[NM1 Adoption] Non-magnetic high hardness high precision LM guide and ball screw: THK

Through special heat treatment technology, we have achieved a balance between the necessary functions for linear and rotational guidance and non-magnetic and ultra-high corrosion resistance.

This is a product of LM guides and ball screws made from the corrosion-resistant special alloy "NM1." Even in special environments affected by strong magnetic fields and corrosive agents, it demonstrates linear and rotational guidance performance comparable to that in normal environments, making it a "high-function non-magnetic and ultra-high corrosion-resistant product." It supports cutting-edge scientific fields. ★ High Level of Non-Magnetism With a relative permeability of less than 1.005, it exhibits a high level of non-magnetism and hardly retains any magnetism. *Generally, non-magnetic steel has a relative permeability of 1.02 or lower, and non-magnetic bearings are around 1.01 or lower. ★ Excellent Load-Bearing Performance With a hardness of 58 to 64 HRC, it allows for the production of products with significantly superior load-bearing performance compared to conventional non-magnetic steel. It contributes to downsizing the entire equipment and reducing costs. ★ Achieves High Precision and Smooth Movement Unlike ceramics, it has moderate elasticity, allowing for preloading and achieving high-precision operation.
