Product Details
NTN NUP324EM Cylindrical Roller Bearing – High-Precision Radial Solution
| Feature | Detail |
| Core Application | Heavy-duty industrial gearboxes, wind turbines, mining equipment & steel mill machinery |
| Key Performance | High radial load capacity (C = 540 kN), low friction, P5 precision option available |
| Material & Heat Treatment | Japanese JIS SUJ2 bearing steel, vacuum-degassed + case-hardened for fatigue resistance |
| Design Advantage | NUP-type: Fixed double-flanged outer ring + loose inner ring — enables axial displacement & thermal expansion compensation |
| Dimensional Accuracy | 120 × 260 × 55 mm (d × D × B); tolerance grade ABEC-5 (P5) compliant |
| Lubrication Flexibility | Pre-greased (NLGI #2 lithium complex) or oil-lubricated; compatible with SKF LGMT 2 & Mobilith SHC 100 |
| Quality Assurance | 100% vibration-tested (Z2V2 level), ISO 9001 & IATF 16949 certified production in Japan |
| Differentiator vs. Generic Brands | Superior roller profile grinding → 30% longer L10 life; tighter raceway roughness (Ra ≤ 0.2 μm) |
| Mounting Support | Includes NTN mounting guide & thermal expansion clearance calculator (downloadable) |
| FAQ Highlight | Q: Can it replace SKF NU324ECP? A: Yes — identical envelope dimensions and load ratings; NUP324EM adds axial location capability. |
