7224 CDGA/P4A 215 mm 120 mm 40 mm Frequently Asked Questions about 7224 CDGA/P4A Super-precision Angular Contact Ball Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Beyond standard alloy steel, CHG Bearing can customize the 7224 CDGA/P4A Super-precision Angular Contact Ball Bearings using AISI 440C stainless steel, black oxide coating, zinc-nickel plating, or hybrid ceramic (Si3N4) balls for applications involving chemical exposure, marine salt fog, or galvanic current hazards.
As a primary manufacturer, CHG Bearing supports both trial batch evaluations and container-load supply for 7224 CDGA/P4A. Standard catalog sizes are stocked for rapid 3–7 day dispatch, while high-volume OEM production runs typically dispatch within 30–45 days.
Engineered according to international ISO boundary plans, CHG Bearing supplies 7224 CDGA/P4A with a precision bore diameter (d) of 120 mm, an outside diameter (D) of 215 mm, and a nominal ring width (B) of 40 mm. This configuration yields an effective cross-sectional wall thickness of 47.5 mm and an envelope ratio (D/d) of 1.79, delivering compact rigidity for OEM machinery housings.
Quality starts with raw material selection: CHG Bearing crafts 7224 CDGA/P4A 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.
