Tension
Tension Springs
Tension springs, also known as extension springs, apply a resistive force as the spring extends and are commonly utilised to move or return a component part. Tension springs normally have special ends to allow application of the load (e.g. chest expanders) and these ends can be manufactured in a variety of shapes and sizes.
The design of tension springs is virtually the same as for compression springs, the formulae for load and stress being identical.
Tension springs, however, are different in two ways. Firstly, they are normally close-coiled whereas in compression springs the coils are open. Secondly, initial tension can be put into tension springs so that a particular load has to be applied to the spring before the coils begin to open.
Tension springs are available in a variety of different forms and are commonly used in many household products such as garage door assemblies, trampolines and white goods.
Torsion
Torsion springs differ from both compression and extension springs in both applications of load and method of operation. They are coil springs that exert a torque (or resist a torque) in an arc with the legs rotating around the axis and the body coils being stressed in bending. An infinite number of variations are possible for leg formation but simplicity is often the best guide.
Wire Form
Almost the only limit when it comes to wire form manufacture is the imagination of the designer. Almost any conceivable 2D or 3D shape can be achieved although our early involvement in the design process can help to avoid the inclusion of potential failure points. Wire forms can be manufactured using materials from drawn carbon steel and stainless steel to exotic materials such as Inconel X750, 625, 718, Nimonic 90 and Titanium.
Compression
Pressings
Pressings are springs that are manufactured from sheets or strips. They may be flat, have bends, radii, have holes or cut out shapes or a combination of all of the above and can be made from a wide range of materials and are often made from pre-hardened material although sometimes it is necessary to manufacture from annealed material and apply a post-forming harden and temper operation. Most pressings are loaded in bending with the cantilever spring being the most simple.
About Tension Springs
Tension springs are a vital and versatile component in numerous industrial and consumer applications. As expert spring manufacturers at The Active Spring Company, we recognise the critical role that tension springs play in maintaining tension and stability.
Tension springs, also known as extension springs, are designed to resist axial forces, commonly referred to as stretching or pulling forces. These springs are widely used in applications ranging from garage doors to trampolines and even in various machinery components.
Tension springs find prominent use in the construction industry, where they support overhead doors and gates, ensuring efficient and secure access control. Moreover, they are integral to the manufacturing of consumer goods, such as reclining chairs and exercise equipment, providing the necessary resistance for functional movements.
Tension springs come in various sizes and configurations to meet the specific needs of diverse applications. At The Active Spring Company, we possess the expertise to custom design and manufacture tension springs that precisely match the requirements of our customers. Parameters like wire diameter, coil direction, end hook types, and extension force are considered during the design process, ensuring optimal performance in the intended applications.

Tension Springs FAQ’s
What is a tension spring, and how does it function?
A tension spring, also known as an extension spring, is designed to resist stretching or tensile forces. It works by storing potential energy when extended and exerts an opposing force when pulled, striving to return to its original shape when the tensile force is released.
Where are tension springs commonly used?
Tension springs are versatile and can be found in applications such as garage doors, trampolines, screen doors, and various industrial machinery components where they are responsible for providing tension, extending and retracting components, or supporting weight.
What are the advantages of using tension springs in various applications?
Tension springs are known for their ability to maintain consistent tension and offer a controlled extension and retraction, making them valuable in applications requiring support, security, or balanced movement.
How do I determine the right tension spring for a specific application?
Choosing the correct tension spring involves considerations of wire diameter, coil type, spring rate, and material. The spring’s specifications should align with the application’s tensile load requirements and space limitations.
What materials are typically used for manufacturing tension springs?
Common materials for tension springs include high-carbon steel, stainless steel, and various alloys, chosen based on factors like corrosion resistance and load-bearing capacity.
What safety precautions should be taken when working with tension springs?
Safety is paramount, especially during installation or replacement of tension springs. Following proper guidelines and safety measures is crucial to prevent accidents and spring failures.
Can tension springs be repaired if damaged, or should they be replaced?
Tension springs are often replaced when damaged, as repairing them can be challenging and may not restore their original performance. Consult with professionals for replacement and maintenance.
How long can I expect a tension spring to last in typical usage?
The lifespan of a tension spring depends on factors like material quality, the frequency of extension, and proper maintenance. Regular inspections and timely replacement are key to ensuring the spring’s longevity.
Can tension springs be customised to suit unique requirements?
Yes, tension springs can be custom-designed to meet specific size, shape, and material requirements for a wide range of applications. Experienced spring manufacturers can assist in creating bespoke springs.
