Constant force springs are aptly named for their ability to exert a uniform force throughout their working range. These springs are essentially tightly wound coils of spring steel or stainless steel, with the inner end secured over a shaft and the outer end extending outward. The material’s natural curvature across its width generates a consistent retraction force, making these springs ideal for applications requiring steady and predictable performance.

Constant force springs can also be configured in a motor arrangement, where the spring winds onto a smaller drum during operation. This setup enables the creation of constant torque motors or rewind systems, which are particularly useful in counterbalancing applications. Their versatility extends further, with common uses including fast-acting fire dampers in air conditioning systems and product-pushing mechanisms in point-of-sale displays.
