Twisted coil springs STA, STB, STC - San-Etsu standard springs
We have a constant stock of 270 types of torsion springs (torsion springs and kick springs) available for immediate delivery! A comprehensive lineup created with years of accumulated know-how and technology!
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.

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.
