7011 ACE/HCP4ADGB 90 mm 55 mm 36 mm Frequently Asked Questions about 7011 ACE/HCP4ADGB 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 7011 ACE/HCP4ADGB with a precision bore diameter (d) of 55 mm, an outside diameter (D) of 90 mm, and a nominal ring width (B) of 36 mm. This configuration yields an effective cross-sectional wall thickness of 17.5 mm and an envelope ratio (D/d) of 1.64, delivering compact rigidity for OEM machinery housings.
The CHG Bearing 7011 ACE/HCP4ADGB is rated for limiting speeds up to standard rated RPM under forced oil-mist or circulating oil lubrication regimes. When lubricated with factory-filled synthetic high-speed grease, safe continuous velocity is maintained at approximately 75% to 85% of the maximum nominal limit, preventing thermal runaway.
Absolutely. The CHG Bearing 7011 ACE/HCP4ADGB Super-precision Angular Contact Ball Bearings is a 1:1 direct interchange for renowned brands, matching part numbers: SKF 7011 ACE/HCP4ADGB, FAG 7011 ACE/HCP4ADGB, NSK 7011 ACE/HCP4ADGB. It shares identical envelope boundary dimensions, load capacities, and shaft fits, allowing instant drop-in replacement without retrofitting your machinery.
Model 7011 ACE/HCP4ADGB 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 55 mm) and steep thermal gradients between inner and outer rings.
