Find key technical answers regarding dimensions, specifications, and replacement options for this model.
In its sealed configuration (Open Type), CHG Bearing pre-charges 7220 ACD/P4ADBA 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 7220 ACD/P4ADBA with a precision bore diameter (d) of 100 mm, an outside diameter (D) of 180 mm, and a nominal ring width (B) of 68 mm. This configuration yields an effective cross-sectional wall thickness of 40.0 mm and an envelope ratio (D/d) of 1.8, delivering compact rigidity for OEM machinery housings.
For international ocean and air freight, CHG Bearing packs 7220 ACD/P4ADBA with industrial VCI anti-corrosion barrier wrapping, sealed polybags, individual cartons, and fumigated ocean-worthy wooden crates. This multi-layer barrier guarantees rust-free storage for a minimum shelf life of 24 to 36 months.
