A compression spring that exhibits stable deflection (shrinkage) and generates a large force with a small change in amount, standardized as CWS. It contributes to precise force retention and control, as well as miniaturization of products.
CWS stands for Coiled Wave Spring, which is a compression spring formed from flat wire. It has stability that prevents tilting when compressed and exerts a large force with a small amount of deformation, making it suitable for various applications such as miniaturization of products, quality improvement, precise force retention and control, and suppression of design errors and play. Now, as a standard product that can be delivered quickly and inexpensively from a single piece, "CWS" has been newly introduced by San-Ei Spring. 【Features of CWS】 ◎ Capable of producing large loads with small deformation The height of the "spring" can be shortened, allowing for miniaturization of products and space-saving in the "spring" section. ◎ Stable deflection (compression) Due to its structure that uniformly bears the load across the entire spring, it is strong yet does not tilt when compressed. ◎ Reduce Almost no scrap is generated in the production of CWS. *For more details, please download the PDF materials or feel free to contact us. ★ A printed version is also available.

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.
