Product Details
Key Specifications & Why Choose These Hub Bearings
| Feature | Description |
| Precision Grade | P0–P2 ultra-precision options (exceeding ISO ABEC-9), ideal for high-speed automotive hubs |
| Sealed Design | 2RS / 4RS double-lip nitrile rubber seals — superior dust/moisture resistance vs. open or single-seal competitors |
| Material & Heat Treatment | High-carbon chromium bearing steel (GCr15), vacuum-quenched for ≥62 HRC hardness & fatigue life |
| 37×72×37 mm — exact OEM fit for FIAT, Ford, Chrysler wheel hubs (DAC38700038 / DAC38710039 series) | |
| Vibration Class | Z1V1–Z3V3 certified — ultra-low noise & smooth rotation critical for EV/quiet-vehicle applications |
| Premium lithium complex grease pre-filled; compatible with oil lubrication for extended service intervals | |
| OEM/ODM Ready | BDL-branded, in-stock, fully compliant with ISO 9001 & IATF 16949 — supports private labeling & custom packaging |
| Application Scope | Front/rear wheel hub assemblies, ABS-integrated systems, light commercial vehicles & passenger cars |
| Differentiator | Unseparated double-row unit design — eliminates assembly error, improves axial/radial load capacity by 22% vs. split bearings |
| FAQ | Q: Are these interchangeable with SKF VKBA 3650? A: Yes — identical dimensional & performance specs (37×72×37, P5 grade available). Q: What’s the L10 life at 3,000 rpm? A: ≥120,000 km under standard load conditions. |
