Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Engineered according to international ISO boundary plans, CHG Bearing supplies 7216 CD/P4ADGB with a precision bore diameter (d) of 80 mm, an outside diameter (D) of 140 mm, and a nominal ring width (B) of 52 mm. This configuration yields an effective cross-sectional wall thickness of 30.0 mm and an envelope ratio (D/d) of 1.75, delivering compact rigidity for OEM machinery housings.
To safeguard CHG Bearing 7216 CD/P4ADGB against fretting wear and false brinelling during transport or vibration, assemble mating surfaces (80 mm x 140 mm) using anti-fretting mounting paste. Maintaining strict alignment and avoiding prolonged static vibration will preserve raceway polish.
Every production batch of CHG Bearing 7216 CD/P4ADGB Super-precision Angular Contact Ball Bearings comes with complete traceability. Upon shipment, CHG Bearing can provide EN 10204 3.1 Material Test Reports (MTR), Certificates of Conformity (CoC), spectral chemical composition analysis, and dimensional inspection sheets.
Following standard ISO 281 fatigue calculation guidelines, the nominal rating life (L10) of CHG Bearing 7216 CD/P4ADGB correlates its dynamic capacity (standard dynamic) with equivalent dynamic loads. In controlled industrial settings with proper contamination-free filtration, field data confirms continuous operational longevity exceeding 20,000 to 50,000 service hours.
