Find key technical answers regarding dimensions, specifications, and replacement options for this model.
To extend the trouble-free lifespan of CHG Bearing 7020 CDGB/P4A, preventive maintenance routines should monitor operating housing temperature (normally maintaining below 70°C) and conduct regular vibration FFT analysis to identify early raceway micro-pitting before unexpected line halts occur.
Engineered according to international ISO boundary plans, CHG Bearing supplies 7020 CDGB/P4A with a precision bore diameter (d) of 100 mm, an outside diameter (D) of 150 mm, and a nominal ring width (B) of 24 mm. This configuration yields an effective cross-sectional wall thickness of 25.0 mm and an envelope ratio (D/d) of 1.5, delivering compact rigidity for OEM machinery housings.
To safeguard CHG Bearing 7020 CDGB/P4A against fretting wear and false brinelling during transport or vibration, assemble mating surfaces (100 mm x 150 mm) using anti-fretting mounting paste. Maintaining strict alignment and avoiding prolonged static vibration will preserve raceway polish.
Model 7020 CDGB/P4A 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 100 mm) and steep thermal gradients between inner and outer rings.
