Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Engineered according to international ISO boundary plans, CHG Bearing supplies 7015 ACE/HCP4ADT with a precision bore diameter (d) of 75 mm, an outside diameter (D) of 115 mm, and a nominal ring width (B) of 40 mm. This configuration yields an effective cross-sectional wall thickness of 20.0 mm and an envelope ratio (D/d) of 1.53, delivering compact rigidity for OEM machinery housings.
To ensure optimum performance of CHG Bearing 7015 ACE/HCP4ADT 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 75 mm bore. For the 115 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 7015 ACE/HCP4ADT against fretting wear and false brinelling during transport or vibration, assemble mating surfaces (75 mm x 115 mm) using anti-fretting mounting paste. Maintaining strict alignment and avoiding prolonged static vibration will preserve raceway polish.
In its sealed configuration (Open Type), CHG Bearing pre-charges 7015 ACE/HCP4ADT 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.
