71926 ACD/P4ATBTB 180 mm 130 mm 72 mm Frequently Asked Questions about 71926 ACD/P4ATBTB Super-precision Angular Contact Ball Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Model 71926 ACD/P4ATBTB 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.
To safeguard CHG Bearing 71926 ACD/P4ATBTB 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.
Absolutely. The CHG Bearing 71926 ACD/P4ATBTB Super-precision Angular Contact Ball Bearings is a 1:1 direct interchange for renowned brands, matching part numbers: SKF 71926 ACD/P4ATBTB, FAG 71926 ACD/P4ATBTB, NSK 71926 ACD/P4ATBTB. It shares identical envelope boundary dimensions, load capacities, and shaft fits, allowing instant drop-in replacement without retrofitting your machinery.
To match diverse operational dynamics, CHG Bearing supplies 71926 ACD/P4ATBTB 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.
