N320R/P5 215 mm 100 mm 191.5 mm 47 mm Frequently Asked Questions about N320R/P5 Single Row Cylindrical Roller Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
To ensure optimum performance of CHG Bearing N320R/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 100 mm bore. For the 215 mm outer ring, an H7 or J7 housing bore fit is recommended to eliminate creep while accommodating normal thermal gradient expansion.
Engineered according to international ISO boundary plans, CHG Bearing supplies N320R/P5 with a precision bore diameter (d) of 100 mm, an outside diameter (D) of 215 mm, and a nominal ring width (B) of 47 mm. This configuration yields an effective cross-sectional wall thickness of 57.5 mm and an envelope ratio (D/d) of 2.15, delivering compact rigidity for OEM machinery housings.
Standard batches of CHG Bearing N320R/P5 conform strictly to ISO Class Normal (ABEC-1). For high-precision machine tool spindles, gearboxes, or robotics requiring tighter runouts, CHG Bearing can provide custom batches graded to ISO Class 6 (P6/ABEC-3) or ISO Class 5 (P5/ABEC-5) with 100% micrometer verification.
In its sealed configuration (Open Type), CHG Bearing pre-charges N320R/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.
