Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Engineered according to international ISO boundary plans, CHG Bearing supplies HWAD1072HP4 with a precision bore diameter (d) of 114.3 mm, an outside diameter (D) of 130.175 mm, and a nominal ring width (B) of 12.7 mm. This configuration yields an effective cross-sectional wall thickness of 7.9 mm and an envelope ratio (D/d) of 1.14, delivering compact rigidity for OEM machinery housings.
In its sealed configuration (Open / Single-Sided Sealed / Double-Sided Sealed), CHG Bearing pre-charges HWAD1072HP4 with premium wide-temperature lithium-complex or polyurea grease, calibrated to a 30%–35% cavity volume ratio. For open-type variants, synthetic PAO or refined mineral lubricating oils with appropriate EP (Extreme Pressure) additives should be circulated.
Yes, 100% of HWAD1072HP4 Super Duplex Angular Contact Ball Bearings leaving CHG Bearing production lines are subjected to multi-frequency Anderometer sound testing. All units satisfy baseline Z1V1 levels, with dedicated quiet-running electric motor quality (EMQ) lots certified to Z2V2 and Z3V3 standards for silent machinery integration.
As standard production, CHG Bearing subjects HWAD1072HP4 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.
