HKB090AP4 244.475 mm 228.6 mm 7.9375 mm Frequently Asked Questions about HKB090AP4 Thin Section Angular Contact Ball Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
In its sealed configuration (Open), CHG Bearing pre-charges HKB090AP4 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 HKB090AP4 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 HKB090AP4 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 (228.6 mm bore side) ensures perfect planar contact without edge binding.
Engineered according to international ISO boundary plans, CHG Bearing supplies HKB090AP4 with a precision bore diameter (d) of 228.6 mm, an outside diameter (D) of 244.475 mm, and a nominal ring width (B) of 7.9375 mm. This configuration yields an effective cross-sectional wall thickness of 7.9 mm and an envelope ratio (D/d) of 1.07, delivering compact rigidity for OEM machinery housings.
