Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Standard batches of CHG Bearing S7004 ACDGA/P4A 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 S7004 ACDGA/P4A with a precision bore diameter (d) of 20 mm, an outside diameter (D) of 42 mm, and a nominal ring width (B) of 12 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.
Sourcing S7004 ACDGA/P4A directly from CHG Bearing eliminates intermediate brokerage markups while granting you factory-direct engineering backup, rigorous ISO-certified quality assurance, competitive volume wholesale pricing, and dependable supply chain stability for Super-precision Angular Contact Ball Bearings.
To match diverse operational dynamics, CHG Bearing supplies S7004 ACDGA/P4A 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.
