Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Engineered according to international ISO boundary plans, CHG Bearing supplies FC5070220 with a precision bore diameter (d) of 250 mm, an outside diameter (D) of 350 mm, and a nominal ring width (B) of 220 mm. This configuration yields an effective cross-sectional wall thickness of 50.0 mm and an envelope ratio (D/d) of 1.4, delivering compact rigidity for OEM machinery housings.
For international ocean and air freight, CHG Bearing packs FC5070220 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.
The Open Type engineered for FC5070220 by CHG Bearing utilizes precision non-contact metal shields or reinforced NBR/FKM contact lip seals. This barrier prevents particulate ingress, washdown fluids, and abrasive dust from reaching the raceways while eliminating grease leakage under centrifugal forces.
In its sealed configuration (Open Type), CHG Bearing pre-charges FC5070220 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.
