Product Details
NTN Japan-Made High-Precision Cylindrical Roller Bearings (NUP2330EM Series)
| Description | Key Value |
|---|---|
| Precision & Origin | Made in Japan; P0–P2 precision grades (ISO/JIS compliant) |
| Load Capacity | High radial load, optimized cage design for dynamic stability |
| Material | High-carbon chromium bearing steel (SUJ2 equivalent), vacuum-melted |
| Dimensions (mm) | Bore: 150 × Outer: 320 × Width: 108 — ideal for heavy-duty industrial shafts |
| Lubrication Flexibility | Compatible with both grease and oil — pre-lubricated options available |
| Vibration Control | Z1V1–Z3V3 low-noise grades certified for precision machinery |
| Separable Design | NUP series allows easy mounting/dismounting — saves maintenance time |
| Application Scope | Wind turbines, gearboxes, mining equipment, paper mills, steel rolling mills |
| Quality Assurance | 100% dimensional inspection + noise/vibration testing per ISO 15242 |
| SKF-Compatible Advantage | Interchangeable with SKF NU/NUP2330 series — no redesign needed |
Engineered for reliability where failure isn’t an option — NTN’s NUP2330EM delivers unmatched Japanese precision, thermal stability, and fatigue resistance. Unlike generic Chinese alternatives, every batch undergoes strict JIS B 1514-1 verification and is traceable to the Nagano plant. Ideal for OEMs seeking drop-in replacement bearings without compromising on life or noise performance.
FAQ: Q: Is this bearing suitable for high-speed applications? A: Yes — up to 3,200 rpm (with proper lubrication and cooling). Q: Can it handle axial loads? A: NUP design supports bidirectional axial loads on the inner ring. Q: Do you offer custom cages or seals? A: Yes — brass, polyamide, or stainless steel cages on request.
