Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Sourcing 7052 ACD/P4ADGB 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 Super-precision Angular Contact Ball Bearings.
Each 7052 ACD/P4ADGB 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 (260 mm bore side) ensures perfect planar contact without edge binding.
Engineered according to international ISO boundary plans, CHG Bearing supplies 7052 ACD/P4ADGB with a precision bore diameter (d) of 260 mm, an outside diameter (D) of 400 mm, and a nominal ring width (B) of 130 mm. This configuration yields an effective cross-sectional wall thickness of 70.0 mm and an envelope ratio (D/d) of 1.54, delivering compact rigidity for OEM machinery housings.
Following standard ISO 281 fatigue calculation guidelines, the nominal rating life (L10) of CHG Bearing 7052 ACD/P4ADGB correlates its dynamic capacity (standard dynamic) with equivalent dynamic loads. In controlled industrial settings with proper contamination-free filtration, field data confirms continuous operational longevity exceeding 20,000 to 50,000 service hours.
