Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Engineered according to international ISO boundary plans, CHG Bearing supplies 708 ACDGA/HCP4A with a precision bore diameter (d) of 8 mm, an outside diameter (D) of 22 mm, and a nominal ring width (B) of 7 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.
As a primary manufacturer, CHG Bearing supports both trial batch evaluations and container-load supply for 708 ACDGA/HCP4A. Standard catalog sizes are stocked for rapid 3–7 day dispatch, while high-volume OEM production runs typically dispatch within 30–45 days.
Sourcing 708 ACDGA/HCP4A directly from CHG Bearing eliminates intermediate brokerage markups while granting you factory-direct engineering backup, rigorous ISO-certified quality assurance, competitive volume wholesale pricing, and dependable supply chain stability for Super-precision Angular Contact Ball Bearings.
Quality starts with raw material selection: CHG Bearing crafts 708 ACDGA/HCP4A 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.
