The sensor controls the free height and suppresses load variation.
The material used is "spring stainless steel wire - SUS304WPB." To minimize load variation, coiling is performed while controlling the free height with a sensor. Only the large diameter side's seat winding is tightly wound, while the effective winding section is tapered in pitch, and both ends are not ground. Due to a large spring index (*) and a fluffy shape that is prone to deformation, care is taken during heat treatment to prevent entanglement between springs. *Spring index: The value obtained by dividing the average coil diameter by the wire diameter. It serves as a guideline for the difficulty of spring manufacturing, with JIS standards recommending a range of 4 to 22. If you have any issues with springs, please feel free to consult us. Our technical staff will respond carefully. Technical contact: Ujiie Phone: 0235-22-0407 FAX: 0235-22-0546 Email: web@tohj.com Tsuruga Spring Co., Ltd. for springs We also support web meetings.
