Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Yes, 100% of N18/750-1 Single Row Cylindrical Roller Bearings leaving CHG Bearing production lines are subjected to multi-frequency Anderometer sound testing. All units satisfy baseline Z1V1 levels, with dedicated quiet-running electric motor quality (EMQ) lots certified to Z2V2 and Z3V3 standards for silent machinery integration.
Engineered according to international ISO boundary plans, CHG Bearing supplies N18/750-1 with a precision bore diameter (d) of 750 mm, an outside diameter (D) of 920 mm, and a nominal ring width (B) of 78 mm. This configuration yields an effective cross-sectional wall thickness of 85.0 mm and an envelope ratio (D/d) of 1.23, delivering compact rigidity for OEM machinery housings.
To match diverse operational dynamics, CHG Bearing supplies N18/750-1 with multiple cage configurations: high-strength pressed steel ribbon cages for standard duty, solid machined brass cages (M/CA) for heavy vibration and shock loads, or lightweight glass-fiber reinforced polyamide cages (TN9/TVP) for high acceleration and ultra-low noise.
In its sealed configuration (Open Type), CHG Bearing pre-charges N18/750-1 with premium wide-temperature lithium-complex or polyurea grease, calibrated to a 30%–35% cavity volume ratio. For open-type variants, synthetic PAO or refined mineral lubricating oils with appropriate EP (Extreme Pressure) additives should be circulated.
