Find key technical answers regarding dimensions, specifications, and replacement options for this model.
To safeguard CHG Bearing 71814 ACDGA/HCP4 against fretting wear and false brinelling during transport or vibration, assemble mating surfaces (70 mm x 90 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 71814 ACDGA/HCP4 with a precision bore diameter (d) of 70 mm, an outside diameter (D) of 90 mm, and a nominal ring width (B) of 10 mm. This configuration yields an effective cross-sectional wall thickness of 10.0 mm and an envelope ratio (D/d) of 1.29, delivering compact rigidity for OEM machinery housings.
Beyond standard alloy steel, CHG Bearing can customize the 71814 ACDGA/HCP4 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.
Each 71814 ACDGA/HCP4 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 (70 mm bore side) ensures perfect planar contact without edge binding.
