NSK NU424EM/NJ426EM/NU426EM/NJ428EM/NU428EM Cylindrical Roller Bearings – High-Precision Radial Solutions
Engineered for extreme radial loads and high-speed operation, these NSK cylindrical roller bearings deliver unmatched reliability in demanding industrial environments.
| Description | Key Specification |
|---|---|
| Core Model Range | NJ426EM, NU424EM, NU426EM, NJ428EM, NU428EM |
| Dimension (mm) | 130 × 340 × 78 (e.g., NJ426EM) |
| Material & Precision | High-carbon chromium bearing steel; P0–P2 precision grades available |
| Load Capacity | Ultra-high radial load rating; non-thrust (NJ-type) or full-complement (NU-type) designs |
| Structure & Seal | Single-row, cylindrical rollers, open configuration (no seals/grease) |
| Operating Temp. | –30°C to +150°C (with appropriate lubrication) |
| Applications | Electric motors, gearboxes, pumps, wind turbines, mining equipment, rolling mills |
| Quality Assurance | Manufactured in Japan; ISO 9001 & IATF 16949 certified; 100% dimensional & noise testing |
| Differentiator vs. Generic Brands | Superior roller profile control → 30% longer L10 life; lower vibration (Z2/V2 grade compliant) |
| FAQ: Can it replace SKF NU326E? | Yes — identical boundary dimensions and load ratings; consult our cross-reference chart for full interchangeability. |
Trusted by Tier-1 OEMs globally, NSK’s EM-series offers optimized internal geometry and surface finish for reduced friction and extended service intervals. Unlike budget alternatives, these bearings feature strict roller diameter variation control (<0.5μm), ensuring quiet, smooth operation even under shock loads.
