A spring is a functional component that can cause problems even if just one is missing, but surprisingly, designing one takes a considerable amount of time, and it is not uncommon for practical issues to arise. The San-Es series tension coil springs are available in a constant stock of 424 types, with wire diameters ranging from 0.32 to 2.3 mm, outer diameters from 3.2 to 24 mm, and materials including piano wire and stainless steel wire (excluding free-size tension springs). We respond to customer requests with an immediate delivery system. We supply springs with stable performance in small quantities. ◎ How to select springs (1) Determine the material based on the atmosphere and environment in which it will be used. (2) Decide on the required outer shape of the spring. (3) Based on dimensions such as installation, determine an approximate figure for the necessary free length of the spring. (4) Determine the required load when the length is displaced.

Even a single missing spring can cause issues for functional components, but surprisingly, designing one takes a considerable amount of time, and it is not uncommon for practical problems to arise. The Suness series of free-size tensile coil springs, which allow for arbitrary adjustment of spring length, are always in stock with a total of 104 types available, including wire diameters from 0.2 to 2.6 mm and outer diameters from 3 to 30 mm, made from piano wire and stainless steel wire, and we can respond with immediate delivery. We supply springs with stable performance in small quantities. ◎ How to select springs (1) Determine the material based on the atmosphere and environment in which it will be used. (2) Decide on the required outer shape of the spring. (3) Based on dimensions for installation, determine an approximate value for the necessary free length of the spring. (4) Decide how much load is needed when the length is displaced.

"Isn't Sanko Springs the manufacturer of San-Es standard springs?" That's right, but that's not all; we are actually also skilled in "custom springs." The proportion of custom spring production in our annual output reaches 91.1% (as of 2021). It might be fair to say that we are more proficient in custom springs. Especially in the case of torsion springs made from irregular wire materials, we boast industry-leading technical expertise and production capacity. We are happy to listen to your concerns! Sanko Springs does not easily say "we can't." Please leave your "custom springs" to Sanko Springs Manufacturing!
