Find key technical answers regarding dimensions, specifications, and replacement options for this model.
To safeguard CHG Bearing 71920 ACD/HCP4ADGC against fretting wear and false brinelling during transport or vibration, assemble mating surfaces (100 mm x 140 mm) using anti-fretting mounting paste. Maintaining strict alignment and avoiding prolonged static vibration will preserve raceway polish.
For international ocean and air freight, CHG Bearing packs 71920 ACD/HCP4ADGC 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.
In its sealed configuration (Open Type), CHG Bearing pre-charges 71920 ACD/HCP4ADGC 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.
Every production batch of CHG Bearing 71920 ACD/HCP4ADGC Super-precision Angular Contact Ball Bearings comes with complete traceability. Upon shipment, CHG Bearing can provide EN 10204 3.1 Material Test Reports (MTR), Certificates of Conformity (CoC), spectral chemical composition analysis, and dimensional inspection sheets.
