S7204 CDGC/P4A 47 mm 20 mm 14 mm Frequently Asked Questions about S7204 CDGC/P4A Super-precision Angular Contact Ball Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Quality starts with raw material selection: CHG Bearing crafts S7204 CDGC/P4A 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.
As standard production, CHG Bearing subjects S7204 CDGC/P4A to precision bainite or martensite quenching, offering dimensional stability up to 120°C (248°F). For high-heat processing equipment, CHG Bearing also supplies custom S0 (150°C), S1 (200°C), or S2 (250°C) stabilization heat treatments upon request to prevent residual austenite transformation.
Engineered according to international ISO boundary plans, CHG Bearing supplies S7204 CDGC/P4A with a precision bore diameter (d) of 20 mm, an outside diameter (D) of 47 mm, and a nominal ring width (B) of 14 mm. This configuration yields an effective cross-sectional wall thickness of 13.5 mm and an envelope ratio (D/d) of 2.35, delivering compact rigidity for OEM machinery housings.
Yes, CHG Bearing works closely with industrial OEMs and brand distributors. We offer turnkey custom engineering for S7204 CDGC/P4A, including laser-etched customer logos, custom internal radial clearances, specialized grease formulations, and bespoke protective packaging.
