Product Details
NTN Durable N2340em Series Cylindrical Roller Bearing – High-Performance Radial Solution
| Description | Core Value |
|---|---|
| Model Range | Nu2340em / NJ2340em / NF2340em / NUP2340em / N2340em — interchangeable high-precision variants |
| Bore & OD Size | 15–90 mm bore, 35–180 mm outer diameter; standard spec: 200×420×138 mm (robust load capacity) |
| Material & Hardness | High-carbon chromium bearing steel (GCr15), hardened to HRC 60–64 for extended fatigue life |
| Load & Alignment | Pure radial load design; non-aligning — ideal for rigid shaft applications requiring high-speed stability |
| Lubrication Flexibility | Compatible with premium grease or circulating oil — optimized for continuous industrial operation |
| Precision & Vibration | P0 to P2 accuracy grades; Z1V1–Z3V3 low-vibration options — meets ISO 492 & JIS B 1514 |
| Separable Design | Inner/outer rings separable — simplifies mounting, maintenance & OEM integration |
| Origin & Standards | Manufactured in Japan under strict NTN QM system; HS Code 8482500090 — fully compliant for global import |
| Key Applications | Wind turbines, gearboxes, mining conveyors, paper mills, and heavy-duty industrial drives |
| Why NTN vs. Generic? | Superior roller profile grinding, tighter raceway tolerances, and 30% longer L10 life vs. standard P0 bearings |
Engineered for reliability where downtime costs thousands — NTN’s N2340em series delivers unmatched radial stiffness, thermal stability, and contamination resistance. Backed by ISO 9001-certified production and 100% pre-shipment vibration testing. Need custom specs, bulk pricing, or technical support?
