S7006 CD/HCP4ADFB 55 mm 30 mm 26 mm Frequently Asked Questions about S7006 CD/HCP4ADFB Super-precision Angular Contact Ball Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Model S7006 CD/HCP4ADFB 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 30 mm) and steep thermal gradients between inner and outer rings.
The CHG Bearing S7006 CD/HCP4ADFB 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 S7006 CD/HCP4ADFB Super-precision Angular Contact Ball Bearings is a 1:1 direct interchange for renowned brands, matching part numbers: SKF S7006 CD/HCP4ADFB, FAG S7006 CD/HCP4ADFB, NSK S7006 CD/HCP4ADFB. It shares identical envelope boundary dimensions, load capacities, and shaft fits, allowing instant drop-in replacement without retrofitting your machinery.
In its sealed configuration (Non-contact Seal), CHG Bearing pre-charges S7006 CD/HCP4ADFB with premium wide-temperature lithium-complex or polyurea grease, calibrated to a 30%–35% cavity volume ratio. For open-type variants, synthetic PAO or refined mineral lubricating oils with appropriate EP (Extreme Pressure) additives should be circulated.
