HWAA10120HP4 206.375 mm 190.5 mm 15.875 mm 200.9 mm 195.97116 mm Frequently Asked Questions about HWAA10120HP4 Super Duplex Angular Contact Ball Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Beyond standard alloy steel, CHG Bearing can customize the HWAA10120HP4 Super Duplex Angular Contact Ball Bearings using AISI 440C stainless steel, black oxide coating, zinc-nickel plating, or hybrid ceramic (Si3N4) balls for applications involving chemical exposure, marine salt fog, or galvanic current hazards.
The Open / Single-Sided Sealed / Double-Sided Sealed engineered for HWAA10120HP4 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.
Quality starts with raw material selection: CHG Bearing crafts HWAA10120HP4 inner and outer rings from high-purity High-Quality Chrome Steel (GCr15/100Cr6). Our raw billets undergo vacuum degassing and secondary ESR (electroslag remelting) processes to drastically eliminate non-metallic sulfide and oxide inclusions, elevating subsurface contact fatigue resistance.
Engineered according to international ISO boundary plans, CHG Bearing supplies HWAA10120HP4 with a precision bore diameter (d) of 190.5 mm, an outside diameter (D) of 206.375 mm, and a nominal ring width (B) of 15.875 mm. This configuration yields an effective cross-sectional wall thickness of 7.9 mm and an envelope ratio (D/d) of 1.08, delivering compact rigidity for OEM machinery housings.
