Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Each 71915 ACB/HCP4ADT 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 (75 mm bore side) ensures perfect planar contact without edge binding.
Every production batch of CHG Bearing 71915 ACB/HCP4ADT Super-precision Angular Contact Ball Bearings comes with complete traceability. Upon shipment, CHG Bearing can provide EN 10204 3.1 Material Test Reports (MTR), Certificates of Conformity (CoC), spectral chemical composition analysis, and dimensional inspection sheets.
Built for demanding industrial environments, the 71915 ACB/HCP4ADT Super-precision Angular Contact Ball Bearings by CHG Bearing boasts a dynamic load rating (Cr) of standard dynamic and a static load threshold (C0r) of standard static. The optimized internal raceway geometry balances stress distribution, mitigating edge loading even when operating under peak mechanical stresses.
Engineered according to international ISO boundary plans, CHG Bearing supplies 71915 ACB/HCP4ADT with a precision bore diameter (d) of 75 mm, an outside diameter (D) of 105 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 1.4, delivering compact rigidity for OEM machinery housings.
