S7215 ACD/P4ADGA 130 mm 75 mm 50 mm Frequently Asked Questions about S7215 ACD/P4ADGA Super-precision Angular Contact Ball Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Engineered according to international ISO boundary plans, CHG Bearing supplies S7215 ACD/P4ADGA 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.
To safeguard CHG Bearing S7215 ACD/P4ADGA 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.
To ensure optimum performance of CHG Bearing S7215 ACD/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 75 mm bore. For the 130 mm outer ring, an H7 or J7 housing bore fit is recommended to eliminate creep while accommodating normal thermal gradient expansion.
Model S7215 ACD/P4ADGA is manufactured by CHG Bearing in standard Normal clearance (CN) for ambient temperature transmission, and C3 or C4 clearance for heavy duty applications. C3 clearance compensates for radial shrinkage caused by tight shaft press-fits (bore 75 mm) and steep thermal gradients between inner and outer rings.
