Frequently Asked Questions about 7009 FE/HCP4AH1DGA Super-precision Angular Contact Ball Bearings

Find key technical answers regarding dimensions, specifications, and replacement options for this model.

Engineered according to international ISO boundary plans, CHG Bearing supplies 7009 FE/HCP4AH1DGA with a precision bore diameter (d) of 45 mm, an outside diameter (D) of 75 mm, and a nominal ring width (B) of 32 mm. This configuration yields an effective cross-sectional wall thickness of 15.0 mm and an envelope ratio (D/d) of 1.67, delivering compact rigidity for OEM machinery housings.
Quality starts with raw material selection: CHG Bearing crafts 7009 FE/HCP4AH1DGA 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.
Model 7009 FE/HCP4AH1DGA is manufactured by CHG Bearing in standard Normal clearance (CN) for ambient temperature transmission, and C3 or C4 clearance for heavy duty applications. C3 clearance compensates for radial shrinkage caused by tight shaft press-fits (bore 45 mm) and steep thermal gradients between inner and outer rings.
Standard batches of CHG Bearing 7009 FE/HCP4AH1DGA conform strictly to ISO Class Normal (ABEC-1). For high-precision machine tool spindles, gearboxes, or robotics requiring tighter runouts, CHG Bearing can provide custom batches graded to ISO Class 6 (P6/ABEC-3) or ISO Class 5 (P5/ABEC-5) with 100% micrometer verification.
