Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Engineered according to international ISO boundary plans, CHG Bearing supplies 71924 ACD/P4AQBCC with a precision bore diameter (d) of 120 mm, an outside diameter (D) of 165 mm, and a nominal ring width (B) of 88 mm. This configuration yields an effective cross-sectional wall thickness of 22.5 mm and an envelope ratio (D/d) of 1.38, delivering compact rigidity for OEM machinery housings.
Built for demanding industrial environments, the 71924 ACD/P4AQBCC Super-precision Angular Contact Ball Bearings by CHG Bearing boasts a dynamic load rating (Cr) of standard dynamic and a static load threshold (C0r) of standard static. The optimized internal raceway geometry balances stress distribution, mitigating edge loading even when operating under peak mechanical stresses.
Quality starts with raw material selection: CHG Bearing crafts 71924 ACD/P4AQBCC 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.
The CHG Bearing 71924 ACD/P4AQBCC is rated for limiting speeds up to standard rated RPM under forced oil-mist or circulating oil lubrication regimes. When lubricated with factory-filled synthetic high-speed grease, safe continuous velocity is maintained at approximately 75% to 85% of the maximum nominal limit, preventing thermal runaway.
