HWAA1072HP4 130.175 mm 114.3 mm 15.875 mm 124.7 mm 119.77116 mm Frequently Asked Questions about HWAA1072HP4 Super Duplex Angular Contact Ball Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
The Open / Single-Sided Sealed / Double-Sided Sealed engineered for HWAA1072HP4 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.
As standard production, CHG Bearing subjects HWAA1072HP4 to precision bainite or martensite quenching, offering dimensional stability up to 120°C (248°F). For high-heat processing equipment, CHG Bearing also supplies custom S0 (150°C), S1 (200°C), or S2 (250°C) stabilization heat treatments upon request to prevent residual austenite transformation.
When fitting HWAA1072HP4 over a 114.3 mm shaft, CHG Bearing strictly recommends uniform induction heating (controlled between 90°C and 110°C) or precision hydraulic press sleeves. Under no circumstances should direct impact blows be struck against the rings or cage, as shock loads cause brinelling indents and premature spalling.
Absolutely. The CHG Bearing HWAA1072HP4 Super Duplex Angular Contact Ball Bearings is a 1:1 direct interchange for renowned brands, matching part numbers: SKF HWAA1072HP4, FAG HWAA1072HP4, NSK HWAA1072HP4. It shares identical envelope boundary dimensions, load capacities, and shaft fits, allowing instant drop-in replacement without retrofitting your machinery.
