S71913 ACD/HCP4ADBC 90 mm 65 mm 26 mm Frequently Asked Questions about S71913 ACD/HCP4ADBC Super-precision Angular Contact Ball Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Engineered according to international ISO boundary plans, CHG Bearing supplies S71913 ACD/HCP4ADBC with a precision bore diameter (d) of 65 mm, an outside diameter (D) of 90 mm, and a nominal ring width (B) of 26 mm. This configuration yields an effective cross-sectional wall thickness of 12.5 mm and an envelope ratio (D/d) of 1.38, delivering compact rigidity for OEM machinery housings.
Each S71913 ACD/HCP4ADBC 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 (65 mm bore side) ensures perfect planar contact without edge binding.
Yes, CHG Bearing works closely with industrial OEMs and brand distributors. We offer turnkey custom engineering for S71913 ACD/HCP4ADBC, including laser-etched customer logos, custom internal radial clearances, specialized grease formulations, and bespoke protective packaging.
As standard production, CHG Bearing subjects S71913 ACD/HCP4ADBC to precision bainite or martensite quenching, offering dimensional stability up to 120°C (248°F). For high-heat processing equipment, CHG Bearing also supplies custom S0 (150°C), S1 (200°C), or S2 (250°C) stabilization heat treatments upon request to prevent residual austenite transformation.
