The N-Tubrack, a hollow rack bar from Netsuren, is an item designed for miniaturization and weight reduction that can significantly contribute to improving automotive fuel efficiency.
Through Neturen's unique cold sequential forming technology, we can shape the rack teeth from pipes, enabling a weight reduction of up to 50% compared to solid materials. Additionally, by performing full circumferential quenching, we process products that maintain precision while achieving high strength. The rack teeth can be formed into a V.G.R. (Variable Gear Ratio) shape, allowing us to meet the needs for quick stroke end and increased manual assist force at the stroke end. Since 2016, we have started mass production of hybrid rack bar blanks that combine hollow rack bars with solid materials through friction welding to support double pinion EPS.

Company information
Netsuren successfully commercialized and industrialized IH (Induction Heating) technology for the first time in Japan in 1946 (Showa 21). This IH technology is a double eco (Ecological and Economical) technology that uses clean electricity as its heat source, making it environmentally friendly and pollution-free. As a pioneer in this field, Netsuren has developed highly original products in addition to contract heat treatment processing, based on the know-how accumulated since its founding and its high level of technical and development capabilities, bringing transformation and contribution to various industries. The fact that Netsuren exists today and can contribute to society, even in a small way, is thanks to your unwavering support and warm patronage. To enhance corporate value through harmony and coexistence with customers, business partners, shareholders, society, and employees, Netsuren aims to remain a company with a dignified presence in the future.
