NSK N415EM–N416EM Cylindrical Roller Bearings – High-Precision Radial Solutions
| Description | Key Value |
|---|---|
| NJ415EM, NU415EM, NF415EM, NJ416EM, etc. – Interchangeable high-precision variants | |
| Dimensions (d×D×B) | 80 × 200 × 48 mm (standard for N416EM) |
| Material & Hardness | High-carbon chromium bearing steel (SUJ2), hardened to HRC 60–64 |
| Precision Grade | P0 (ABEC-1), optional P6/P5/P4/P2 for ultra-high-speed applications |
| Load Capacity | High radial load + moderate axial (NJ/NF types support single-direction thrust) |
| Separated design — roller & cage assembly detachable from outer ring for easy mounting | |
| Compatible with oil, grease, or dry-film lubricants; open type ensures thermal stability | |
| Application Scope | Industrial gearboxes, motors, pumps, wind turbines, mining conveyors, steel mills |
| Quality Assurance | 100% NSK Japan origin; ISO 9001 & IATF 16949 certified manufacturing |
| Competitive Edge | Lower friction torque vs. generic brands; tighter dimensional tolerances (ΔDmp ≤ 0.015 mm) |
Engineered for reliability under heavy radial loads and high-speed operation, NSK cylindrical roller bearings deliver unmatched precision, longevity, and ease of maintenance. Their separated structure simplifies installation in tight spaces — a critical advantage over non-separable alternatives. Rigorous Japanese quality control ensures consistent performance across batches, while the open design supports flexible lubrication strategies for diverse operating environments.
Frequently Asked Questions:
Q: Are NJ416EM and NU416EM interchangeable? A: Yes — same dimensions, but NJ has flanged inner ring (axial location), NU has no flanges (freely floating).
Q: What’s the max operating temperature? A: Up to 120°C continuous with standard grease; higher with special lubricants.
Q: Do you offer custom cages or coatings? A: Yes — brass, polyamide, or PEEK cages; TiN or DLC coatings available on request.
