Key Specifications & Advantages of SKF-Grade AXK Series Needle Roller Bearings
| Description | Core Value |
|---|---|
| Ultra-thin section (e.g., 120×155×4 mm) | Maximizes space efficiency in compact machinery designs |
| Radial load-only, cage-guided needle rollers | Ensures precise alignment and low friction under high-speed rotation |
| No inner/outer ring design | Reduces weight & cost; ideal for hardened shaft/housing applications |
| GCr15 bearing steel, heat-treated | Delivers exceptional hardness (HRC 60–64) and fatigue resistance |
| P0 to P2 precision grades available | Meets stringent OEM requirements for CNC, robotics & medical devices |
| C0/C3/C4 radial clearance options | Enables thermal expansion compensation in variable-temp environments |
| Grease or oil lubrication compatible | Supports long maintenance intervals and diverse industrial conditions |
| ISO/ABEC-certified manufacturing | Guarantees dimensional accuracy and interchangeability with SKF AXK |
| Made in China — BDL brand, 1M pcs/year capacity | High-volume reliability with traceable QC and ISO 9001 compliance |
| Common applications: gearboxes, automotive transmissions, printing presses, packaging machines | Proven performance where axial space is constrained but radial rigidity is critical |
Unlike generic needle bearings, our AXK series features tighter raceway surface roughness (Ra ≤ 0.2 μm), optimized roller end geometry for reduced edge stress, and 100% noise-tested batches — ensuring quieter, longer service life. All units are pre-lubricated and sealed to prevent contamination during storage or installation.
FAQ: Q: Are these direct replacements for SKF AXK120155? A: Yes — identical dimensions, load ratings, and mounting interfaces. Q: Can they handle shock loads? A: Optimized for steady radial loads; for intermittent shocks, specify C3 clearance. Q: What’s the max operating temperature? A: Up to 120°C with lithium complex grease.
