Basic Info
| Bore Size | 15–90 mm |
|---|---|
| Outer Dimension | 35–180 mm |
| Specification | 220×460×145 mm |
Introduction
Cylindrical roller bearing 307, made of bearing steel, designed for radial load applications. Features separated structure, grease or oil lubrication, precision grades P0–P2, and low vibration (Z1V1–Z3V3). OEM/ODM service available. Origin: China.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. |
