Extension Springs are mechanical springs that feature tightly wound helical wire coils that elastically deform as they absorb tension loads. As the name suggests, these tension loads cause the spring to extend in length.

What is a Stock Extension Spring? A stock extension spring is a premade in-stock off the shelf mechanical spiral spring device designed to store and release energy through a pulling force. Unlike compression springs, which resist compressive force as they are compressed, extension springs are made to resist force when pulled apart.

Helically wound to oppose resistant forces, extension springs have consistent mechanical energy to return to its no-load, compressed position. The ends of the spring are attached to components intended to move apart, with the extension spring providing a reliable return force.

Jan 6, 2023 · An extension spring, also known as a tension spring, is a helical length of tightly coiled metal, usually fitted with steel hooks or loops at either end for easy attachment to various fixtures, equipment and components.

Extension springs, also known as tension springs, apply a resistive force as the spring extends and are commonly utilised to move or return a component part. Extension springs require special ends to permit application of the load and these ends assume many forms.

An extension spring is a type of helical (coiled) spring designed to store energy and resist a pulling force. When extended, it exerts a return force to pull the components back together. These springs are used in various applications requiring tension, resistance, and the ability to return to a pre-determined position after being stretched.

While both torsion springs and extension springs serve the purpose of storing and releasing energy, their fundamental differences lie in their load application and resulting motion. Torsion springs work by twisting, while extension springs operate by stretching.
