Overview
NACHI-FUJIKOSHI was founded in Toyama in 1928 by Kohki Imura, on the view that Japan needed to make its own machine tools. The company built a steel mill of its own ten years later, and its bearing business grew out of that: its own material, its own heat treatment, its own cutting.
That is unusual. Most bearing makers buy their steel. Petrofab holds NACHI in Doha and quotes the rest of the NACHI catalogue through its supplier base.
What we supply
Ball, cylindrical roller, spherical roller, taper roller and needle roller bearings, alongside hydraulic equipment, cutting tools and robots, in metric and imperial sizes.

Reading a NACHI number
These are the codes on the NACHI bearings we hold.
| Code | What it means |
| W33 | A lubrication groove around the outer ring with three holes through it, so the bearing can be greased in place through the housing |
| E, EX | Optimised internal design, for a higher load rating than the base number |
| C3 | Internal clearance greater than normal |
A bearing usually has an equivalent under another brand, and the letters are where the two differ. Send whichever number is in front of you and we will identify what fits.
Ordering
Send us the NACHI number with the quantity. If the marking has worn off, send the bore, the outside diameter and the width, and tell us what it runs in and how hard it works. We will identify the equivalent and quote it. Quantities and delivery are confirmed on the quotation.
