Product Details
Key Specifications & Why SKF-Grade NUP310EM Cylindrical Roller Bearings Stand Out
| Description | Core Value |
|---|---|
| Model: NUP310EM (ISO Standard) | Precise axial location + high radial load capacity |
| Bore × OD × Width: 50 × 110 × 27 mm | Direct replacement for SKF NU310EM/NUP310EM |
| Material: High-Carbon Chromium Bearing Steel (GCr15) | Hardness HRC 60–64, fatigue-resistant |
| Precision Grades: P0, P6, P5 (ABEC-1 to ABEC-5) | Low vibration (Z2V2 certified), ideal for precision machinery |
| Lubrication: Grease or oil-compatible | Extended service life, minimal maintenance |
| Load Type: Radial-only, non-self-aligning | Optimized rigidity for CNC spindles & gearboxes |
| Separable Design | Easy installation, independent mounting of inner/outer rings |
| Origin & Compliance: Made in China, HS 8482500090 | Export-ready; meets ISO 9001 & IATF 16949 manufacturing standards |
| Applications | Industrial pumps, wind turbine gearboxes, mining conveyors, textile machines |
| Why Choose Us Over Generic Brands? | 100% dimensional & tolerance compliance with SKF catalog specs — verified via CMM & spectral analysis |
Engineered for reliability under heavy radial loads and high-speed operation, our NUP310EM bearings deliver SKF-equivalent performance at competitive trade pricing. Every batch undergoes 100% noise, rotation, and clearance testing — no exceptions. Unlike off-spec imports, our units feature consistent heat treatment, optimized roller profiling, and strict cage concentricity control. Frequently asked: “Can this replace SKF NU310EM?” Yes — identical mounting dimensions, load ratings, and interchangeability per ISO 15. “Is preload adjustable?” Yes — separable design allows precise axial clearance tuning. “What’s the max speed?” Up to 6,200 rpm (grease-lubed, P6 grade).
