NACHI industrial bearings are among the most widely used motion transmission components, engineered to handle both radial and axial loads with high precision. They are available in deep groove, angular contact, and self-aligning types, manufactured from chrome alloy steel with surface hardness between 60 and 64 HRC. The inner diameter ranges from 10 to 200 millimeters and the outer diameter up to 320 millimeters. Manufacturing tolerances comply with ISO 492 standards, typically in P6 or P5 accuracy classes. The optimized raceway design reduces friction by up to 30 percent and extends bearing life under continuous load conditions.
The production of NACHI industrial bearings involves multi-stage heat treatment and micron-level grinding to enhance fatigue strength and thermal stability. These bearings operate reliably within a temperature range of minus 30 to plus 150 degrees Celsius. Lubrication is provided by lithium-based NLGI-2 grease or ISO VG 46 oil. The permissible rotation speed varies from 6,000 to 24,000 rpm depending on the bearing type. NACHI bearings are widely used in electric motors, gearboxes, CNC machinery, and automated industrial systems, offering high efficiency, long service life, and superior engineering reliability.
