S7216 CD/P4ADBB 140 mm 80 mm 52 mm Frequently Asked Questions about S7216 CD/P4ADBB Super-precision Angular Contact Ball Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
The CHG Bearing S7216 CD/P4ADBB 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.
Quality starts with raw material selection: CHG Bearing crafts S7216 CD/P4ADBB inner and outer rings from high-purity High-Quality Chrome Steel (GCr15/100Cr6). Our raw billets undergo vacuum degassing and secondary ESR (electroslag remelting) processes to drastically eliminate non-metallic sulfide and oxide inclusions, elevating subsurface contact fatigue resistance.
Standard batches of CHG Bearing S7216 CD/P4ADBB conform strictly to ISO Class Normal (ABEC-1). For high-precision machine tool spindles, gearboxes, or robotics requiring tighter runouts, CHG Bearing can provide custom batches graded to ISO Class 6 (P6/ABEC-3) or ISO Class 5 (P5/ABEC-5) with 100% micrometer verification.
Engineered according to international ISO boundary plans, CHG Bearing supplies S7216 CD/P4ADBB with a precision bore diameter (d) of 80 mm, an outside diameter (D) of 140 mm, and a nominal ring width (B) of 52 mm. This configuration yields an effective cross-sectional wall thickness of 30.0 mm and an envelope ratio (D/d) of 1.75, delivering compact rigidity for OEM machinery housings.
