HKD180XP0 482.6 mm 457.2 mm 12.7 mm Frequently Asked Questions about HKD180XP0 Thin Section Four-Point Contact Ball Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Engineered according to international ISO boundary plans, CHG Bearing supplies HKD180XP0 with a precision bore diameter (d) of 457.2 mm, an outside diameter (D) of 482.6 mm, and a nominal ring width (B) of 12.7 mm. This configuration yields an effective cross-sectional wall thickness of 12.7 mm and an envelope ratio (D/d) of 1.06, delivering compact rigidity for OEM machinery housings.
In its sealed configuration (Open), CHG Bearing pre-charges HKD180XP0 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.
Built for demanding industrial environments, the HKD180XP0 Thin Section Four-Point Contact Ball Bearings by CHG Bearing boasts a dynamic load rating (Cr) of standard dynamic and a static load threshold (C0r) of standard static. The optimized internal raceway geometry balances stress distribution, mitigating edge loading even when operating under peak mechanical stresses.
To match diverse operational dynamics, CHG Bearing supplies HKD180XP0 with multiple cage configurations: high-strength pressed steel ribbon cages for standard duty, solid machined brass cages (M/CA) for heavy vibration and shock loads, or lightweight glass-fiber reinforced polyamide cages (TN9/TVP) for high acceleration and ultra-low noise.
