Product Details
Key Specifications & Why NU412EM Stands Out
| Description | Core Value |
|---|---|
| Model: NU412EM (Cylindrical Roller, Non-locating, Open Type) | Precision radial support with high-speed stability & easy mounting |
| Dimensions: 60×130×31 mm (ID×OD×W) | Industry-standard size — direct replacement for SKF NU412, NSK NU412, Koyo NU412 |
| Material: High-Carbon Chromium Bearing Steel (GCR15 / SAE 52100) | Superior hardness (HRC 60–64), fatigue resistance & dimensional stability |
| Precision Grade: P0 / P6 / P5 Available | P6 grade meets SKF Explorer-level accuracy — ideal for CNC spindles & gearboxes |
| Load Capacity: Dynamic Cr = 285 kN | Static C0r = 335 kN | 22% higher static load vs. generic equivalents — extended service life under shock loads |
| Lubrication: Oil, Grease or Solid Film Compatible | Optimized internal geometry reduces friction — lower operating temp & energy use |
| Applications: Industrial Gearboxes, Wind Turbine Gearboxes, Paper Mills, Steel Rolling Mills | Proven in >500 OEM installations across heavy industry & renewable energy |
| Quality Assurance: ISO 9001, IATF 16949, 100% Dimensional & Noise Testing | Zero batch rejection in 2025 audits — traceable lot documentation included |
| Differentiator: Optimized roller profile + crowned ends | Eliminates edge stress — 3.2× longer L10 life vs. non-crowned competitors |
| FAQ: Can it replace SKF NU412? Yes — identical ABEC/ISO tolerances, interchange dimensions & load ratings. | Yes. Full compatibility confirmed per SKF catalog 2024, page NU-400 series. |
