Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Engineered according to international ISO boundary plans, CHG Bearing supplies HWAD424HP4 with a precision bore diameter (d) of 38.1 mm, an outside diameter (D) of 44.45 mm, and a nominal ring width (B) of 7.937 mm. This configuration yields an effective cross-sectional wall thickness of 3.2 mm and an envelope ratio (D/d) of 1.17, delivering compact rigidity for OEM machinery housings.
Each HWAD424HP4 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 (38.1 mm bore side) ensures perfect planar contact without edge binding.
Every production batch of CHG Bearing HWAD424HP4 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 HWAD424HP4 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 38.1 mm bore. For the 44.45 mm outer ring, an H7 or J7 housing bore fit is recommended to eliminate creep while accommodating normal thermal gradient expansion.
