NU2326X3/P5 280 mm 130 mm 120 mm 167 mm Frequently Asked Questions about NU2326X3/P5 Single Row Cylindrical Roller Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Engineered according to international ISO boundary plans, CHG Bearing supplies NU2326X3/P5 with a precision bore diameter (d) of 130 mm, an outside diameter (D) of 280 mm, and a nominal ring width (B) of 120 mm. This configuration yields an effective cross-sectional wall thickness of 75.0 mm and an envelope ratio (D/d) of 2.15, delivering compact rigidity for OEM machinery housings.
To ensure optimum performance of CHG Bearing NU2326X3/P5 Single Row Cylindrical Roller Bearings under general rotational loads, our application engineers advise an inner-ring shaft tolerance of m5 or k5 for the 130 mm bore. For the 280 mm outer ring, an H7 or J7 housing bore fit is recommended to eliminate creep while accommodating normal thermal gradient expansion.
In its sealed configuration (Open Type), CHG Bearing pre-charges NU2326X3/P5 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.
Beyond standard alloy steel, CHG Bearing can customize the NU2326X3/P5 Single Row Cylindrical Roller Bearings using AISI 440C stainless steel, black oxide coating, zinc-nickel plating, or hybrid ceramic (Si3N4) balls for applications involving chemical exposure, marine salt fog, or galvanic current hazards.
