HWAA713HP4 31.75 mm 20.6375 mm 12.7 mm 28.17114 mm 24.2189 mm Frequently Asked Questions about HWAA713HP4 Super Duplex Angular Contact Ball Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
To ensure optimum performance of CHG Bearing HWAA713HP4 Super Duplex Angular Contact Ball Bearings under general rotational loads, our application engineers advise an inner-ring shaft tolerance of m5 or k5 for the 20.6375 mm bore. For the 31.75 mm outer ring, an H7 or J7 housing bore fit is recommended to eliminate creep while accommodating normal thermal gradient expansion.
The Open / Single-Sided Sealed / Double-Sided Sealed engineered for HWAA713HP4 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.
Absolutely. The CHG Bearing HWAA713HP4 Super Duplex Angular Contact Ball Bearings is a 1:1 direct interchange for renowned brands, matching part numbers: SKF HWAA713HP4, FAG HWAA713HP4, NSK HWAA713HP4. It shares identical envelope boundary dimensions, load capacities, and shaft fits, allowing instant drop-in replacement without retrofitting your machinery.
To match diverse operational dynamics, CHG Bearing supplies HWAA713HP4 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.
