 The unique quality of constant force spring makes it a perfect balance for heavy moving parts. If your equipment requires springs, consider constant force springs. This is a kind of tension spring. They do not obey Hooke’s law, so their force remains unchanged, even when deflected.

Constant force spring can be used in almost all kinds of products. Some of the largest consumers are medical device manufacturers. Machines, dental X-ray equipment – and almost any articulated and heavy equipment – are equipped with constant force springs. Smaller constant force springs for medical devices are also part of syringes and drug injectors. We can also find a large number of constant force springs in daily necessities, such as retractable key chain, retractable dog rope, vacuum cleaner, thread winder, safety belt, window balance system, indoor shutter and monitor lifting and so on.

Due to the flat force curve of constant force springconstant force spring is suitable for applications requiring stable motion range and constant load. To learn more about this type of spring and see if it can be used in your device or application, please contact our engineer.

      So what are the advantages of constant force spring?
      1. Small space requirements;
      2. Provide a stable range of motion;
      3. No inertia can be overcome;
      4. Install to existing hardware;

      5. Produce a balance effect.

   Because of these advantages, constant force springs have sufficient versatility and can be used in many applications that require constant load to balance, tension, retract or distribute. This is why they are often used to enhance surgical equipment, expand and retract doors on aircraft, and balance windows.
