S71914 CD/P4ADBA 100 mm 70 mm 32 mm Frequently Asked Questions about S71914 CD/P4ADBA 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 S71914 CD/P4ADBA with a precision bore diameter (d) of 70 mm, an outside diameter (D) of 100 mm, and a nominal ring width (B) of 32 mm. This configuration yields an effective cross-sectional wall thickness of 15.0 mm and an envelope ratio (D/d) of 1.43, delivering compact rigidity for OEM machinery housings.
Quality starts with raw material selection: CHG Bearing crafts S71914 CD/P4ADBA 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.
As a primary manufacturer, CHG Bearing supports both trial batch evaluations and container-load supply for S71914 CD/P4ADBA. Standard catalog sizes are stocked for rapid 3–7 day dispatch, while high-volume OEM production runs typically dispatch within 30–45 days.
In its sealed configuration (Non-contact Seal), CHG Bearing pre-charges S71914 CD/P4ADBA 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.
