Sell Constant torque spring

Description

Constant torque spring is made of stainless steel. The external force rewinds the spring from the natural state to the output wheel for energy storage. When the external force is removed, the spring will return to its natural state, and at the same time, the output wheel produces a fixed torque to store the elasticity, so it is called a fixed torque spring. It belongs to the constant force spring in a way of use.
