Key Specifications & Advantages of SKF-Grade Axk Series Needle Roller Bearings
| Feature | Value / Benefit |
| Ultra-Compact Design | No inner/outer ring — saves space, ideal for limited-axis applications (e.g., transmission forks, clutch hubs) |
| Precision Dimensions | Axk5070: 50×70×3 mm — tight tolerances (P0–P2 grade) ensure smooth high-RPM operation |
| Bearing Steel Construction | GCr15 chrome steel — hardened to HRC 60–64 for extended fatigue life and wear resistance |
| Radial Load Capacity | Optimized needle arrangement delivers 2.3× higher dynamic load vs. standard thrust washers |
| Lubrication Flexibility | Pre-greased or oil-lubricated — compatible with industrial gear oils and synthetic greases (NLGI #2) |
| Closed-Type Sealing | Dust- and leak-resistant design — reduces maintenance frequency by up to 40% |
| Global Compliance | HS Code 8482102000 — certified for EU CE, ISO 9001, and RoHS; manufactured in ISO-certified China facility |
| OEM/ODM Ready | Custom branding (BDL or your logo), packaging, and clearance options (C0/C3/C4) available in 3–7 days |
| Why Choose Us Over Generic Brands? | SKF-aligned engineering, 1M units/month capacity, full traceability, and real-time technical support — not just drop-shipping |
Engineered for automotive transmissions, agricultural PTOs, and precision machine tools — these axially loaded needle bearings deliver unmatched stiffness-to-size ratio. Unlike generic alternatives, our Axk series features optimized roller end geometry and controlled surface roughness (<0.2 µm Ra) to minimize edge stress and prevent premature spalling. All units undergo 100% dimensional inspection and noise testing (≤28 dB at 1800 rpm). Need volume pricing, CAD files, or application validation? Send your inquiry now — our engineers reply within 2 hours.
