We always have a stock of 104 types of free-size tension springs that can be adjusted to any length, ready for immediate delivery! A comprehensive lineup created with years of accumulated know-how and technology!
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.

Company information
Our company has been dedicated to the production of springs as a specialized manufacturer for nearly half a century. In the spring industry, we are known by the standard spring brand "San-Es," and we are considered the "pioneers of standard springs" for being the first to popularize standard springs in the market. In addition to the "San-Es standard springs," we also cater to custom orders for all types of wire springs, including compression springs, extension springs, and torsion springs, as well as lesser-known but highly excellent products such as "special-shaped wire springs," "CWS," and "flexible shafts." We practice our corporate philosophy of "always being sincere and contributing to society through the creation of trusted products," and these products have been continuously loved by many customers over the years. Moving forward, in order to gain further trust from everyone, our company will work together to develop and grow daily, ensuring accurate quality and responding sincerely to customer requests as we engage in "monozukuri" (the art of making things) every day.
