71816 CD/P4 100 mm 80 mm 10 mm Frequently Asked Questions about 71816 CD/P4 Super-precision Angular Contact Ball Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Model 71816 CD/P4 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.
To match diverse operational dynamics, CHG Bearing supplies 71816 CD/P4 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.
Engineered according to international ISO boundary plans, CHG Bearing supplies 71816 CD/P4 with a precision bore diameter (d) of 80 mm, an outside diameter (D) of 100 mm, and a nominal ring width (B) of 10 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 Open Type engineered for 71816 CD/P4 by CHG Bearing utilizes precision non-contact metal shields or reinforced NBR/FKM contact lip seals. This barrier prevents particulate ingress, washdown fluids, and abrasive dust from reaching the raceways while eliminating grease leakage under centrifugal forces.
