Product Details
NTN Japan-Made High-Precision Cylindrical Roller Bearings (NUP2315EM Series)
| Description | Key Value |
|---|---|
| Precision & Origin | Made in Japan — strict JIS/ISO standards; P0–P2 precision grades available |
| Core Structure | NUP-type: fixed double-flanged outer ring + loose inner ring — enables axial location + high radial load capacity |
| Dimensions (mm) | Bore: 75 | OD: 160 | Width: 55 — compact yet robust for space-constrained OEMs |
| Material & Hardness | High-carbon chromium bearing steel (SUJ2 equivalent); hardened to HRC 60–64 |
| Load Performance | Radial-only, non-aligning — optimized for heavy-duty industrial shafts & gearboxes |
| Lubrication Flexibility | Pre-greased or oil-lubricated — compatible with SKF LGMT 2, Shell Gadus S2 V220 |
| Vibration Control | Z2V2/Z3V3 certified — ultra-low noise for precision machine tools & pumps |
| Separability | Fully separable design — simplifies mounting, maintenance & replacement |
| Quality Assurance | 100% dimensional inspection + dynamic testing; ISO 9001 & IATF 16949 certified production |
| SKF Cross-Reference | Direct interchange with SKF NUP 315 ECML — same footprint, higher fatigue life |
Engineered for demanding applications: wind turbine gearboxes, CNC spindles, mining conveyors, and hydraulic pumps. Unlike generic Chinese rollers, NTN’s proprietary heat treatment and raceway superfinishing deliver 32% longer L10 life (per ISO 281). All units are traceable via batch ID and shipped in anti-rust VCI cartons on pallets. Questions? Contact our NTN-certified application engineers now for technical support or custom clearance specs.

Application Design
EngineeringOur engineers analyze your operating conditions -- load, speed, temperature, environment -- and select or design the optimal bearing solution to maximize service life and reduce total cost of ownership.
Custom Modification
7-Day TurnaroundNeed non-standard dimensions, special materials, or modified clearances? We can modify standard SKF bearings or manufacture fully custom solutions with a 7-day prototype turnaround.
Failure Analysis
DiagnosticsWhen bearings fail prematurely, our team conducts root-cause analysis using advanced diagnostic tools to identify the failure mode and recommend corrective action.
Predictive Maintenance
Up to 40% Less DowntimeWe deploy vibration monitoring, thermal imaging, and oil analysis programs that detect bearing deterioration early -- reducing unplanned downtime by up to 40%.
On-site Installation
Global CoverageProper installation is critical to bearing performance. Our certified technicians provide on-site installation support, alignment verification, and operator training worldwide.
Lifecycle Support
Enterprise SLAFrom initial selection through end-of-life, our dedicated account managers provide scheduled maintenance plans, re-lubrication programs, and replacement forecasting for enterprise clients.
