Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Following standard ISO 281 fatigue calculation guidelines, the nominal rating life (L10) of CHG Bearing NU2338 correlates its dynamic capacity (standard dynamic) with equivalent dynamic loads. In controlled industrial settings with proper contamination-free filtration, field data confirms continuous operational longevity exceeding 20,000 to 50,000 service hours.
Quality starts with raw material selection: CHG Bearing crafts NU2338 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.
Engineered according to international ISO boundary plans, CHG Bearing supplies NU2338 with a precision bore diameter (d) of 190 mm, an outside diameter (D) of 400 mm, and a nominal ring width (B) of 132 mm. This configuration yields an effective cross-sectional wall thickness of 105.0 mm and an envelope ratio (D/d) of 2.11, delivering compact rigidity for OEM machinery housings.
Absolutely. The CHG Bearing NU2338 Single Row Cylindrical Roller Bearings is a 1:1 direct interchange for renowned brands, matching part numbers: SKF NU2338, FAG NU2338, NSK NU2338. It shares identical envelope boundary dimensions, load capacities, and shaft fits, allowing instant drop-in replacement without retrofitting your machinery.
