Find key technical answers regarding dimensions, specifications, and replacement options for this model.
To ensure optimum performance of CHG Bearing HWAA725HP4 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 39.6875 mm bore. For the 50.8 mm outer ring, an H7 or J7 housing bore fit is recommended to eliminate creep while accommodating normal thermal gradient expansion.
Engineered according to international ISO boundary plans, CHG Bearing supplies HWAA725HP4 with a precision bore diameter (d) of 39.6875 mm, an outside diameter (D) of 50.8 mm, and a nominal ring width (B) of 12.7 mm. This configuration yields an effective cross-sectional wall thickness of 5.6 mm and an envelope ratio (D/d) of 1.28, delivering compact rigidity for OEM machinery housings.
Built for demanding industrial environments, the HWAA725HP4 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.
Each HWAA725HP4 produced in CHG Bearing manufacturing facilities features accurately profiled corner chamfers complying with DIN 5412 / ISO standard corner radii. When designing mating shafts and housing shoulders, machining an undercut or fillet radius strictly within the inner ring clearance limit (39.6875 mm bore side) ensures perfect planar contact without edge binding.
