7200 CD/P4ADGA 30 mm 10 mm 18 mm Frequently Asked Questions about 7200 CD/P4ADGA Super-precision Angular Contact Ball Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
To ensure optimum performance of CHG Bearing 7200 CD/P4ADGA Super-precision Angular Contact Ball Bearings under general rotational loads, our application engineers advise an inner-ring shaft tolerance of m5 or k5 for the 10 mm bore. For the 30 mm outer ring, an H7 or J7 housing bore fit is recommended to eliminate creep while accommodating normal thermal gradient expansion.
Beyond standard alloy steel, CHG Bearing can customize the 7200 CD/P4ADGA 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.
In its sealed configuration (Open Type), CHG Bearing pre-charges 7200 CD/P4ADGA with premium wide-temperature lithium-complex or polyurea grease, calibrated to a 30%–35% cavity volume ratio. For open-type variants, synthetic PAO or refined mineral lubricating oils with appropriate EP (Extreme Pressure) additives should be circulated.
To safeguard CHG Bearing 7200 CD/P4ADGA against fretting wear and false brinelling during transport or vibration, assemble mating surfaces (10 mm x 30 mm) using anti-fretting mounting paste. Maintaining strict alignment and avoiding prolonged static vibration will preserve raceway polish.
