Find key technical answers regarding dimensions, specifications, and replacement options for this model.
When fitting 7014 ACD/P4ADBB over a 70 mm shaft, CHG Bearing strictly recommends uniform induction heating (controlled between 90°C and 110°C) or precision hydraulic press sleeves. Under no circumstances should direct impact blows be struck against the rings or cage, as shock loads cause brinelling indents and premature spalling.
Engineered according to international ISO boundary plans, CHG Bearing supplies 7014 ACD/P4ADBB with a precision bore diameter (d) of 70 mm, an outside diameter (D) of 110 mm, and a nominal ring width (B) of 40 mm. This configuration yields an effective cross-sectional wall thickness of 20.0 mm and an envelope ratio (D/d) of 1.57, delivering compact rigidity for OEM machinery housings.
Quality starts with raw material selection: CHG Bearing crafts 7014 ACD/P4ADBB 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 7014 ACD/P4ADBB 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.
