Product Details
NTN NUP324EM Cylindrical Roller Bearing – High-Precision Radial Solution
| Description | Key Spec / USP |
|---|---|
| Ultra-Precise Radial Load Handling | Rated for heavy radial loads with P0–P2 precision options (JIS/ISO compliant) |
| Optimized Internal Design | NUP-type: Fixed double-flanged outer ring + loose inner ring — enables axial displacement & thermal expansion compensation |
| Japan-Made Bearing Steel | High-carbon chromium steel (SUJ2 equivalent), vacuum-melted, micro-cleaned for 2× service life vs. standard grade |
| Dimensional Accuracy | 120×260×55 mm (ID×OD×W); bore 120 mm, OD 260 mm — fully interchangeable with SKF NU324E/NUP324E |
| Vibration & Noise Control | Z2V2 grade — ideal for high-speed motors, gearboxes, and precision machine tools |
| Lubrication Flexibility | Pre-greased or oil-lubricated; compatible with major synthetic & mineral lubricants (e.g., SKF LGEP2, Mobilith SHC 100) |
| Rigorous Quality Assurance | 100% dimensional inspection + dynamic vibration testing; certified to ISO 9001 & JIS B 1514 |
| Real-World Applications | Wind turbine gearboxes, industrial pumps, rolling mill stands, CNC lathes, and automotive test rigs |
| Differentiator vs. Generic Brands | NTN’s proprietary EM (Enhanced Machinability) cage + optimized roller profile = 35% lower friction torque & 20% higher fatigue life |
| FAQ – Quick Technical Notes | Q: Is it suitable for axial load? A: Only limited bi-directional axial load (via NUP fixed side). Q: Max speed? A: Up to 3,200 rpm (grease), 4,500 rpm (oil). Q: RoHS compliant? Yes — full material traceability provided. |
