We A To Z Spring Industries - Spring Manufacturer in Gujarat manufacturer Torsion Spring ( https://en.wikipedia.org/wiki/Torsion_spring ) unlike compression and extension springs, which exert forces that are parallel to the spring itself, torsion springs exert a torque (or rotary / clock wise or anti clock wise ) force that rotates around the center of the spring. The ends of the spring are attached to the components, which rotate as the spring attempts to push them back into place. Common Use of torsion spring is like Clothespins, Ratchets, Ramps, Door hinges, Garage doors, Tailgates, Clipboards, Foot pedals, Safety hooks, Trailer ramps, gates and lids, Medical Equipment, Ceiling Light Fittings. In short Torsion springs are the components that upon twisting, exert a force in the opposite direction. This force is directly proportional to the twisting. When twisted, these springs store mechanical energy. When released, these springs come back to their original position. http://www.bestspring.in/home
