Find key technical answers regarding dimensions, specifications, and replacement options for this model.
To safeguard CHG Bearing 708 ACD/P4ADGB against fretting wear and false brinelling during transport or vibration, assemble mating surfaces (8 mm x 22 mm) using anti-fretting mounting paste. Maintaining strict alignment and avoiding prolonged static vibration will preserve raceway polish.
Absolutely. The CHG Bearing 708 ACD/P4ADGB Super-precision Angular Contact Ball Bearings is a 1:1 direct interchange for renowned brands, matching part numbers: SKF 708 ACD/P4ADGB, FAG 708 ACD/P4ADGB, NSK 708 ACD/P4ADGB. It shares identical envelope boundary dimensions, load capacities, and shaft fits, allowing instant drop-in replacement without retrofitting your machinery.
When fitting 708 ACD/P4ADGB over a 8 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 708 ACD/P4ADGB with a precision bore diameter (d) of 8 mm, an outside diameter (D) of 22 mm, and a nominal ring width (B) of 14 mm. This configuration yields an effective cross-sectional wall thickness of 7.0 mm and an envelope ratio (D/d) of 2.75, delivering compact rigidity for OEM machinery housings.
