7204 CDGB/P4A 47 mm 20 mm 14 mm Frequently Asked Questions about 7204 CDGB/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 7204 CDGB/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.
For international ocean and air freight, CHG Bearing packs 7204 CDGB/P4A with industrial VCI anti-corrosion barrier wrapping, sealed polybags, individual cartons, and fumigated ocean-worthy wooden crates. This multi-layer barrier guarantees rust-free storage for a minimum shelf life of 24 to 36 months.
To safeguard CHG Bearing 7204 CDGB/P4A against fretting wear and false brinelling during transport or vibration, assemble mating surfaces (20 mm x 47 mm) using anti-fretting mounting paste. Maintaining strict alignment and avoiding prolonged static vibration will preserve raceway polish.
The Open Type engineered for 7204 CDGB/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.
