Introduction
Cylindrical roller bearing, single-row, open type, made of bearing steel. Designed for radial load applications with high precision (P0–P2), suitable for OEM/ODM use. Lubrication options: oil, grease or dry. Outer dimensions range 35–400 mm. Origin: China. HS Code: 8482500090.Why Choose Our High-Precision Cylindrical Roller Bearings?
| Description | Key Value |
|---|---|
| Brand Compatibility | Interchangeable with SKF, Timken, NTN, NSK, KOYO, NACHI — ideal for global OEM replacements |
| Precision Grades | P0 to P2 (ABEC-1 to ABEC-9) — ultra-tight tolerances for high-speed & low-vibration applications |
| Load Capacity | Optimized radial load support up to 400mm OD — superior rigidity vs. standard roller bearings |
| Material & Hardness | GCR15 bearing steel, 60–64 HRC — fatigue-resistant, long service life |
| Design Type | Separable NJ/NU series — easy mounting, axial location flexibility (NJ fixed one side, NU floating) |
| Sealing & Lubrication | Open design — compatible with oil, grease, or dry-lube systems per your operational needs |
| Applications | Wind turbines, gearboxes, machine tools, compressors, and heavy-duty industrial drives |
| Quality Assurance | 100% dimensional inspection + noise/vibration testing; ISO 9001 & IATF 16949 certified production |
| Differentiator | EM cages (polyamide-reinforced) — higher speed capability & quieter operation than stamped steel |
| FAQ: Can these replace SKF NJ419EMA? | Yes — identical internal geometry, load ratings, and interchange dimensions per ISO 10322 |
