Product Details
NTN N2320EM Series Cylindrical Roller Bearings – High-Precision Radial Solutions
| Description | Key Value |
|---|---|
| Core Application | Heavy-duty industrial gearboxes, motors, pumps & wind turbine gear systems |
| Dimension Standard | 100 × 215 × 73 mm (Bore × OD × Width) — ISO-compliant, direct SKF 22220/NU2320 drop-in replacement |
| Material & Heat Treatment | High-carbon chromium bearing steel (JIS G4805 SUJ2), vacuum-degassed, hardened to HRC 60–64 |
| Load Capacity | Dynamic Cr: 425 kN | Static C0r: 510 kN — 12% higher than generic equivalents |
| Precision & Vibration | P5 grade accuracy + Z2V2 low-noise specification — ideal for high-RPM applications ≥3000 rpm |
| Lubrication Flexibility | Pre-greased (Shell Alvania RL3) or oil-lubricated — sealed & relubricatable variants available |
| Design Advantage | Separable inner/outer rings (NJ/NF/NU/NUP configurations) — simplifies mounting & maintenance |
| Origin & Traceability | Manufactured in Japan under strict JIS B 1514-1 quality control; full lot traceability |
| Differentiator vs. Competitors | Lower surface roughness (Ra ≤ 0.2 μm), optimized roller profile — reduces edge stress by 28% |
| Warranty & Support | 36-month limited warranty; technical support & CAD models provided upon inquiry |
Engineered for reliability where failure is not an option: NTN’s N2320EM series delivers unmatched radial stiffness, thermal stability, and service life — especially under combined load & misalignment conditions. Unlike standard cylindrical rollers, its micro-ground raceways and crowned rollers minimize stress concentration and extend L10 life by up to 40%. Trusted by Tier-1 OEMs across Europe and Asia for mission-critical rotating equipment.
