Suitable for OEM/ODM use with standard carton-pallet packaging.Key Specifications & Advantages of SKF NUP210EM Cylindrical Roller Bearing
| Description | Core Value |
|---|---|
| Model & Precision | NUP210EM, P0/P6/P5 precision grades — optimized for high-speed radial loads with axial location |
| Dimensions (mm) | 50×90×20 — compact yet robust; fits standard OEM housings & shafts |
| Material & Hardness | High-purity Swedish bearing steel (100Cr6), hardened to 60–63 HRC for extended fatigue life |
| Load Capacity | Radial-only + fixed axial positioning (NUP design); ideal for gearboxes & motors |
| Sealing & Lubrication | Open type — compatible with oil, grease, or dry-lube systems per application needs |
| Separability | Fully separable inner/outer rings — simplifies mounting, maintenance & replacement |
| Origin & Standards | Manufactured in Sweden under ISO 9001 & ISO/TS 16949 — traceable batch control |
| Differentiator vs. Generic Brands | Tighter dimensional tolerances (±0.005 mm), superior roller profile grinding, lower noise & vibration (≤28 dB) |
| Typical Applications | Industrial pumps, electric motors, wind turbine gearboxes, conveyor drives, machine tools |
| FAQ: Why choose NUP over NU/NJ? | NUP provides fixed axial location on both sides — no need for external thrust bearings or complex housing adjustments |
