Product Details

NTN Japan-Made High-Precision Cylindrical Roller Bearings (NUP2344EM Series)

Description Key Value
Precision & Origin Japan-made, P0–P2 precision grades (ISO standard), superior dimensional stability vs. generic China-made
Load Capacity Radial-only design with high rigidity; 220×460×145 mm spec supports heavy industrial loads
Material & Hardness GCR15 bearing steel, hardened to HRC 60–64 for extended fatigue life
Separable Design NUP-type: inner ring + cage + rollers separable from outer ring — simplifies installation/maintenance
Lubrication Flexibility Compatible with both grease and oil — ideal for high-speed or high-temp environments
Vibration Control Z1V1–Z3V3 low-noise options available — meets strict OEM acoustic requirements
Application Scope Wind turbines, gearboxes, mining equipment, paper mills, CNC machine spindles
Quality Assurance 100% ISO 9001-certified production; each batch traceable via serial marking
Differentiator vs. Competitors NTN’s proprietary EM (Enhanced Machining) process ensures tighter raceway roundness & roller profile accuracy
FAQ – Technical Q: Can NUP2344EM handle axial loads? A: Yes — fixed on one side (NUP design includes flanged outer ring + loose inner ring with double flanges). Q: Is it interchangeable with SKF NU2344E? A: Dimensionally compatible, but NTN EM offers 18% higher L10 life per ISO 281.
