Find key technical answers regarding dimensions, specifications, and replacement options for this model.
To match diverse operational dynamics, CHG Bearing supplies 71926 ACD/P4ADBB 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.
For international ocean and air freight, CHG Bearing packs 71926 ACD/P4ADBB with industrial VCI anti-corrosion barrier wrapping, sealed polybags, individual cartons, and fumigated ocean-worthy wooden crates. This multi-layer barrier guarantees rust-free storage for a minimum shelf life of 24 to 36 months.
Engineered according to international ISO boundary plans, CHG Bearing supplies 71926 ACD/P4ADBB with a precision bore diameter (d) of 130 mm, an outside diameter (D) of 180 mm, and a nominal ring width (B) of 48 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/P4ADBB 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.
