NACHI-Fujikoshi Corporation was founded in 1928 in Toyama, Japan, originally as a cutting tool manufacturer before expanding into bearings. NACHI produces deep groove ball bearings, tapered roller bearings, and spherical roller bearings for machine tools, automotive, robotics, and hydraulic equipment. NACHI part numbers follow ISO base designations but use brand-specific suffixes — 2NSE for sealed variants, 2NKE for shielded variants — and proprietary series codes that require cross-referencing to find equivalent SKF or NSK parts.
