7009 ACE/HCP4ADGA 75 mm 45 mm 32 mm Frequently Asked Questions about 7009 ACE/HCP4ADGA Super-precision Angular Contact Ball Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Each 7009 ACE/HCP4ADGA 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.
Absolutely. The CHG Bearing 7009 ACE/HCP4ADGA Super-precision Angular Contact Ball Bearings is a 1:1 direct interchange for renowned brands, matching part numbers: SKF 7009 ACE/HCP4ADGA, FAG 7009 ACE/HCP4ADGA, NSK 7009 ACE/HCP4ADGA. It shares identical envelope boundary dimensions, load capacities, and shaft fits, allowing instant drop-in replacement without retrofitting your machinery.
Engineered according to international ISO boundary plans, CHG Bearing supplies 7009 ACE/HCP4ADGA 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.
Quality starts with raw material selection: CHG Bearing crafts 7009 ACE/HCP4ADGA 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.
