The coil part is coiled in an elliptical shape rather than a circular one.
We received a request from a customer for "compression springs that fit perfectly in a vertically long space." The result, which meets the requirements for free length, installation, and maximum load, is this oval spring. This is a spring coiled in an oval shape (not exactly oval, but elongated oval) rather than a round coil. The material used is round wire "spring stainless steel wire, SUS304-WPB." We have processing experience with similar shapes using "piano wire (SWP-A, SWP-B)" and "beryllium copper wire (C5191W)." If you have any issues with springs, please feel free to consult us. Our technical staff will respond carefully. Turuoka Springs Co., Ltd. Technical Contact: Ujiie Phone: 0235-22-0407 FAX: 0235-22-0546 Email: web@tohj.com We also support web conferencing.
