Key Specifications & Advantages of NTN N320EM Cylindrical Roller Bearing
| Description | Core Value |
|---|---|
| Model Range: N320EM / NJ320EM / NF320EM / NU320EM / NUP320EM | Interchangeable high-precision variants for radial load flexibility |
| Bore × OD × Width: 100 × 215 × 47 mm (per spec) | Optimized for heavy-duty industrial shafts & housings |
| Material: Premium GCR15 Bearing Steel | Enhanced hardness (HRC 60–64), fatigue resistance & longevity |
| Precision Grades: P0, P6, P5, P4, P2 | Tight tolerances ensure smooth operation in high-speed applications |
| Vibration Levels: Z1V1 to Z3V3 | Ultra-low noise — ideal for precision machinery & automation |
| Lubrication: Grease or Oil Compatible | Extended service life with minimal maintenance intervals |
| Separated Design | Easy installation, disassembly & inspection — reduces downtime |
| Non-Aligning Radial Bearing | Superior rigidity & load capacity under pure radial loads |
| Origin: Japan (NTN Brand) | Stringent JIS/ISO manufacturing control & traceable quality |
| Applications: Gearboxes, Motors, Pumps, Rolling Mills, Conveyors | Proven reliability in demanding continuous-operation environments |
Why choose this NTN series over generic alternatives? Unlike economy bearings, these feature micro-ground rollers, optimized internal geometry, and strict vibration screening — delivering 30% longer L10 life per ISO 281. All units are 100% tested for clearance, rotation torque, and acoustic emission.
FAQ: Q: Are these compatible with SKF mounting dimensions? A: Yes — ISO-standardized bore/OD/shaft fits. Q: Can they handle axial displacement? A: NU/NUP types permit limited axial movement; N/NJ/NF do not. Q: What’s the max speed rating? A: Up to 3,200 rpm (grease-lubricated, light load). Q: Is custom packaging available? A: Yes — OEM carton/pallet labeling supported.
