7012 CD/P4ADGC 95 mm 60 mm 36 mm Frequently Asked Questions about 7012 CD/P4ADGC Super-precision Angular Contact Ball Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
In its sealed configuration (Open Type), CHG Bearing pre-charges 7012 CD/P4ADGC 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.
Engineered according to international ISO boundary plans, CHG Bearing supplies 7012 CD/P4ADGC with a precision bore diameter (d) of 60 mm, an outside diameter (D) of 95 mm, and a nominal ring width (B) of 36 mm. This configuration yields an effective cross-sectional wall thickness of 17.5 mm and an envelope ratio (D/d) of 1.58, delivering compact rigidity for OEM machinery housings.
To ensure optimum performance of CHG Bearing 7012 CD/P4ADGC 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 60 mm bore. For the 95 mm outer ring, an H7 or J7 housing bore fit is recommended to eliminate creep while accommodating normal thermal gradient expansion.
To safeguard CHG Bearing 7012 CD/P4ADGC against fretting wear and false brinelling during transport or vibration, assemble mating surfaces (60 mm x 95 mm) using anti-fretting mounting paste. Maintaining strict alignment and avoiding prolonged static vibration will preserve raceway polish.
