Introduction
High-precision cylindrical roller bearing (Model NUP319EM), ideal for heavy radial loads. Features separated design, P0–P2 precision ratings, low vibration (Z1V1–Z3V3), and OEM/ODM service. Made in China, branded BDL.Key Specifications & Advantages of NUP319EM Cylindrical Roller Bearings
| Description | Core Value |
|---|---|
| Model: NUP319EM (ISO standard, interchangeable with SKF NU319EM/NJ319EM) | Direct OEM replacement for SKF — seamless integration, zero redesign needed |
| Bore × OD × Width: 95 × 200 × 45 mm | Precise dimensional compliance ensures perfect fit in existing SKF-driven machinery |
| Material: High-carbon chromium bearing steel (GCr15 equivalent) | Superior hardness & fatigue resistance — 2x service life vs. standard grade |
| Radial load capacity: Up to 325 kN (dynamic), 360 kN (static) | Optimized roller profile & heat treatment deliver exceptional load handling |
| Precision grade: P0/P6 available (ABEC-1/ABEC-3 equivalent) | Tight tolerances ensure low vibration (Z2V2 certified) and quiet operation |
| Lubrication: Grease or oil compatible — sealed or open variants | Extended relubrication intervals reduce maintenance downtime |
| Separated design with fixed axial location (NUP type) | Enables precise shaft positioning — ideal for gearboxes & motors |
| Applications: Industrial gearboxes, wind turbines, mining conveyors, paper mills | Proven reliability in high-shock, continuous-duty environments |
| Quality assurance: ISO 9001, 100% dimensional & noise testing | Each batch traceable — full test reports provided upon request |
| Differentiator: BDL’s proprietary surface finishing + cage optimization | Lower friction & higher speed capability vs. generic alternatives |
FAQ: Is this bearing suitable for high-speed applications? Yes — up to 3,800 rpm (oil-lubricated, P6 grade). Does it support axial displacement? The NUP319EM accommodates axial expansion on one side only — consult our engineering team for dual-direction needs. Are samples available? Yes — free technical samples for qualified industrial buyers.
