Neturen manufactures and sells ball screw shaft materials with high surface hardness produced by tempering, surface hardening, and surface tempering through high-frequency induction heating, and with outstanding roundness and straightness by centerless grinding.
After various types of processing by our customers, they become ball screw products, which are widely used in industrial machinery, precision machinery, and the like.


For materials other than the above (S55C, SUJ2, etc.), please contact us.
Please consult us separately for hardness and other mechanical specifications.
Even heat-treated and fine-diameter materials are provided straight.
We perform centerless grinding and provide materials with the required wire diameter accuracy.
The shaft material is particularly strong, straight, and round, which helps to reduce lead time in ways such as eliminating O.D. finishing operations for customers who perform whirling.
