Mainspring / List of 4 manufacturers
What is a Mainspring?
A mainspring is a spring made from a thin strip of metal wound into a spiral shape, primarily used for storing and releasing energy. It is commonly found in watches, toys, winding mechanisms, measuring devices, and camera shutters, providing sustained manual or mechanical motion. The mainspring efficiently stores energy by being wound and releases it as it unwinds. Its compact design and durability make it suitable for precision machinery. Typically, mainsprings are made from spring steel, which offers both resilience and elasticity.
Application of Mainspring
✅ Mechanical watches
Storing energy when wound to power the watch’s movement.
✅ Toys
Wind-up mechanisms that make cars or animals move.
✅ Retractable tape measures
