Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Sourcing 71952 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 Angular Contact Ball Bearings（718 / 719 SERIES）.
Each 71952 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.
Beyond standard alloy steel, CHG Bearing can customize the 71952 Angular Contact Ball Bearings（718 / 719 SERIES） 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.
Following standard ISO 281 fatigue calculation guidelines, the nominal rating life (L10) of CHG Bearing 71952 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.
