71907 CDGA/HCP4A 55 mm 35 mm 10 mm Frequently Asked Questions about 71907 CDGA/HCP4A Super-precision Angular Contact Ball Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Yes, 100% of 71907 CDGA/HCP4A 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.
Engineered according to international ISO boundary plans, CHG Bearing supplies 71907 CDGA/HCP4A with a precision bore diameter (d) of 35 mm, an outside diameter (D) of 55 mm, and a nominal ring width (B) of 10 mm. This configuration yields an effective cross-sectional wall thickness of 10.0 mm and an envelope ratio (D/d) of 1.57, delivering compact rigidity for OEM machinery housings.
Model 71907 CDGA/HCP4A 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 35 mm) and steep thermal gradients between inner and outer rings.
Absolutely. The CHG Bearing 71907 CDGA/HCP4A Super-precision Angular Contact Ball Bearings is a 1:1 direct interchange for renowned brands, matching part numbers: SKF 71907 CDGA/HCP4A, FAG 71907 CDGA/HCP4A, NSK 71907 CDGA/HCP4A. It shares identical envelope boundary dimensions, load capacities, and shaft fits, allowing instant drop-in replacement without retrofitting your machinery.
