A wheel hub is an integral part of a car's wheel assembly, located at the center of the wheel. It serves several important functions:
Functions of Wheel Hub
Connection and Support: The wheel hub is fixed to the steering knuckle or axle and supports the rotation of the wheels through a bearing system, ensuring flexible movement.
Load Bearing: The wheel hub bears the weight of the vehicle itself, as well as dynamic loads such as torque and impact generated during acceleration, deceleration, and turning.
Sensor Integration: In modern cars, some wheel hubs also integrate electronic devices such as ABS speed sensors to monitor wheel speed and rotation direction, enabling advanced driving assistance systems such as Anti-lock Braking System (ABS), Traction Control System (TCS), and Electronic Stability Program (ESP).
Brake Component Installation: In disc brake systems, the brake rotors are typically mounted on the wheel hub, while in drum brake systems, the wheel hub may contain part of the structure of the brake drum.
Safety Fastening: The wheel hub securely fastens the tire to the axle with bolts or a center locking device, ensuring that the tire will not come off.

How to Choose a Wheel Hub Compatible with Your Vehicle
Vehicle Model and Year: Determine the specific model and year of your car, as different models and years may have different specifications for the wheel hub.
OEM Number or Part Number: Look up the Original Equipment (OE) number or aftermarket part number provided by the manufacturer, which is an important reference for selecting a compatible wheel hub. This information can be found in the car manual or on the manufacturer's website.
Dimensional Parameters: Refer to the technical specifications table mentioned above.
Compatibility with Brake System: If your vehicle is equipped with an ABS system or specific types of brake discs such as ventilated or perforated discs, the wheel hub should be able to accommodate these components and may require a corresponding sensor installation position.
