The automotive wheel hub unit manufacturing process focuses on “high impact resistance and integrated precision” to meet the rigorous demands of automotive driving. High-carbon chromium bearing steel is selected for its material and vacuum refined to remove impurities, ensuring the substrate’s strength, toughness, and uniformity.
Key components are machined using five-axis CNC grinding machines, achieving IT4-level geometric accuracy for the inner and outer raceways. Flange bolt holes are machined using CNC drilling and tapping centers, achieving a coaxiality of ≤0.01 mm. Surface treatments such as phosphating or electrophoresis enhance corrosion resistance.
Components undergo full quenching and tempering followed by cryogenic treatment to prevent deformation under heavy loads. Assembly is completed in a Class 1000 cleanroom. ABS sensor integration ensures precise signal calibration and preload control to ensure rotational accuracy. The finished product undergoes dynamic balancing, waterproof and dustproof sealing, and a lifespan test exceeding 100,000 cycles, complying with IATF16949 standards. Suitable for sedans, SUVs, and other vehicles, ensuring stable and safe driving.
