313581AW/P5 365 mm 230 mm 266 mm 250 mm Frequently Asked Questions about 313581AW/P5 Four-Row Cylindrical Roller Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
In its sealed configuration (Open Type), CHG Bearing pre-charges 313581AW/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.
Following standard ISO 281 fatigue calculation guidelines, the nominal rating life (L10) of CHG Bearing 313581AW/P5 correlates its dynamic capacity (standard dynamic) with equivalent dynamic loads. In controlled industrial settings with proper contamination-free filtration, field data confirms continuous operational longevity exceeding 20,000 to 50,000 service hours.
Engineered according to international ISO boundary plans, CHG Bearing supplies 313581AW/P5 with a precision bore diameter (d) of 230 mm, an outside diameter (D) of 365 mm, and a nominal ring width (B) of 250 mm. This configuration yields an effective cross-sectional wall thickness of 67.5 mm and an envelope ratio (D/d) of 1.59, delivering compact rigidity for OEM machinery housings.
To ensure optimum performance of CHG Bearing 313581AW/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 230 mm bore. For the 365 mm outer ring, an H7 or J7 housing bore fit is recommended to eliminate creep while accommodating normal thermal gradient expansion.
