Find key technical answers regarding dimensions, specifications, and replacement options for this model.
To safeguard CHG Bearing NU3076 against fretting wear and false brinelling during transport or vibration, assemble mating surfaces (380 mm x 560 mm) using anti-fretting mounting paste. Maintaining strict alignment and avoiding prolonged static vibration will preserve raceway polish.
Sourcing NU3076 directly from CHG Bearing eliminates intermediate brokerage markups while granting you factory-direct engineering backup, rigorous ISO-certified quality assurance, competitive volume wholesale pricing, and dependable supply chain stability for Single Row Cylindrical Roller Bearings.
Built for demanding industrial environments, the NU3076 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.
Engineered according to international ISO boundary plans, CHG Bearing supplies NU3076 with a precision bore diameter (d) of 380 mm, an outside diameter (D) of 560 mm, and a nominal ring width (B) of 135 mm. This configuration yields an effective cross-sectional wall thickness of 90.0 mm and an envelope ratio (D/d) of 1.47, delivering compact rigidity for OEM machinery housings.
