With a rich lineup, our technology, backed by experience and proven results, is highly regarded worldwide!
The series consists of five types: "Power Spring," "High Deflection Power Spring," "Power Spring α (Alpha)," "LR/MR Round Wire Coil Spring," and "J Spring." In particular, "Power Spring" and "High Deflection Power Spring" are color-coded through anionic electrodeposition coating, making it easy to distinguish between various types of springs. Additionally, "Power Spring," "High Deflection Power Spring," "Power Spring α (Alpha)," and "LR/MR Round Wire Coil Spring" are made from silicone chrome steel for springs (with "LR/MR" partially made from B-type piano wire), while "J Spring" is made from stainless steel wire 304-WPB for springs, offering excellent performance in high stress, amplitude, and heat resistance. The specification table includes detailed information on spring constants, deflection, load, free length, outer diameter, inner diameter, and more. ● For further details, please download the catalog or contact us.

Company information
The powerful springs that were first standardized in Japan using non-circular cross-section materials have become the standard in Japan. Based on customer requests, we have standardized high deflection powerful springs and powerful spring α. The resin guide has been developed and standardized to maintain the original lifespan of the springs. Additionally, they are adopted in manufacturing machines and presses used worldwide, based on the international standard ISO 10243, such as ISO STANDARD. We offer sizes that match manufacturing machines used in various industries around the world, ensuring high strength and durability.
