Find key technical answers regarding dimensions, specifications, and replacement options for this model.
In its sealed configuration (Open Type), CHG Bearing pre-charges 7215 ACD/P4ADFA 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 7215 ACD/P4ADFA against fretting wear and false brinelling during transport or vibration, assemble mating surfaces (75 mm x 130 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 7215 ACD/P4ADFA with a precision bore diameter (d) of 75 mm, an outside diameter (D) of 130 mm, and a nominal ring width (B) of 50 mm. This configuration yields an effective cross-sectional wall thickness of 27.5 mm and an envelope ratio (D/d) of 1.73, delivering compact rigidity for OEM machinery housings.
As standard production, CHG Bearing subjects 7215 ACD/P4ADFA to precision bainite or martensite quenching, offering dimensional stability up to 120°C (248°F). For high-heat processing equipment, CHG Bearing also supplies custom S0 (150°C), S1 (200°C), or S2 (250°C) stabilization heat treatments upon request to prevent residual austenite transformation.
