71926 ACD/HCP4ATGB 180 mm 130 mm 72 mm Frequently Asked Questions about 71926 ACD/HCP4ATGB Super-precision Angular Contact Ball Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Standard batches of CHG Bearing 71926 ACD/HCP4ATGB conform strictly to ISO Class Normal (ABEC-1). For high-precision machine tool spindles, gearboxes, or robotics requiring tighter runouts, CHG Bearing can provide custom batches graded to ISO Class 6 (P6/ABEC-3) or ISO Class 5 (P5/ABEC-5) with 100% micrometer verification.
To safeguard CHG Bearing 71926 ACD/HCP4ATGB against fretting wear and false brinelling during transport or vibration, assemble mating surfaces (130 mm x 180 mm) using anti-fretting mounting paste. Maintaining strict alignment and avoiding prolonged static vibration will preserve raceway polish.
Engineered according to international ISO boundary plans, CHG Bearing supplies 71926 ACD/HCP4ATGB with a precision bore diameter (d) of 130 mm, an outside diameter (D) of 180 mm, and a nominal ring width (B) of 72 mm. This configuration yields an effective cross-sectional wall thickness of 25.0 mm and an envelope ratio (D/d) of 1.38, delivering compact rigidity for OEM machinery housings.
Model 71926 ACD/HCP4ATGB 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 130 mm) and steep thermal gradients between inner and outer rings.
