Description
Restore factory wheel alignment and eliminate hazardous hub play across your commercial fleet with the genuine FAG Commercial Vehicle Wheel Hub Bearing & Truck Hub Unit. Engineered specifically for heavy-duty commercial trucks, multi-axle freight haulers, and transit coaches, this OE-grade integrated hub unit combines pre-adjusted double-row bearings, heavy-duty mounting flanges, and integrated high-performance seals into a single maintenance-free assembly. Pitted raceways, spalled steel rollers, incorrect bearing pre-load, or degraded hub seals cause deep roaring noises, excessive wheel wobble, high operating temperatures, and sudden axle seizure. This original FAG truck hub unit solves those mechanical failures directly. It features premium case-hardened 100Cr6 bearing steel, optimized tapered or angular contact roller geometry, and multi-lip cassette seals to deliver uniform stress distribution, ultra-low friction torque, and uncompromised fleet transport reliability.
Technical Parameters
| Category | Specifications & Technical Details |
| Pre-Adjusted Double-Row Bearing Architecture | We calibrate clearance and preload at the factory using precision equipment. This removes the tedious manual adjustment steps of traditional tapered bearings. As a result, the unit reaches optimal working condition the moment it is installed. |
| High-Purity Vacuum-Degassed 100Cr6 Bearing Steel | We manufacture the inner and outer rings and rolling elements from high-purity quenched bearing steel. The surface achieves extremely high hardness and wear resistance, while the core retains good toughness to withstand heavy-load impact. |
| Integrated Cassette Multi-Lip Hub Seal | We use an integrated cassette seal design with multi-stage labyrinth lips and a dust cover. It completely blocks mud, fine sand, and high-pressure wash water intrusion. Moreover, it prevents grease leakage. |
| High-Strength Forged Integral Flange | We hot-forge the hub mounting flange from high-strength alloy steel. It delivers extremely high torsional and shear strength. Therefore, it perfectly carries the huge lateral loads of heavy truck sharp cornering and braking. |
| Integrated ABS/EBS Magnetic Encoder | We integrate a high-precision multi-pole magnetic pulse ring and sensor target wheel inside the hub. It transmits accurate wheel speed signals to the vehicle brake computer in real time. As a result, it ensures precise ABS system intervention. |
Applicable Car Brands & Models
Common warning symptoms include:
Deep Roaring or Humming Noise: A constant low-pitched rumbling noise from the wheel end that increases in volume and pitch with vehicle speed.
Excessive Wheel Hub Play: Noticeable looseness or wobbling when shaking the tire vertically or horizontally while lifted on a jack.
ABS or Traction Control Warning Lights: Sensor signal loss triggered by internal encoder wear, metal debris accumulation, or bearing looseness.
Grease Leakage Around Hub Flange: Discolored grease leaking past worn cassette seals onto the brake components.
Unitized hub assemblies come pre-adjusted and pre-greased from the factory, eliminating the need for manual bearing preload adjustment during installation. This design reduces maintenance errors, prevents contamination, and significantly extends operational lifespan.
No. Unitized truck hub assemblies are sealed, pre-set modular units. If internal raceways, rollers, or seals fail, you must replace the complete FAG hub unit assembly according to professional workshop repair guidelines.
Our 1-year warranty covers all raceway spalling, internal roller fatigue fracture, cage damage, cassette seal material defects, ABS encoder signal failure, and non-artificial mechanical faults under normal operating conditions. If a unit fails within 12 months, we provide prompt replacement or warranty processing upon inspection.
