Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Every production batch of CHG Bearing 71992P4 Angular Contact Ball Bearings（718 / 719 SERIES） 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.
Engineered according to international ISO boundary plans, CHG Bearing supplies 71992P4 with a precision bore diameter (d) of 460 mm, an outside diameter (D) of 620 mm, and a nominal ring width (B) of 74 mm. This configuration yields an effective cross-sectional wall thickness of 80.0 mm and an envelope ratio (D/d) of 1.35, delivering compact rigidity for OEM machinery housings.
Model 71992P4 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 460 mm) and steep thermal gradients between inner and outer rings.
Built for demanding industrial environments, the 71992P4 Angular Contact Ball Bearings（718 / 719 SERIES） by CHG Bearing boasts a dynamic load rating (Cr) of standard dynamic and a static load threshold (C0r) of standard static. The optimized internal raceway geometry balances stress distribution, mitigating edge loading even when operating under peak mechanical stresses.
