such as hooks, coiled loops or screw-in variants – and entirely customised end designs can also be made for you should you require them. Our techniques are highly advanced, enabling us to meet even bulk demands with impressive rapidity.

European Springs and Pressings Ltd will ensure that your tension springs are made to access their maximum possible potential; whether that means cold coiling to imbue a spring with added flexibility or developing an especially durable end fitting, your satisfaction is our priority. If you require a fine to medium weight spring then the four categories of tension spring within our established catalogue will usually house exactly what you’re looking for. However, if you need something especially specific then our friendly and professional team will be able to assist in the design of a bespoke spring to conform to your preferences, and at the most competitive of prices.
