Find key technical answers regarding dimensions, specifications, and replacement options for this model.
As a primary manufacturer, CHG Bearing supports both trial batch evaluations and container-load supply for HKC040AP4. Standard catalog sizes are stocked for rapid 3–7 day dispatch, while high-volume OEM production runs typically dispatch within 30–45 days.
Built for demanding industrial environments, the HKC040AP4 Thin Section 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 HKC040AP4 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 (101.6 mm bore side) ensures perfect planar contact without edge binding.
Engineered according to international ISO boundary plans, CHG Bearing supplies HKC040AP4 with a precision bore diameter (d) of 101.6 mm, an outside diameter (D) of 120.65 mm, and a nominal ring width (B) of 9.525 mm. This configuration yields an effective cross-sectional wall thickness of 9.5 mm and an envelope ratio (D/d) of 1.19, delivering compact rigidity for OEM machinery housings.
