HKC080CP4 222.25 mm 203.2 mm 9.525 mm Frequently Asked Questions about HKC080CP4 Thin Section Deep Groove Ball Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
To ensure optimum performance of CHG Bearing HKC080CP4 Thin Section Deep Groove Ball Bearings under general rotational loads, our application engineers advise an inner-ring shaft tolerance of m5 or k5 for the 203.2 mm bore. For the 222.25 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 HKC080CP4 with a precision bore diameter (d) of 203.2 mm, an outside diameter (D) of 222.25 mm, and a nominal ring width (B) of 9.525 mm. This configuration yields an effective cross-sectional wall thickness of 9.5 mm and an envelope ratio (D/d) of 1.09, delivering compact rigidity for OEM machinery housings.
Quality starts with raw material selection: CHG Bearing crafts HKC080CP4 inner and outer rings from high-purity High-Quality Chrome Steel (GCr15/100Cr6). Our raw billets undergo vacuum degassing and secondary ESR (electroslag remelting) processes to drastically eliminate non-metallic sulfide and oxide inclusions, elevating subsurface contact fatigue resistance.
In its sealed configuration (Open), CHG Bearing pre-charges HKC080CP4 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.
