Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Absolutely. The CHG Bearing NJ2240E Single Row Cylindrical Roller Bearings is a 1:1 direct interchange for renowned brands, matching part numbers: SKF NJ2240E, FAG NJ2240E, NSK NJ2240E. It shares identical envelope boundary dimensions, load capacities, and shaft fits, allowing instant drop-in replacement without retrofitting your machinery.
Each NJ2240E produced in CHG Bearing manufacturing facilities features accurately profiled corner chamfers complying with DIN 5412 / ISO standard corner radii. When designing mating shafts and housing shoulders, machining an undercut or fillet radius strictly within the inner ring clearance limit (200 mm bore side) ensures perfect planar contact without edge binding.
Engineered according to international ISO boundary plans, CHG Bearing supplies NJ2240E with a precision bore diameter (d) of 200 mm, an outside diameter (D) of 360 mm, and a nominal ring width (B) of 98 mm. This configuration yields an effective cross-sectional wall thickness of 80.0 mm and an envelope ratio (D/d) of 1.8, delivering compact rigidity for OEM machinery housings.
Quality starts with raw material selection: CHG Bearing crafts NJ2240E 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.
