Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Standard batches of CHG Bearing HKA040AP0 conform strictly to ISO Class Normal (ABEC-1). For high-precision machine tool spindles, gearboxes, or robotics requiring tighter runouts, CHG Bearing can provide custom batches graded to ISO Class 6 (P6/ABEC-3) or ISO Class 5 (P5/ABEC-5) with 100% micrometer verification.
Sourcing HKA040AP0 directly from CHG Bearing eliminates intermediate brokerage markups while granting you factory-direct engineering backup, rigorous ISO-certified quality assurance, competitive volume wholesale pricing, and dependable supply chain stability for Thin Section Angular Contact Ball Bearings.
Engineered according to international ISO boundary plans, CHG Bearing supplies HKA040AP0 with a precision bore diameter (d) of 101.6 mm, an outside diameter (D) of 114.3 mm, and a nominal ring width (B) of 6.35 mm. This configuration yields an effective cross-sectional wall thickness of 6.4 mm and an envelope ratio (D/d) of 1.12, delivering compact rigidity for OEM machinery housings.
Quality starts with raw material selection: CHG Bearing crafts HKA040AP0 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.
