Constant force spring is a specialized type of spring designed to provide a consistent force throughout their entire range of motion. It is widely used in applications requiring continuous force or load balancing. Typically made from high-quality spring steel or stainless steel, this type of spring is precision-wound into a tightly coiled structure to ensure high reliability and stability. The key feature of constant force spring is that its force remains nearly unchanged during extension or retraction, making it ideal for smooth operation and precise control. It is commonly used in roller shutters, medical devices, automation systems, tensioning mechanisms, tool balancers and cable management systems.
We offer both standard and custom-designed constant force springs, with material options ranging from carbon steel to high-grade stainless steel and other alloys to meet varying requirements for corrosion resistance, strength and longevity. Additionally, we provide various surface treatment options to enhance durability and aesthetics.
Whether for lightweight precision applications or heavy-duty industrial use, our constant force springs deliver accurate performance and long-lasting reliability, making them an ideal choice for a wide range of industries.
