Product Details
High Precision Cylindrical Roller Bearing N220EM Series
| Description | Key Selling Points |
|---|---|
| Model Range | N220EM, NJ220EM, NF220EM, NU220EM, NUP220EM — interchangeable high-precision variants for diverse mounting needs |
| Dimension Range | Outer diameter: 35–400 mm; standard size: 100×180×34 mm — ideal for industrial gearboxes & motors |
| Material & Hardness | High-carbon chromium bearing steel (GCr15), hardened to HRC 60–64 — ensures extended fatigue life |
| Precision Grade | P0 to P2 (ABEC-1 to ABEC-9 equivalent) — ultra-tight tolerances for high-speed, low-vibration operation |
| Load Capacity | Optimized radial load handling with rigid cylindrical rollers — up to 30% higher dynamic load vs. generic brands |
| Design Features | Separated, open-type construction — enables easy installation, maintenance, and axial displacement compensation |
| Lubrication Flexibility | Compatible with oil, grease, or dry-film lubricants — adaptable to harsh or high-temp environments |
| Quality Assurance | 100% ISO 9001 & IATF 16949 certified production; 100,000 units/month capacity; traceable batch testing |
| SKF-Compatible Performance | Meets SKF N220 series dimensional & performance specs — seamless OEM replacement without redesign |
| FAQ Highlights | Q: Are these bearings pre-lubricated? A: No — supplied dry for customer-specific lubricant selection. Q: Can NUP220EM replace SKF NUP220? A: Yes — identical bore/OD/width + enhanced cage rigidity. Q: What’s the max operating temp? A: 120°C continuous (with proper lubrication). |
