Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Built for demanding industrial environments, the NU364 Single Row Cylindrical Roller Bearings by CHG Bearing boasts a dynamic load rating (Cr) of standard dynamic and a static load threshold (C0r) of standard static. The optimized internal raceway geometry balances stress distribution, mitigating edge loading even when operating under peak mechanical stresses.
The CHG Bearing NU364 is rated for limiting speeds up to standard rated RPM under forced oil-mist or circulating oil lubrication regimes. When lubricated with factory-filled synthetic high-speed grease, safe continuous velocity is maintained at approximately 75% to 85% of the maximum nominal limit, preventing thermal runaway.
Engineered according to international ISO boundary plans, CHG Bearing supplies NU364 with a precision bore diameter (d) of 320 mm, an outside diameter (D) of 670 mm, and a nominal ring width (B) of 112 mm. This configuration yields an effective cross-sectional wall thickness of 175.0 mm and an envelope ratio (D/d) of 2.09, delivering compact rigidity for OEM machinery housings.
Following standard ISO 281 fatigue calculation guidelines, the nominal rating life (L10) of CHG Bearing NU364 correlates its dynamic capacity (standard dynamic) with equivalent dynamic loads. In controlled industrial settings with proper contamination-free filtration, field data confirms continuous operational longevity exceeding 20,000 to 50,000 service hours.
