71916 FEGA/HCP4AL 110 mm 80 mm 16 mm Frequently Asked Questions about 71916 FEGA/HCP4AL Super-precision Angular Contact Ball Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Yes, 100% of 71916 FEGA/HCP4AL Super-precision Angular Contact Ball Bearings leaving CHG Bearing production lines are subjected to multi-frequency Anderometer sound testing. All units satisfy baseline Z1V1 levels, with dedicated quiet-running electric motor quality (EMQ) lots certified to Z2V2 and Z3V3 standards for silent machinery integration.
Engineered according to international ISO boundary plans, CHG Bearing supplies 71916 FEGA/HCP4AL 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 FEGA/HCP4AL 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.
In its sealed configuration (Open Type), CHG Bearing pre-charges 71916 FEGA/HCP4AL 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.
