The variation in initial tension also affects the load.
The material used is "Piano Wire Type A, SWP-A," with a wire diameter of Φ0.4. The hooks at both ends are shaped as "round hooks," which are less likely to cause issues such as breakage or deformation. The hooks are slightly smaller compared to the body, but they can be formed to be smaller or larger. There is a gap in the body, which is to ensure that the initial tension (*) is zero. *Please refer to the related link for information on initial tension. Due to the manufacturing process, some variation in initial tension is unavoidable, and a tolerance of ±15% is established under JIS standards. The variation in initial tension can affect the load, but by leaving a gap in the body, this influence can be eliminated. Our company handles the manufacturing, design, and prototyping of tension springs. Please feel free to consult us if you have any concerns. Tsuruoka Spring Co., Ltd.
