Tension Spring Manufacturers
Also known as tension springs, extension springs are similar to compression springs but are loaded in tension. Hooks or loops are provided to allow a force to be applied, as extension springs are usually attached at both ends to other components. When these components move apart, the spring tries to bring them together again. Extension springs are wound to oppose extension and the tension of the wind can be manipulated to achieve the load requirements for a particular application. Tension springs are commonly used in machinery, levers, robotics, the automotive industry and they are a typical feature of a child’s back garden, due to their use in the mechanism of trampolines.
Here at Airedale Springs, we have the production facilities required to manufacture a wide range of extension springs, including both crossover and machine loops; and we can supply with both swivel hooks and special inserts as required.
Get In TouchVersatile Tension Spring Solutions
Our extension springs are perfect for a wide range of uses, such as lever mechanisms and doors; and by consistently producing high quality springs we are able to provide practical and useful solutions to any requirements that our clients may have. Furthermore, if you don’t have the final specification before coming to us, we have the expertise and capabilities to work with you to create a final design for tension springs that will fulfil the aim you want to achieve.
We also have a wide range of materials to choose from – depending on your individual requirements – with our engineers available to advise on whether you should opt for stainless steel, or another metal or alloy, when finding suitable extension or tension springs. Different materials will extend and contract in various ways, so it’s important to speak to one of our specialist engineers about your requirements.

Frequently Asked Tension Spring Questions
How Do Airedale Springs Design Tension Springs?
When we design tension springs, we take several factors into consideration, such as how much force the spring needs to be able to generate, whether it needs preload stretching, the number of coils (which can determine the strength of the tension spring), and the hook configuration. We’ll also take into account the nature and purpose of the spring during the design process when deciding on the ideal dimensions.
How Do Tension Springs Work?
Extension springs are similar to compression springs but are loaded in tension. Hooks or loops are provided to allow a force to be applied, as these springs are usually attached at both ends to other components. When these components move apart, the spring tries to bring them together again.
What Applications Are Tension Springs Used In?
Extension springs are found in many applications within numerous industries. One of their most famous uses is within the trampoline, but because they can be made to so many different sizes they can also be discovered in the automotive sector, garage doors, pliers, washing machines and even children’s toys. Even the medical industry can be found depending on certain extension springs (usually the very small varieties), so few other components have such a diverse array of applications.
How Can Tension Springs Be Customised?
Like many springs, extension springs can be customised to suit especially fine specifications. These customisations can include different types of materials and heat treatment, but one of the most common amendments to make to extension springs is to alter the type of loop or hook that is being used. As mentioned, extension springs are attached to other parts of a mechanism, and to enable their use within so many different appliances they can incorporate a range of hoops, hooks and even bolts to ensure a secure anchoring. Although these fixings may be small, they carry a great deal of importance.
At Airedale Springs, we can make your extension springs fit with any specifications that you desire, especially if you let us know about precise requirements like the dimensions of the hole and shaft, and we always maintain high standards of quality in our manufacture.
