Extension springs absorb and store energy as well as create a resistance to a pulling force. Extension Springs are attached at both ends to other components. When these components move apart, the extension spring will pull components together again.

These springs are coiled wire in the shape of a helix that is twisted about the axis of the coil.  As sideways forces are applied to the ends of the spring, the coil twists tighter.  Whenever there is a need for rotational torque forces, torsion springs can be used to store and release energy.

Tension springs are made from different qualities of wire and are tightly coiled. The spring stretches when bearing force. The ends are formed into hooks for easy assembly into the target product. The springs are usually made in round, cylindrical sections while the hooks can be round, half-round, U- or V-shaped or square.
