NACHI Bearings
NACHI is a Japanese precision engineering manufacturer founded in 1928 as part of the Fujikoshi Corporation. NACHI produces bearings alongside machine tools, hydraulic equipment, cutting tools and industrial robots — an integrated manufacturing capability that directly underpins the quality and consistency of their bearing products. Boundary dimensions follow ISO 15, ISO 355 and AS 2729 across the catalogue.

NACHI Bearing Range at AIMS Industrial
AIMS Industrial stocks 166 NACHI bearings across a comprehensive range of types and series. Deep groove ball bearings form the largest part of the range, covering the 6000, 6200 and 6300 series in open, metal-shielded and rubber-sealed (2NSE) configurations, with and without C3 internal clearance, including snap ring groove variants. Angular contact ball bearings (40° contact angle, single row) are available for combined load applications.
NACHI cylindrical roller bearings in the NJ configuration provide high radial load capacity for gearbox and motor applications. Tapered roller bearings cover metric and inch series. Spherical roller bearings are stocked in the 22300 series in both straight-bore (EXQW33) and tapered-bore configurations. Spherical thrust roller bearings (29300, 29400 series) handle heavy axial loads in vertical shaft applications.
Why NACHI
NACHI bearings are manufactured to tight dimensional tolerances with consistent surface finish quality across production batches. As an integrated manufacturer, NACHI controls the steel, heat treatment and machining processes in-house — giving traceability and consistency that matters in critical replacement and OEM applications. Mining, manufacturing and agricultural maintenance teams across Australia specify NACHI where bearing failure carries significant downtime cost.
Bearing Selection & Maintenance
If you're replacing an existing bearing and need to confirm the equivalent, our bearing cross-reference guide covers the standard codes used across NACHI and other major brands. For installation, alignment and failure diagnosis, see the bearing maintenance guide. Type-specific guides: deep groove ball bearings and thrust bearings. When removing a stuck bearing, the bearing puller guide walks through the options.
