Sourcing HWAA840HP4 directly from CHG Bearing eliminates intermediate brokerage markups while granting you factory-direct engineering backup, rigorous ISO-certified quality assurance, competitive volume wholesale pricing, and dependable supply chain stability for Super Duplex Angular Contact Ball Bearings.
Engineered according to international ISO boundary plans, CHG Bearing supplies HWAA840HP4 with a precision bore diameter (d) of 63.5 mm, an outside diameter (D) of 76.2 mm, and a nominal ring width (B) of 12.7 mm. This configuration yields an effective cross-sectional wall thickness of 6.4 mm and an envelope ratio (D/d) of 1.2, delivering compact rigidity for OEM machinery housings.
Every production batch of CHG Bearing HWAA840HP4 Super Duplex Angular Contact Ball Bearings comes with complete traceability. Upon shipment, CHG Bearing can provide EN 10204 3.1 Material Test Reports (MTR), Certificates of Conformity (CoC), spectral chemical composition analysis, and dimensional inspection sheets.
To ensure optimum performance of CHG Bearing HWAA840HP4 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 63.5 mm bore. For the 76.2 mm outer ring, an H7 or J7 housing bore fit is recommended to eliminate creep while accommodating normal thermal gradient expansion.
