Stress concentrates at areas where there is a change in shape in a spring.
Material: Piano wire type A, SWP-A Wire diameter: Φ3.5 In springs, stress (load) during use tends to concentrate in areas where there are changes in shape. In tension springs, stress is likely to concentrate at the base of the hook, which can lead to issues such as breakage at the hook part. The hook of this spring is shaped like a U-hook. To avoid problems caused by stress concentration, we have processed the bending radius at the hook's rise to be larger. If you are having trouble with tension springs, please feel free to consult us.
