Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Quality starts with raw material selection: CHG Bearing crafts 7011 CD/P4ADBA 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.
Engineered according to international ISO boundary plans, CHG Bearing supplies 7011 CD/P4ADBA with a precision bore diameter (d) of 55 mm, an outside diameter (D) of 90 mm, and a nominal ring width (B) of 36 mm. This configuration yields an effective cross-sectional wall thickness of 17.5 mm and an envelope ratio (D/d) of 1.64, delivering compact rigidity for OEM machinery housings.
Standard batches of CHG Bearing 7011 CD/P4ADBA 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.
To match diverse operational dynamics, CHG Bearing supplies 7011 CD/P4ADBA 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.
