HWAA1076HP4 136.525 mm 120.65 mm 15.875 mm 131.05 mm 126.12116 mm Frequently Asked Questions about HWAA1076HP4 Super Duplex Angular Contact Ball Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Engineered according to international ISO boundary plans, CHG Bearing supplies HWAA1076HP4 with a precision bore diameter (d) of 120.65 mm, an outside diameter (D) of 136.525 mm, and a nominal ring width (B) of 15.875 mm. This configuration yields an effective cross-sectional wall thickness of 7.9 mm and an envelope ratio (D/d) of 1.13, delivering compact rigidity for OEM machinery housings.
Built for demanding industrial environments, the HWAA1076HP4 Super Duplex Angular Contact Ball Bearings by CHG Bearing boasts a dynamic load rating (Cr) of standard dynamic and a static load threshold (C0r) of standard static. The optimized internal raceway geometry balances stress distribution, mitigating edge loading even when operating under peak mechanical stresses.
Quality starts with raw material selection: CHG Bearing crafts HWAA1076HP4 inner and outer rings from high-purity High-Quality Chrome Steel (GCr15/100Cr6). Our raw billets undergo vacuum degassing and secondary ESR (electroslag remelting) processes to drastically eliminate non-metallic sulfide and oxide inclusions, elevating subsurface contact fatigue resistance.
The Open / Single-Sided Sealed / Double-Sided Sealed engineered for HWAA1076HP4 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.
