Product Details
High Precision N307EM NUP307EM Cylindrical Roller Bearing – SKF-Grade Performance
| Description | Key Value |
|---|---|
| Precision & Tolerance | P0–P2 grade, ultra-low vibration (Z1V1–Z3V3), ideal for high-speed spindles |
| Robust Construction | High-carbon chromium bearing steel (GCr15), hardened to HRC 60–64 |
| Optimized Dimensions | 35×80×21 mm (bore × OD × width); compact yet load-dense design |
| Radial Load Capacity | Superior dynamic load rating: 92.3 kN — 30% higher than standard Grade P0 |
| Separable Design | NUP configuration: fixed axial location on both sides + easy mounting/dismantling |
| Lubrication Flexibility | Compatible with premium grease (e.g., SKF LGHP 2) or circulating oil systems |
| Application Scope | Machine tools, gearboxes, wind turbines, mining conveyors, and precision pumps |
| Quality Assurance | 100% dimensional inspection, noise testing, and batch traceability (ISO 9001 & IATF 16949 certified) |
| SKF-Compatible Advantage | Interchangeable with SKF NU307ECML/NUP307ECML — same fit, form, function |
| FAQ: Why choose BDL NUP307EM? | Lower friction torque vs. generic brands; tighter raceway roundness (<0.005 mm); extended L10 life by ≥25% |
Engineered for reliability where precision matters — this cylindrical roller bearing delivers SKF-level consistency without the premium markup.
