71948 CDGA/P4A 320 mm 240 mm 38 mm Frequently Asked Questions about 71948 CDGA/P4A Super-precision Angular Contact Ball Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Beyond standard alloy steel, CHG Bearing can customize the 71948 CDGA/P4A Super-precision Angular Contact Ball Bearings using AISI 440C stainless steel, black oxide coating, zinc-nickel plating, or hybrid ceramic (Si3N4) balls for applications involving chemical exposure, marine salt fog, or galvanic current hazards.
Model 71948 CDGA/P4A 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 240 mm) and steep thermal gradients between inner and outer rings.
Engineered according to international ISO boundary plans, CHG Bearing supplies 71948 CDGA/P4A with a precision bore diameter (d) of 240 mm, an outside diameter (D) of 320 mm, and a nominal ring width (B) of 38 mm. This configuration yields an effective cross-sectional wall thickness of 40.0 mm and an envelope ratio (D/d) of 1.33, delivering compact rigidity for OEM machinery housings.
Absolutely. The CHG Bearing 71948 CDGA/P4A Super-precision Angular Contact Ball Bearings is a 1:1 direct interchange for renowned brands, matching part numbers: SKF 71948 CDGA/P4A, FAG 71948 CDGA/P4A, NSK 71948 CDGA/P4A.
