When calculating the lifespan of a tension spring, we evaluate not only the strength of the body but also that of the hook.
The tension spring in the photo was designed and prototyped by our company at the request of the customer. The design conditions were the coil outer diameter (+0) and the load from installation to maximum. Additionally, we have ensured that the specification meets the durability requirement of over 1 million cycles. When calculating the lifespan of the tension spring, we evaluate not only the body but also the strength of the hooks at both ends. We chose a "round hook" shape, which is resistant to breakage and deformation. Our company accepts design and prototyping of tension springs. If you provide us with the general specifications (design conditions), we will propose and produce the optimal specifications and prototypes. Please feel free to leave the lifespan calculations to us. If you have any concerns, please do not hesitate to consult us. Tsurugaoka Spring Co., Ltd.
