313822/P5 390 mm 280 mm 312 mm 220 mm Frequently Asked Questions about 313822/P5 Four-Row Cylindrical Roller Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
The CHG Bearing 313822/P5 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.
In its sealed configuration (Open Type), CHG Bearing pre-charges 313822/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.
Engineered according to international ISO boundary plans, CHG Bearing supplies 313822/P5 with a precision bore diameter (d) of 280 mm, an outside diameter (D) of 390 mm, and a nominal ring width (B) of 220 mm. This configuration yields an effective cross-sectional wall thickness of 55.0 mm and an envelope ratio (D/d) of 1.39, delivering compact rigidity for OEM machinery housings.
To ensure optimum performance of CHG Bearing 313822/P5 Four-Row Cylindrical Roller Bearings under general rotational loads, our application engineers advise an inner-ring shaft tolerance of m5 or k5 for the 280 mm bore. For the 390 mm outer ring, an H7 or J7 housing bore fit is recommended to eliminate creep while accommodating normal thermal gradient expansion.
