Spring fatigue is one of the most important risks in repeated-use products. Fatigue testing helps confirm whether the design can survive real operation before mass production begins.
Common applications
- Retractable products with repeated operation
- Automotive and safety-related mechanisms
- Medical and electronic devices
- Industrial products requiring long service life
Key design inputs
- Target cycle life and test speed
- Working stroke, force, or torque range
- Installation method during testing
- Failure criteria and inspection frequency
Selection notes
A meaningful fatigue test should be close to real working conditions. Testing only the spring outside the mechanism may miss friction, alignment, or assembly issues.

FAQ
Why is fatigue testing important?
It helps identify early failure risk and confirms whether the spring design is suitable for repeated use.
Should the spring be tested alone or in the product?
Both can be useful, but final validation should include the real product structure when possible.
What affects fatigue life?
Material, stress level, surface condition, working angle, corrosion, and installation alignment all affect fatigue life.
