7004 CE/P4ADGB 42 mm 20 mm 24 mm Frequently Asked Questions about 7004 CE/P4ADGB Super-precision Angular Contact Ball Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
The Open Type engineered for 7004 CE/P4ADGB 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.
To match diverse operational dynamics, CHG Bearing supplies 7004 CE/P4ADGB 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.
For international ocean and air freight, CHG Bearing packs 7004 CE/P4ADGB 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.
Engineered according to international ISO boundary plans, CHG Bearing supplies 7004 CE/P4ADGB with a precision bore diameter (d) of 20 mm, an outside diameter (D) of 42 mm, and a nominal ring width (B) of 24 mm. This configuration yields an effective cross-sectional wall thickness of 11.0 mm and an envelope ratio (D/d) of 2.1, delivering compact rigidity for OEM machinery housings.
