71800 CDGB/P4 19 mm 10 mm 5 mm Frequently Asked Questions about 71800 CDGB/P4 Super-precision Angular Contact Ball Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Model 71800 CDGB/P4 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 10 mm) and steep thermal gradients between inner and outer rings.
Absolutely. The CHG Bearing 71800 CDGB/P4 Super-precision Angular Contact Ball Bearings is a 1:1 direct interchange for renowned brands, matching part numbers: SKF 71800 CDGB/P4, FAG 71800 CDGB/P4, NSK 71800 CDGB/P4. It shares identical envelope boundary dimensions, load capacities, and shaft fits, allowing instant drop-in replacement without retrofitting your machinery.
To safeguard CHG Bearing 71800 CDGB/P4 against fretting wear and false brinelling during transport or vibration, assemble mating surfaces (10 mm x 19 mm) using anti-fretting mounting paste. Maintaining strict alignment and avoiding prolonged static vibration will preserve raceway polish.
The CHG Bearing 71800 CDGB/P4 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.
