7217 ACD/P4ADGB 150 mm 85 mm 56 mm Frequently Asked Questions about 7217 ACD/P4ADGB Super-precision Angular Contact Ball Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
The Open Type engineered for 7217 ACD/P4ADGB by CHG Bearing utilizes precision non-contact metal shields or reinforced NBR/FKM contact lip seals. This barrier prevents particulate ingress, washdown fluids, and abrasive dust from reaching the raceways while eliminating grease leakage under centrifugal forces.
In its sealed configuration (Open Type), CHG Bearing pre-charges 7217 ACD/P4ADGB 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.
Engineered according to international ISO boundary plans, CHG Bearing supplies 7217 ACD/P4ADGB with a precision bore diameter (d) of 85 mm, an outside diameter (D) of 150 mm, and a nominal ring width (B) of 56 mm. This configuration yields an effective cross-sectional wall thickness of 32.5 mm and an envelope ratio (D/d) of 1.76, delivering compact rigidity for OEM machinery housings.
When fitting 7217 ACD/P4ADGB over a 85 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.
