Product


Constant force and power springs consist of a spirally wound metal strip in a plane shape and act as mechanical energy storage (spring motor). Due to preferred orientation strips and special raw material, SCHERDEL springs can survive the endurance test under extreme conditions, such as exposure to high heat or extreme loads. SCHERDEL manufactures constant force and power springs as individual parts, but also in complete or partial assemblies.
