7206 CD/P4ADBA 62 mm 30 mm 32 mm Frequently Asked Questions about 7206 CD/P4ADBA Super-precision Angular Contact Ball Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
As standard production, CHG Bearing subjects 7206 CD/P4ADBA 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.
Engineered according to international ISO boundary plans, CHG Bearing supplies 7206 CD/P4ADBA with a precision bore diameter (d) of 30 mm, an outside diameter (D) of 62 mm, and a nominal ring width (B) of 32 mm. This configuration yields an effective cross-sectional wall thickness of 16.0 mm and an envelope ratio (D/d) of 2.07, delivering compact rigidity for OEM machinery housings.
In its sealed configuration (Open Type), CHG Bearing pre-charges 7206 CD/P4ADBA 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 ensure optimum performance of CHG Bearing 7206 CD/P4ADBA 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 30 mm bore. For the 62 mm outer ring, an H7 or J7 housing bore fit is recommended to eliminate creep while accommodating normal thermal gradient expansion.
