The secret that spring manufacturers won’t tell you – Why the springs you purchase are prone to breakage

We often encounter people asking why springs break during use. Below we have summarized 8 reasons for your reference.

broken springs

1、The arbor is too small or the spring is placed horizontally, and the spring and the arbor are worn and broken.

2、When the mandrel is too small, the assembly surface is not flat, and the parallelism of the two ends of the positioning surface is poor, it will cause the spring to be compressed and twisted and locally generate high pressure and fracture.

3、The core shaft is too short and the end is not chamfered, which will cause the spring to break due to friction and wear of the core shaft.

4, the use of foreign matter between the spring ring and the ring, so that the actual effective number of turns reduces the high stress caused by the fracture.

5、The spring is used in series so that it is bent and exceeds the length of the mandrel or countersunk hole, or the spring itself breaks due to the small difference in the load of the weaker one with a larger compression amount.

6、The use of more than the maximum compression amount and the resulting high-efficiency stress causes the spring to break.

7, the spring material is not uniform, or impurity content exceeds the standard resulting in stress concentration fracture.

8, the spring over-burned, rust, too hard, and an excessive extension will reduce its tensile strength and fracture.
