Technical Information

The life of the constant force spring is predictable. A life cycle is an extension and retraction of either the whole spring or any portion of it. A low estimate of cycle life will lead to early failure. A high estimate, which makes the spring larger and more expensive than necessary. The force of the spring should be equal to the requirement of the application. The normal tolerance for a constant force spring is +/-10%.

There are various mounting methods available based on your application, including single mounting and multiple mounting. Please consult with one of our experts. Visit our constant force spring page for more details and mounting methods.
