Tension Spring Heavy Load Type

Frequently asked questions about this product

1. What does the initial tension of a tension spring mean?

The initial state of a tension spring (when no tension is applied) is generally a tight state. As the tension applied increases, the tension spring begins to be stretched from the tight state. When the length of the tension spring begins to increase, the tension applied at this time is the initial tension of the tension spring. Due to the process of the tension spring, the initial tension and spring constant of our company's tension spring are reference values. There may be differences between batches. Our company guarantees that the maximum load of the tension spring is the standard value.

2. For a length-specified tension spring, does the benchmark maximum stretch length of this tension spring refer to the total length that can be stretched? Or does it refer to the distance that can be stretched?

For this series of springs, the benchmark maximum stretch length must be calculated as the maximum stretch length, and the maximum stretch length refers to the distance that can be stretched.

3. How to match the specifications of the tension spring and the spring support?

(1) The wire diameter of the tension spring must be smaller than the d value of the spring support, otherwise it will not pass through.

(2) The inner diameter of the tension spring must be larger than the D or W value of the spring support, otherwise there will be interference during installation.
