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.

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.

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.

Designing and calculating torsion springs can be troublesome and complicated, which may be a concern for you. In response to such requests, we have newly standardized torsion springs. We offer three types with materials made of stainless steel wire, wire diameters ranging from 0.3 to 2.0 mm, inner diameters from 3 to 14 mm, and winding angles of 90°, 135°, and 180°. We maintain a total of 270 types in stock at all times and are ready to deliver immediately. We supply springs with stable performance in small quantities. ◎ How to select springs (1) Determine the inner diameter (2) Decide on the torsion angle (φd) (3) Check if the allowable torsion angle φd and allowable torque T meet the usage conditions. (4) Determine the installation space for the spring.

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.

We are currently offering a free "Flexible Shaft Guidebook." Please feel free to request it using the form below. Our flexible shafts, which transmit rotational force in various shapes, come in a standard product lineup called the "Flex Shaft Standard Series." Choose the appropriate flexible shaft based on the required length, rotational force (torque), and necessary bend (R). Using the "Easy Search" feature on our website makes selection easy. You can also leave the selection process entirely to us, and we would be more than happy to assist you. The standard series can be easily purchased online, so we hope you will take the opportunity to experience its convenience. ◎ Feel free to consult us about anything! We are confident in our prototypes and custom products! - We will select and propose specifications tailored to your needs. - We are happy to accept orders starting from just one unit. - We have a proven track record of over 2,000 types of custom products in the past. Basically, there are no shapes we cannot create. Please feel free to consult us about anything.
