Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Engineered according to international ISO boundary plans, CHG Bearing supplies NU3880 with a precision bore diameter (d) of 400 mm, an outside diameter (D) of 500 mm, and a nominal ring width (B) of 75 mm. This configuration yields an effective cross-sectional wall thickness of 50.0 mm and an envelope ratio (D/d) of 1.25, delivering compact rigidity for OEM machinery housings.
To ensure optimum performance of CHG Bearing NU3880 Single Row Cylindrical Roller Bearings under general rotational loads, our application engineers advise an inner-ring shaft tolerance of m5 or k5 for the 400 mm bore. For the 500 mm outer ring, an H7 or J7 housing bore fit is recommended to eliminate creep while accommodating normal thermal gradient expansion.
The CHG Bearing NU3880 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.
Sourcing NU3880 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.
