Find key technical answers regarding dimensions, specifications, and replacement options for this model.
The CHG Bearing 71916 ACD/P4ADGB is rated for limiting speeds up to standard rated RPM under forced oil-mist or circulating oil lubrication regimes. When lubricated with factory-filled synthetic high-speed grease, safe continuous velocity is maintained at approximately 75% to 85% of the maximum nominal limit, preventing thermal runaway.
Engineered according to international ISO boundary plans, CHG Bearing supplies 71916 ACD/P4ADGB with a precision bore diameter (d) of 80 mm, an outside diameter (D) of 110 mm, and a nominal ring width (B) of 32 mm. This configuration yields an effective cross-sectional wall thickness of 15.0 mm and an envelope ratio (D/d) of 1.38, delivering compact rigidity for OEM machinery housings.
Yes, CHG Bearing works closely with industrial OEMs and brand distributors. We offer turnkey custom engineering for 71916 ACD/P4ADGB, including laser-etched customer logos, custom internal radial clearances, specialized grease formulations, and bespoke protective packaging.
Model 71916 ACD/P4ADGB 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 80 mm) and steep thermal gradients between inner and outer rings.
