Hub Unit Bearing suppliers give a brief explanation of how a hub unit bearing works:
Supporting the vehicle’s weight:
The hub unit bearing assembly’s primary function is to carry the weight of the vehicle. The wheel hub is the central part of the assembly that connects to the wheel and supports the weight of the vehicle. The bearings are positioned between the hub and the axle, allowing the hub to rotate freely around the axle.
Reducing friction:
The bearings within the hub unit bearing assembly are designed to minimize friction as the wheel hub rotates. These bearings are usually either ball bearings or tapered roller bearings, which are designed to handle both radial and axial loads. The bearings are lubricated with grease and sealed to prevent contaminants from entering and maintain their performance over time.
Maintaining wheel alignment:
The hub unit bearing assembly contributes to maintaining proper wheel alignment. If the bearings wear out or get damaged, it can cause poor wheel alignment, leading to uneven tire wear, decreased fuel efficiency, and compromised handling.
Incorporating wheel speed sensor:
In modern vehicles, the hub unit bearing assembly often includes a built-in wheel speed sensor. This sensor plays a critical role in the functioning of the Anti-lock Braking System (ABS) and other vehicle stability systems. The sensor measures the rotational speed of the wheel and sends this information to the vehicle’s Electronic Control Unit (ECU), which then adjusts the braking force accordingly to prevent wheel lockup and maintain vehicle stability.
The hub unit bearing is an essential component that supports the vehicle’s weight and ensures the smooth rotation of the wheels.Regular maintenance and replacing worn or damaged hub unit bearings are crucial to ensuring the safe and efficient operation of your vehicle.
