Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Built for demanding industrial environments, the HWAA856HP4 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.
In its sealed configuration (Open / Single-Sided Sealed / Double-Sided Sealed), CHG Bearing pre-charges HWAA856HP4 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.
To ensure optimum performance of CHG Bearing HWAA856HP4 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 88.9 mm bore. For the 101.6 mm outer ring, an H7 or J7 housing bore fit is recommended to eliminate creep while accommodating normal thermal gradient expansion.
Following standard ISO 281 fatigue calculation guidelines, the nominal rating life (L10) of CHG Bearing HWAA856HP4 correlates its dynamic capacity (standard dynamic) with equivalent dynamic loads. In controlled industrial settings with proper contamination-free filtration, field data confirms continuous operational longevity exceeding 20,000 to 50,000 service hours.
