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/P4ADBD with a precision bore diameter (d) of 120 mm, an outside diameter (D) of 165 mm, and a nominal ring width (B) of 44 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.
Every production batch of CHG Bearing 71924 ACD/P4ADBD Super-precision Angular Contact Ball Bearings comes with complete traceability. Upon shipment, CHG Bearing can provide EN 10204 3.1 Material Test Reports (MTR), Certificates of Conformity (CoC), spectral chemical composition analysis, and dimensional inspection sheets.
The Open Type engineered for 71924 ACD/P4ADBD by CHG Bearing utilizes precision non-contact metal shields or reinforced NBR/FKM contact lip seals. This barrier prevents particulate ingress, washdown fluids, and abrasive dust from reaching the raceways while eliminating grease leakage under centrifugal forces.
To match diverse operational dynamics, CHG Bearing supplies 71924 ACD/P4ADBD 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.
