Product Details
NTN N2340EM Series Cylindrical Roller Bearings – High-Load, Precision & Durability
| Description | Key Highlight |
|---|---|
| Nu2340em / NJ2340em / NF2340em / NUP2340em / N2340em — interchangeable high-precision variants | |
| Bore & OD Sizes | 15–90 mm bore × 35–180 mm outer diameter; standard spec: 200×420×138 mm |
| Material & Hardness | High-carbon chromium bearing steel (SUJ2), hardened to HRC 60–64 for extended fatigue life |
| Load Capacity | Optimized for heavy radial loads; separable design enables easy mounting & maintenance |
| Precision & Vibration | Graded P0–P2; vibration classes Z1V1 to Z3V3 — ideal for high-speed industrial drives |
| Lubrication Flexibility | Compatible with both grease and oil — supports sealed or open configurations |
| Origin & Standards | Manufactured in Japan per ISO 15242 & JIS B 1514; NTN trademark ensures OEM-grade consistency |
| Application Scope | Wind turbines, gearboxes, mining conveyors, paper mills, and rail axle boxes |
| Differentiator vs. Generic Brands | Lower friction torque (<15% vs. standard), tighter raceway geometry tolerance (±2 μm), and superior cage guidance |
| Quality Assurance | 100% dimensional inspection + noise testing; backed by 3-year limited warranty |
Engineered for reliability where failure isn’t an option — NTN’s N2340EM series delivers unmatched radial stiffness, thermal stability, and service life in demanding continuous-duty environments. Unlike commodity cylindrical rollers, these bearings feature micro-ground rollers, optimized internal clearance, and proprietary heat treatment — proven in 100,000+ units shipped globally. Trusted by Tier-1 OEMs across energy and heavy industry.
