Key Specifications & Advantages of Customizable Heavy-Duty Needle Roller Bearings (AXK5578/6085/6590/7095/75100)
| Description | Core Value |
|---|---|
| Radial load design with ultra-thin cross-section (e.g., 70×95×4 mm) | Maximizes space efficiency in compact machinery without compromising load capacity |
| Bearing steel construction (GCr15 equivalent) | Ensures high hardness, wear resistance, and extended service life under heavy-duty cycles |
| Ringless design (no outer/inner ring) | Enables direct mounting onto hardened shafts/housings — reduces weight and assembly cost |
| Precision grades P0–P2 & clearances C0–C4 | Supports high-speed, low-vibration applications including robotics and precision gearboxes |
| Grease or oil lubrication compatible | Flexible maintenance integration for OEMs across automotive, textile, and packaging lines |
| 1,000,000 pcs/year production capacity | Guarantees fast lead time (3–7 days) and consistent batch-to-batch quality control |
| ISO/TS 16949-aligned manufacturing (China origin, HS 8482102000) | Meets global automotive supply chain compliance requirements |
| OEM/ODM support with BDL branding | Enables private labeling and custom engineering — ideal for SKF distribution partners |
| Closed-type sealed structure | Prevents contamination ingress and retains lubricant — critical for dusty industrial environments |
| Multi-model standardization (AXK5578 to AXK75100) | One-stop sourcing for scalable bearing families — simplifies inventory & logistics |
These needle roller bearings excel in transmission systems, cam followers, planetary carriers, and linear motion modules. Unlike generic imports, our AXK series features tighter raceway roundness tolerance (10,000 rpm? With P4/C3 + synthetic grease: confirmed up to 12,500 rpm (test report available); Do you supply matched sets for axial preloading? Yes — contact us for paired AXK+AS washer configurations.
