Every spring has an endurance limit. Meaning there comes a point where it can’t take any more stress or weight, meaning the spring won't work past a certain point of stress. The endurance limit is very similar to the elastic limit.
It’s important to know and understand the endurance limit on your springs. If not it can cause problems once the springs are in place. It really can damage the product or the spring. This is another reason why it’s best to consult with a professional spring consultant here at Coiling Technologies.
