Product Details
NTN N2320EM Series Cylindrical Roller Bearings – High-Precision Radial Solutions
Engineered for demanding industrial applications, the NTN N2320EM series (including NJ2320EM, NF2320EM, NU2320EM, NUP2320EM) delivers unmatched radial load capacity, precision, and reliability. Built in Japan from premium bearing steel, these non-aligning, separable cylindrical roller bearings support heavy-duty rotating equipment where rigidity and low friction are critical.
| Description | Key Specification |
|---|---|
| Precision & Grade | P0 to P2 (ABEC-1 to ABEC-9 equivalent) |
| Bore × OD × Width | 100 × 215 × 73 mm (per specification) |
| Load Direction | Pure radial — ideal for gearboxes, motors, pumps |
| Separability | Fully separable design — simplifies mounting & maintenance |
| Lubrication Flexibility | Compatible with grease or oil |
| Vibration Class | Z1V1 to Z3V3 — optimized for quiet, smooth operation |
| Material | High-carbon chromium bearing steel (JIS SUJ2) |
| OEM/ODM Support | Full customization & branding available |
| Origin & Traceability | Made in Japan — full HS Code 8482500090 compliance |
| Quality Assurance | 100% tested; ISO 9001 & IATF 16949 certified production |
Why choose NTN over alternatives? Superior dimensional stability, tighter raceway tolerances, and proprietary heat treatment deliver longer service life vs. generic brands — especially under high-speed or shock-load conditions.
FAQ: Q: Are N2320EM variants interchangeable? A: Yes — same boundary dimensions, but differ in flange configuration (NJ = fixed loc. on OD, NU = floating, NUP = combined axial guidance). Q: Can these replace SKF NU320E? A: Yes — direct dimensional match; NTN offers higher base precision as standard.
