Tension Springs
What are Tension Springs?
Tension springs, otherwise known as extension springs, are engineered with an initial tension which allows them to store energy, exerting a ‘pull’ force when stretched. The energy stored within the spring creates resistance, making the spring return to its original shape. Extension springs have attached points at each end to receive their pulling force, which is often in the form of hook ends or loops.
Common Applications of Tension Springs
Tension springs are frequently used in lever-based and open-and-close applications. Tension springs provide a counterbalancing force that is integral to opening and closing and keeping hatches in place. For instance, they exist in garage doors, pliers, and loft hatches. This means they have several applications within the automotive industry in the form of doors, hand levers, and foot pedals. They are also found in trampolines, providing the core tension that gives the trampoline its signature jumping capability.
Tension Spring Materials
Tension springs are customizable to meet your exact requirements, including in the material they are made from. The spring material must take into account its application, which may include considerations such as temperature, exposure to moisture, and load weights. For instance, if your spring will be exposed to moisture or chemicals, then we recommend choosing a corrosion-resistant material like stainless steel. Our standard tension springs are crafted using unalloyed spring steel, which caters to applications up to 104°F, so if the spring will be exposed to higher temperatures, then consider using stainless steel, which can operate up to 302°F.
Types of Extension Springs
We offer a diverse range of tension springs and end fittings, each designed to suit a different purpose. In addition to our tension springs with loops, we stock tension springs with turnable loops and tension springs with turnable bolts, which enables seamless rotation of the loops or bolts to meet any desired position. We also supply female thread fittings for extension springs, which allow for a higher load on the spring and easy mounting without the need for special tools.
