Product Details
SKF NU2203EM/NU2204EM Cylindrical Roller Bearings – Precision, Reliability & Performance
| Description | Key Highlight |
|---|---|
| High-precision cylindrical roller bearing (P0–P2 grades) | Ultra-tight tolerances for minimal vibration & extended service life |
| Separable design (NUP series) | Easy mounting/dismounting; ideal for fixed-locating applications |
| Bearing steel (GCr15) with optimized heat treatment | Superior hardness (HRC 60–64), fatigue resistance & dimensional stability |
| Open type, oil/grease/dry lubrication compatible | Flexible maintenance & integration into diverse industrial systems |
| Radial load capacity up to 125 kN (NU2204EM) | Engineered for heavy-duty, high-speed machinery |
| Non-aligning, rigid structure | Ensures precise shaft positioning under dynamic loads |
| 20×47×18 mm (NU2203EM) / 20×47×18 mm (spec listed; confirm actual NU2204EM: 20×47×18 mm is inconsistent — typical NU2204EM = 20×47×18 mm is correct per SKF catalog) | Compact footprint without compromising rigidity or load rating |
| Manufactured in Sweden, ISO 9001 & IATF 16949 certified | Traceable quality, full compliance with global OEM standards |
| Used in gearboxes, motors, pumps, compressors & wind turbines | Proven reliability in demanding continuous-operation environments |
| Compared to generic brands: 35% longer L10 life, lower noise (≤28 dB), tighter radial runout (≤3 μm) | Real ROI through reduced downtime & maintenance costs |
Frequently Asked Questions:
• Are these genuine SKF bearings? Yes — direct-sourced, batch-traceable, with official SKF documentation.
• Can they replace older NU2203/NU2204 models? Yes — EM suffix denotes enhanced internal geometry and cage design.
• What’s the max operating temperature? Up to 120°C continuous (with proper lubrication).
• Do you support custom packaging or labeling? Yes — OEM/ODM services available upon request.
