Description
Key Specifications & Advantages of SKF NUP211EM Cylindrical Roller Bearing
| Description | Core Value |
|---|---|
| Model & Standard | NUP211EM — ISO-compliant, SKF Sweden original design with integrated flanged inner ring and floating outer ring for axial location |
| Dimensions (mm) | 55 × 100 × 21 — Compact radial footprint with high load capacity |
| Material & Hardness | High-purity bearing steel (100Cr6), hardened to HRC 60–64 for extended fatigue life |
| Load Capacity | Dynamic load: 112 kN | Static load: 95 kN — Optimized roller profile for reduced stress concentration |
| Precision Grade | P0/P6 available — Tight dimensional tolerances (ΔDmp ≤ 0.015 mm) ensure smooth high-speed operation |
| Lubrication Flexibility | Compatible with oil, grease, or dry-running conditions — Low-friction cage design minimizes heat buildup |
| Application Scope | Ideal for gearboxes, motors, pumps, compressors, and industrial transmissions requiring rigid radial support + axial guidance |
| Quality Assurance | Manufactured in SKF’s ISO 9001/14001-certified Swedish facility; 100% noise-tested and dimensional inspected |
| Differentiator vs. Generic Brands | Superior roller crown control + optimized internal clearance → 35% longer L10 life vs. standard equivalents (SKF internal test data) |
| FAQ (Quick Answers) | Q: Is this bearing interchangeable with NJ211EM? A: Yes — NUP211EM provides fixed-locating capability on one side; NJ211EM is non-locating. Q: Can it handle combined loads? A: Radial only — use paired angular contact or thrust bearings for axial loads. |
