S7213 CD/P4ADGC 120 mm 65 mm 46 mm Frequently Asked Questions about S7213 CD/P4ADGC 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 S7213 CD/P4ADGC 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 S7213 CD/P4ADGC 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.
When fitting S7213 CD/P4ADGC over a 65 mm shaft, CHG Bearing strictly recommends uniform induction heating (controlled between 90°C and 110°C) or precision hydraulic press sleeves. Under no circumstances should direct impact blows be struck against the rings or cage, as shock loads cause brinelling indents and premature spalling.
Engineered according to international ISO boundary plans, CHG Bearing supplies S7213 CD/P4ADGC with a precision bore diameter (d) of 65 mm, an outside diameter (D) of 120 mm, and a nominal ring width (B) of 46 mm. This configuration yields an effective cross-sectional wall thickness of 27.5 mm and an envelope ratio (D/d) of 1.85, delivering compact rigidity for OEM machinery housings.
