HJU080XP0 222.25 mm 203.2 mm 12.7 mm Frequently Asked Questions about HJU080XP0 Thin Section Four-Point Contact Ball Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
In its sealed configuration (Sealed), CHG Bearing pre-charges HJU080XP0 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.
For international ocean and air freight, CHG Bearing packs HJU080XP0 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.
Each HJU080XP0 produced in CHG Bearing manufacturing facilities features accurately profiled corner chamfers complying with DIN 5412 / ISO standard corner radii. When designing mating shafts and housing shoulders, machining an undercut or fillet radius strictly within the inner ring clearance limit (203.2 mm bore side) ensures perfect planar contact without edge binding.
To safeguard CHG Bearing HJU080XP0 against fretting wear and false brinelling during transport or vibration, assemble mating surfaces (203.2 mm x 222.25 mm) using anti-fretting mounting paste. Maintaining strict alignment and avoiding prolonged static vibration will preserve raceway polish.
