Spiral springs, also known as flat spiral springs or clock springs, are mechanical components that store and release energy through rotational or torque forces. Their coiled, flat design allows them to provide precise control in applications requiring controlled torque or return mechanisms. Spiral springs store energy when wound and release it smoothly when unwound. Unlike helical springs, their force is generated by the rotational movement of their coils. They offer high fatigue resistance to withstand repeated winding and unwinding cycles. These springs are Resistant to creep and set over long-term use.
