S71917 ACDGA/P4A 120 mm 85 mm 18 mm Frequently Asked Questions about S71917 ACDGA/P4A Super-precision Angular Contact Ball Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
The Non-contact Seal engineered for S71917 ACDGA/P4A 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.
As standard production, CHG Bearing subjects S71917 ACDGA/P4A 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.
Absolutely. The CHG Bearing S71917 ACDGA/P4A Super-precision Angular Contact Ball Bearings is a 1:1 direct interchange for renowned brands, matching part numbers: SKF S71917 ACDGA/P4A, FAG S71917 ACDGA/P4A, NSK S71917 ACDGA/P4A. It shares identical envelope boundary dimensions, load capacities, and shaft fits, allowing instant drop-in replacement without retrofitting your machinery.
Beyond standard alloy steel, CHG Bearing can customize the S71917 ACDGA/P4A Super-precision Angular Contact Ball Bearings 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.
