7204 ACD/P4ADGA 47 mm 20 mm 28 mm Frequently Asked Questions about 7204 ACD/P4ADGA Super-precision Angular Contact Ball Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Built for demanding industrial environments, the 7204 ACD/P4ADGA 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.
To safeguard CHG Bearing 7204 ACD/P4ADGA against fretting wear and false brinelling during transport or vibration, assemble mating surfaces (20 mm x 47 mm) using anti-fretting mounting paste. Maintaining strict alignment and avoiding prolonged static vibration will preserve raceway polish.
Model 7204 ACD/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 20 mm) and steep thermal gradients between inner and outer rings.
Absolutely. The CHG Bearing 7204 ACD/P4ADGA Super-precision Angular Contact Ball Bearings is a 1:1 direct interchange for renowned brands, matching part numbers: SKF 7204 ACD/P4ADGA, FAG 7204 ACD/P4ADGA, NSK 7204 ACD/P4ADGA. It shares identical envelope boundary dimensions, load capacities, and shaft fits, allowing instant drop-in replacement without retrofitting your machinery.
