The spring is a functional component that causes 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. At Sho-wa Springs, we have been offering the "San-Es Series" for 44 years since its launch, and we now provide a rich lineup of 920 types of compression springs, 424 types of tension springs, 104 types of free-size tension springs, and 270 types of torsion springs. We can also respond to immediate delivery requests for large springs starting from one piece and small springs starting from a bag of 20 pieces! *Please note that the spring post has been discontinued. 【Special specifications not listed in the catalog can also be prototyped from just one piece!】 Feel free to contact us. ■ Catalog-listed standard springs - Compression springs - Tension springs - Torsion springs - Free-size tension springs ■ Others - Flex shafts - One-touch couplers - Non-standard wire torsion springs - CWS (Coiled Wave Springs) ◎ You can view the digest version of the comprehensive catalog by clicking the "PDF Download" button below.

Distributors
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.
