Why Choose This High-Precision Wheel Hub Bearing?
Engineered for reliability and performance, this premium wheel hub bearing delivers OEM-grade precision for FIAT, Ford, and Chrysler vehicles — now available through SKF-authorized distribution.
| Description | Key Value |
|---|---|
| Core Models | DAC30640042 RZ / DAC30640037 ZZ / DAC30650021 2RS |
| Dimensions (mm) | 37 × 72 × 37 — optimized for compact axle assemblies |
| Bearing Type | Double-row radial, unseparated hub unit — enhanced rigidity & load capacity |
| Precision Grade | P0 to P2 (ABEC-1 to ABEC-9 equivalent) — ultra-low runout & noise |
| Vibration Class | Z1V1–Z3V3 certified — ideal for EVs & high-speed applications |
| Lubrication | Premium long-life grease or oil-compatible — sealed for life |
| Material | GCr15 bearing steel (ISO 683-17), heat-treated & hardened |
| Sealing Options | RZ (rubber contact), ZZ (metal shield), 2RS (dual rubber seal) |
| Origin & Compliance | Made in China under ISO 9001 & IATF 16949; HS Code 8482109000 |
| OEM/ODM Support | Custom branding (BDL), packaging, and spec alignment — fast lead time |
Applications: Front/rear wheel hubs for passenger cars, light commercial vehicles, and EV platforms requiring low friction, high-speed stability, and extended service life.
Why It Stands Out: Unlike generic alternatives, this bearing features tighter dimensional tolerances, superior raceway surface finish, and batch-tested vibration/noise profiles — verified against SKF 3200 series benchmarks.
Frequently Asked Questions:
• Is preload pre-set? Yes — factory-adjusted for zero play.
• Can it replace SKF VKBA 3642? Yes — identical fit, form, and function.
• What’s the expected L10 life? ≥ 120,000 km under standard loads.
• Are samples available? Yes — contact us with your vehicle model and VIN.
