71816 ACD/P4DGB 100 mm 80 mm 20 mm Frequently Asked Questions about 71816 ACD/P4DGB Super-precision Angular Contact Ball Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Built for demanding industrial environments, the 71816 ACD/P4DGB Super-precision Angular Contact Ball Bearings by CHG Bearing boasts a dynamic load rating (Cr) of standard dynamic and a static load threshold (C0r) of standard static. The optimized internal raceway geometry balances stress distribution, mitigating edge loading even when operating under peak mechanical stresses.
Engineered according to international ISO boundary plans, CHG Bearing supplies 71816 ACD/P4DGB with a precision bore diameter (d) of 80 mm, an outside diameter (D) of 100 mm, and a nominal ring width (B) of 20 mm. This configuration yields an effective cross-sectional wall thickness of 10.0 mm and an envelope ratio (D/d) of 1.25, delivering compact rigidity for OEM machinery housings.
The CHG Bearing 71816 ACD/P4DGB 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.
To match diverse operational dynamics, CHG Bearing supplies 71816 ACD/P4DGB 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.
