About This Product

■Product overview

After the primary winding process, the product is manufactured by winding in the opposite direction in the secondary winding process. It is a type of contact spring and is used in a case. When stored in the case, it has a spiral shape, but when removed from the case, it becomes S-shaped, hence the name S-shaped mainspring. Frictional losses of energy occur because adjacent coils are in contact with each other. However, unlike ordinary contact springs, the S-shaped mainspring is wound in the opposite direction, so the tension is applied uniformly to the entire spring, allowing it to wind back smoothly, reducing friction loss and increasing torque. Masu. Suitable for thin and long mainsprings where friction loss tends to be large.

■General materials

Stainless steel strip (SUS301, SUS631, SUS632J1)

■Main uses

Wristwatches, opening/closing assist for sliding doors, door closers for sliding doors, fall prevention balancers, seat belts, partition belts
