SKF N211EM Cylindrical Roller Bearing – High Load, Precision, Low Friction
Basic Info
| Inner Diameter | 55 mm |
|---|---|
| Outer Diameter | 100 mm |
| Width | 21 mm |
Introduction
NUP211EM is a single-row cylindrical roller bearing made of bearing steel, designed for radial loads. It features an open seal type, separated structure, and precision ratings from P0 to P2. Suitable for OEM/ODM applications with standard oil/grease lubrication.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 GCr15 bearing steel, hardened to 60–63 HRC for extended fatigue life |
| Load Capacity | Dynamic Load: 112 kN / Static Load: 95 kN — Optimized for heavy radial + limited axial loads |
| Precision Grade | P0 (ABEC-1) standard; optional P6/P5 for high-speed or precision applications |
| Lubrication & Sealing | Open type — compatible with oil, grease, or dry-lube systems; easy relubrication via grooved outer ring |
| Application Scope | Industrial gearboxes, motors, pumps, compressors, wind turbine yaw systems, and railway axle boxes |
| Quality Assurance | 100% SKF Sweden traceability; ISO 9001 & IATF 16949 certified production; batch-tested for vibration & noise |
| Differentiator vs. Generic Brands | Superior roller profile correction (logarithmic), optimized internal clearance, and tighter raceway surface roughness (<0.2 μm Ra) |
| FAQ (Technical) | Q: Can it replace NU211EM? A: Yes — NUP211EM adds fixed axial positioning on one side. Q: Max speed? A: 5,600 rpm (grease), 7,200 rpm (oil). Q: RoHS compliant? Yes. |
