NACHI Precision Bearings — Ball, Roller & Angular Contact

NACHI is a Japanese precision engineering company with a heritage in high-performance bearings trusted across mining, manufacturing, agriculture and industrial maintenance in Australia. Founded in 1928, NACHI produces bearings to exacting tolerances and material specifications, making them a preferred choice for OEM replacements and high-cycle-duty applications where bearing failure means production downtime. AIMS Industrial stocks the NACHI bearing range across deep groove ball, cylindrical roller, tapered roller, angular contact and thrust configurations — covering the most common industrial shaft and housing applications.

NACHI Deep Groove Ball Bearings — Open, Shielded & Sealed

NACHI deep groove ball bearings are the workhorse of the industrial bearing world — suitable for high-speed radial and axial loads across a wide range of applications from electric motors and pumps to conveyors, fans and gearboxes. Available in open, ZZ shielded and 2RS rubber-sealed configurations, with and without snap rings, and in standard and C3 internal clearance grades to suit applications with thermal cycling or interference fits. The 6000, 6200 and 6300 series cover the most common shaft sizes from 10mm upward.

• Nachi Deep-Groove Ball Bearings — Open: Open construction deep groove ball bearings for clean, dry environments where regular relubrication is practical; available in standard and C3 clearance grades across the 6000–6300 series
• NACHI Deep-Groove Ball Bearings — Shielded (ZZ): Metal-shielded bearings offering protection against coarse contamination while retaining factory grease; suited to general industrial machinery and electric motors
• Deep Groove Ball Bearing — Rubber Seal (2RS / 2NSE): Fully sealed rubber contact seals for high contamination environments; retains grease effectively and provides better sealing than shielded variants for food, agricultural and washdown applications
• Deep Groove Ball Bearings with Snap Ring & Groove (C3): Snap ring groove variant for housing designs that require axial location without an end cap; C3 clearance for applications with elevated temperatures or press fits

NACHI Cylindrical, Tapered, Angular Contact & Thrust Bearings

For applications demanding higher radial load capacity, combined loading or precision spindle performance, NACHI's extended bearing range delivers. Cylindrical roller bearings in NU, NJ and N configurations handle heavy radial loads in gearboxes and reducers. Tapered roller bearings suit wheel hubs, axles and differential assemblies under combined radial and axial loading. Angular contact ball bearings are the choice for machine tool spindles and high-speed precision applications, while thrust ball bearings manage pure axial loading in vertical shaft arrangements.

• Cylindrical Roller Bearings — NU Configuration: Inner ring flanged both sides, outer ring unflanged; allows axial displacement of shaft relative to housing — ideal for gearboxes, reducers and electric motors with thermal expansion requirements
• Cylindrical Roller Bearings — NJ Configuration: Locates shaft axially in one direction; commonly used in pairs with NU bearings to provide full axial location in both directions in heavy industrial gearboxes
• Tapered Roller Bearings — Metric Series: Designed for combined radial and axial loads; metric series covering standard industrial shaft sizes for wheel bearings, axle assemblies, crane wheels and heavy rotating equipment
• NACHI Angular Contact Ball Bearings — 7200 Series: 40° contact angle angular contact bearings for high-speed applications with combined loading; precision manufactured for machine tool spindles, pumps and centrifugal compressors
