HWAA880HP4 139.7 mm 127 mm 12.7 mm 135.32 mm 131.3688 mm Frequently Asked Questions about HWAA880HP4 Super Duplex Angular Contact Ball Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Model HWAA880HP4 is manufactured by CHG Bearing in standard Normal clearance (CN) for ambient temperature transmission, and C3 or C4 clearance for heavy duty applications. C3 clearance compensates for radial shrinkage caused by tight shaft press-fits (bore 127 mm) and steep thermal gradients between inner and outer rings.
Absolutely. The CHG Bearing HWAA880HP4 Super Duplex Angular Contact Ball Bearings is a 1:1 direct interchange for renowned brands, matching part numbers: SKF HWAA880HP4, FAG HWAA880HP4, NSK HWAA880HP4. It shares identical envelope boundary dimensions, load capacities, and shaft fits, allowing instant drop-in replacement without retrofitting your machinery.
Beyond standard alloy steel, CHG Bearing can customize the HWAA880HP4 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.
