Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Yes, 100% of 71803 ACDGA/P4 Super-precision Angular Contact Ball Bearings leaving CHG Bearing production lines are subjected to multi-frequency Anderometer sound testing. All units satisfy baseline Z1V1 levels, with dedicated quiet-running electric motor quality (EMQ) lots certified to Z2V2 and Z3V3 standards for silent machinery integration.
As standard production, CHG Bearing subjects 71803 ACDGA/P4 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.
The Open Type engineered for 71803 ACDGA/P4 by CHG Bearing utilizes precision non-contact metal shields or reinforced NBR/FKM contact lip seals. This barrier prevents particulate ingress, washdown fluids, and abrasive dust from reaching the raceways while eliminating grease leakage under centrifugal forces.
Engineered according to international ISO boundary plans, CHG Bearing supplies 71803 ACDGA/P4 with a precision bore diameter (d) of 17 mm, an outside diameter (D) of 26 mm, and a nominal ring width (B) of 5 mm. This configuration yields an effective cross-sectional wall thickness of 4.5 mm and an envelope ratio (D/d) of 1.53, delivering compact rigidity for OEM machinery housings.
