Find key technical answers regarding dimensions, specifications, and replacement options for this model.
To match diverse operational dynamics, CHG Bearing supplies 709 CD/HCP4ADGA with multiple cage configurations: high-strength pressed steel ribbon cages for standard duty, solid machined brass cages (M/CA) for heavy vibration and shock loads, or lightweight glass-fiber reinforced polyamide cages (TN9/TVP) for high acceleration and ultra-low noise.
Quality starts with raw material selection: CHG Bearing crafts 709 CD/HCP4ADGA 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.
As a primary manufacturer, CHG Bearing supports both trial batch evaluations and container-load supply for 709 CD/HCP4ADGA. 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 709 CD/HCP4ADGA with a precision bore diameter (d) of 9 mm, an outside diameter (D) of 24 mm, and a nominal ring width (B) of 14 mm. This configuration yields an effective cross-sectional wall thickness of 7.5 mm and an envelope ratio (D/d) of 2.67, delivering compact rigidity for OEM machinery housings.
