The Tension Springs

Tension springs are also known as extension springs. Drawbar springs are also an example of extension spring.

To get an idea of tension spring in action, you can compare it with a trampoline. When an outside force creates tension in the spring then it uses that energy to pull the components (the spring is attached to) back together.

Tension springs are tightly wound coils and are designed to operate with the force known as ‘tension’. 
Tension springs or you can call them the extension springs are helical wound coils with a hook, loop, or end coil designed at its one or both the ends. Hence, the extension spring or tension springs can be of many types depending upon their end design.

This spring can be attached from both the ends to the other components and the tension is created in the spring which in turn attempts to bring the components back together if they try to move further apart.

The coils of the spring touch and are tightly bound until a force is applied then spring coils are pulled apart as the components are moved in the outward direction.


The process of spring making involves hot and cold coiling procedures.

Different types of tension spring designs

The distance between the end design and spring body can be adjusted to get the desired spring design and depending upon this variety of spring designs can be created.


Tension spring hook types
One more spring design customization that’s attainable is done by providing variations in hook types of the tension springs to fit the customer’s need.
The variations in spring designs based on spring hook types are -

  • Long round end hook over the center. 
  • Hand loop and hook at right angles. 
  • Machine loop and machine hook.
Tension springs can be made from different materials – stainless steel, music steel (spring steel), hard drawn, beryllium copper, oil tempered, and phosphor bronze. At Khodiyar Spring Industries we make stainless steel tension springs.

What are the common uses of tension springs?

The primary function of tension spring is to absorb and store energy and resist the pulling force or the tension applied to them. When the load is applied the tension spring gets stretched and tries to get back in its shape by pulling the components or loads attached to the ends of the spring.

Tension springs are often deemed fit for lever-based mechanisms. They absorb energy and create resistance towards the pulling force.

Applications of tension springs

There are many uses of tension springs that solely rely on their unique properties of absorbing, storing energy, and pulling back to regain its normal shape. These are versatile springs and their usage spans across different industries.


Extension springs/tension springs are mostly used in –
  • Washing devices.
  • Toys.
  • Trampolines.
  • Garage door assemblies.
  • Carburetors.
  • Vise-grip pliers.
  • Small medical devices.
  • Machine’s brake springs.
  • Farm machinery.
  • Levers.
  • Robotics.
  • Construction components.
Benefits of using tension springs

The benefit of using tension spring is that they differ from other springs in the tightness of their coils. If you compare tension springs with compression springs the latter one is usually has more loosely held coil. This tightly wound coil design of tension springs is thus an essential feature that enables the spring to stretch more.

Before the tension springs are ready to be sold they undergo a series of tests so these springs are reliable and the spring seller lists the properties of the spring. Features like -seat pressure and coil bind height are mentioned.
