Aditya Industries offers tension springs, also known as extension springs.
The main use of a tension spring is to absorb or store energy along with creating a resistance to the pulling force, the spring gets stretched as the lood is applied to it
Tension springs are attached at both ends to other components, when these components move apart, the spring tries to bring them together again; tension springs absorb and store energy as well as create a resistance to a pulling force
It is the initial tension that determines how tightly together an extension spring a coiled; the initial tension can be manipulated to achieve the load requirements of a particular application; these are wound to oppose extension
They are often tughtly wound in the no load position and have hooks, eyes, or other interface geometry at the ends to attach to the components they connect; they are frequently used to provide return force to components that extend in the actuated position.
