7214 ACD/P4ADGB 125 mm 70 mm 48 mm Frequently Asked Questions about 7214 ACD/P4ADGB Super-precision Angular Contact Ball Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Beyond standard alloy steel, CHG Bearing can customize the 7214 ACD/P4ADGB 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.
The Open Type engineered for 7214 ACD/P4ADGB 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.
To safeguard CHG Bearing 7214 ACD/P4ADGB against fretting wear and false brinelling during transport or vibration, assemble mating surfaces (70 mm x 125 mm) using anti-fretting mounting paste. Maintaining strict alignment and avoiding prolonged static vibration will preserve raceway polish.
Engineered according to international ISO boundary plans, CHG Bearing supplies 7214 ACD/P4ADGB with a precision bore diameter (d) of 70 mm, an outside diameter (D) of 125 mm, and a nominal ring width (B) of 48 mm. This configuration yields an effective cross-sectional wall thickness of 27.5 mm and an envelope ratio (D/d) of 1.79, delivering compact rigidity for OEM machinery housings.
