Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Engineered according to international ISO boundary plans, CHG Bearing supplies 7004 ACD/P4ADBD with a precision bore diameter (d) of 20 mm, an outside diameter (D) of 42 mm, and a nominal ring width (B) of 24 mm. This configuration yields an effective cross-sectional wall thickness of 11.0 mm and an envelope ratio (D/d) of 2.1, delivering compact rigidity for OEM machinery housings.
Absolutely. The CHG Bearing 7004 ACD/P4ADBD Super-precision Angular Contact Ball Bearings is a 1:1 direct interchange for renowned brands, matching part numbers: SKF 7004 ACD/P4ADBD, FAG 7004 ACD/P4ADBD, NSK 7004 ACD/P4ADBD. It shares identical envelope boundary dimensions, load capacities, and shaft fits, allowing instant drop-in replacement without retrofitting your machinery.
Each 7004 ACD/P4ADBD 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 (20 mm bore side) ensures perfect planar contact without edge binding.
Quality starts with raw material selection: CHG Bearing crafts 7004 ACD/P4ADBD 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.
