Key Specifications & Benefits
| Description | Core Value |
|---|---|
| Model Range: DAC30640042 RZ / DAC30640037 ZZ / DAC30650021 2RS | Triple-sealed, interchangeable hub bearing units for broad OEM fitment |
| Dimensions: 37×72×37 mm | Exact replacement for FIAT, Ford & Chrysler wheel hubs — zero retrofitting |
| Double-row radial design | Superior load distribution & extended service life under dynamic cornering loads |
| Precision Grade: P0–P2 available | Ultra-low runout (<0.01mm) ensures smooth high-speed rotation & reduced NVH |
| Vibration Class: Z1V1 to Z3V3 | Certified low-vibration performance — critical for EV/ADAS stability |
| Material: GCR15 Bearing Steel | Hardened to 60–64 HRC with uniform microstructure for fatigue resistance |
| Lubrication: Pre-filled grease or oil-ready | Extended relubrication intervals; compatible with synthetic & biodegradable lubricants |
| OEM/ODM Support & 1M pcs/mo capacity | Rapid prototyping, custom branding (BDL), and consistent batch traceability |
| Origin: China (HS Code 8482109000) | ISO 9001 & IATF 16949 certified production — full compliance documentation supplied |
| Unseparated unit construction | One-piece assembly reduces installation errors & field failure risk vs. multi-component kits |
Engineered for front/rear axle applications in passenger cars and light commercial vehicles, these hub bearings deliver exceptional durability in stop-start urban cycles and highway endurance. Unlike generic alternatives, each unit undergoes 100% dynamic testing, preload verification, and seal torque validation. FAQs: Are samples available? Yes. Can we customize packaging/logos? Yes. What’s the typical lead time? 7–15 days ex-works. Ready to verify compatibility or request a technical datasheet? Send your inquiry now.
