Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Each 7009 ACD/P4ADBC 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 (45 mm bore side) ensures perfect planar contact without edge binding.
Engineered according to international ISO boundary plans, CHG Bearing supplies 7009 ACD/P4ADBC with a precision bore diameter (d) of 45 mm, an outside diameter (D) of 75 mm, and a nominal ring width (B) of 32 mm. This configuration yields an effective cross-sectional wall thickness of 15.0 mm and an envelope ratio (D/d) of 1.67, delivering compact rigidity for OEM machinery housings.
As a primary manufacturer, CHG Bearing supports both trial batch evaluations and container-load supply for 7009 ACD/P4ADBC. Standard catalog sizes are stocked for rapid 3–7 day dispatch, while high-volume OEM production runs typically dispatch within 30–45 days.
Beyond standard alloy steel, CHG Bearing can customize the 7009 ACD/P4ADBC Super-precision Angular Contact Ball Bearings using AISI 440C stainless steel, black oxide coating, zinc-nickel plating, or hybrid ceramic (Si3N4) balls for applications involving chemical exposure, marine salt fog, or galvanic current hazards.
