Compression coil spring (compression spring) AP, AS San-Etsu standard spring
San-Ei Standard Series
We always have 919 types of compression springs in stock, ready for immediate delivery! Our extensive lineup is built on years of manufacturing technology and expertise in "spring design"!
The spring is a functional component that causes problems even if just one is missing, but designing one surprisingly takes a lot of time, and it is not uncommon for this to cause practical issues. The San-Etsu series compression coil springs are always in stock with a total of 919 types, featuring wire diameters from φ0.4 to 10mm, outer diameters from φ4.5 to 80mm, and materials including piano wire and stainless steel wire. We respond to customer requests with an immediate delivery system, supplying springs with stable performance in small quantities. ◎ How to select a spring (1) Determine the material based on the atmosphere and environment in which it will be used. (2) Decide on the necessary outer diameter or inner diameter of the spring. (3) Determine the free length of the spring (the length before displacement). (4) Decide on the required load (or spring constant*1, deflection amount*2, etc. may also be acceptable). *1 Spring constant: The load obtained when the spring is displaced by 1mm (load ÷ deflection amount). *2 Deflection amount: The change that occurs when a load is applied to the spring.

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.
