S7208 CDGC/P4A 80 mm 40 mm 18 mm Frequently Asked Questions about S7208 CDGC/P4A 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 S7208 CDGC/P4A 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.
Model S7208 CDGC/P4A 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 40 mm) and steep thermal gradients between inner and outer rings.
The Non-contact Seal engineered for S7208 CDGC/P4A 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.
Engineered according to international ISO boundary plans, CHG Bearing supplies S7208 CDGC/P4A with a precision bore diameter (d) of 40 mm, an outside diameter (D) of 80 mm, and a nominal ring width (B) of 18 mm. This configuration yields an effective cross-sectional wall thickness of 20.0 mm and an envelope ratio (D/d) of 2.0, delivering compact rigidity for OEM machinery housings.
