7018 CDGATP/P4B 140 mm 90 mm 24 mm Frequently Asked Questions about 7018 CDGATP/P4B 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 7018 CDGATP/P4B 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 7018 CDGATP/P4B 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 (90 mm bore side) ensures perfect planar contact without edge binding.
To safeguard CHG Bearing 7018 CDGATP/P4B against fretting wear and false brinelling during transport or vibration, assemble mating surfaces (90 mm x 140 mm) using anti-fretting mounting paste. Maintaining strict alignment and avoiding prolonged static vibration will preserve raceway polish.
