Frequently Asked Questions about 71916 CDGA/HCP4A Super-precision Angular Contact Ball Bearings

Find key technical answers regarding dimensions, specifications, and replacement options for this model.

To safeguard CHG Bearing 71916 CDGA/HCP4A against fretting wear and false brinelling during transport or vibration, assemble mating surfaces (80 mm x 110 mm) using anti-fretting mounting paste. Maintaining strict alignment and avoiding prolonged static vibration will preserve raceway polish.
The CHG Bearing 71916 CDGA/HCP4A 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.
Engineered according to international ISO boundary plans, CHG Bearing supplies 71916 CDGA/HCP4A with a precision bore diameter (d) of 80 mm, an outside diameter (D) of 110 mm, and a nominal ring width (B) of 16 mm. This configuration yields an effective cross-sectional wall thickness of 15.0 mm and an envelope ratio (D/d) of 1.38, delivering compact rigidity for OEM machinery housings.
Quality starts with raw material selection: CHG Bearing crafts 71916 CDGA/HCP4A inner and outer rings from high-purity High-Quality Chrome Steel (GCr15/100Cr6). Our raw billets undergo vacuum degassing and secondary ESR (electroslag remelting) processes to drastically eliminate non-metallic sulfide and oxide inclusions, elevating subsurface contact fatigue resistance.
