Key Specifications & Advantages of Precision Cylindrical Roller Bearing NUP218EM
| Description | Core Value |
|---|---|
| Model: NUP218EM (Interchangeable with N218EM, NJ218EM, NF218EM, NU218EM) | Universal fit — seamless replacement for major OEM & competitor designs |
| Dimensions: 90 × 160 × 30 mm (ID × OD × W) | Optimized for high-speed, medium-load radial applications |
| Material: Premium GCR15 bearing steel (equivalent to SKF 2310/22208) | Superior hardness & fatigue resistance; extends service life by 30%+ vs. standard grade |
| Precision Grade: P0–P2 (ISO standard) | P2 option available — meets SKF Explorer-level accuracy for critical machinery |
| Load Type: Radial-only, non-aligning, separated design | Enables precise axial location + easy mounting/dismounting — ideal for gearboxes & pumps |
| Lubrication: Compatible with oil, grease, or dry-film lubricants | Reduces maintenance downtime; validated for SKF LGMT 2 & LGHP 2 greases |
| Seal Type: Open (no seals) | Maximizes heat dissipation & rotational efficiency — preferred in precision grinding spindles |
| Origin & Quality: Made in China under ISO 9001 & IATF 16949 | Third-party audited — full traceability & 100% dimensional inspection per batch |
| Application Examples: CNC grinders, textile machines, wind turbine gearboxes, compressors | Proven in >12 industrial sectors — backed by 5-year field reliability data |
| FAQ: Is this compatible with SKF NUP218E? Yes — identical internal geometry, load ratings & mounting dimensions per ISO 104. | No re-engineering needed — drop-in upgrade for existing SKF systems |
