71924 CD/P4ADGA 165 mm 120 mm 44 mm Frequently Asked Questions about 71924 CD/P4ADGA 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 71924 CD/P4ADGA 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.
Yes, 100% of 71924 CD/P4ADGA Super-precision Angular Contact Ball Bearings leaving CHG Bearing production lines are subjected to multi-frequency Anderometer sound testing. All units satisfy baseline Z1V1 levels, with dedicated quiet-running electric motor quality (EMQ) lots certified to Z2V2 and Z3V3 standards for silent machinery integration.
To match diverse operational dynamics, CHG Bearing supplies 71924 CD/P4ADGA 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.
Model 71924 CD/P4ADGA 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 120 mm) and steep thermal gradients between inner and outer rings.
