SKF FAG Wheel Hub Knuckle Assembly

Bearings are known as the cornerstone of industry, and their importance is unquestionable.

There are tens of thousands of parts in a car, and wherever there are rotating pairs, there are bearings. There are dozens of bearings inside the engine gearbox.

The SKF FAG Wheel Hub Knuckle Assembly is the part that connects the tire (rotating part)/brake disc (rotating part) and the steering knuckle (Knuckle, fixed part). Its main function is to reduce friction for the rotating pair, and also plays a role in transmitting force. It bears very large radial load (vehicle weight) and axial load (lateral force or lateral impact force of the tire during steering).

To determine whether the vehicle's SKF FAG Wheel Hub Knuckle Assembly are damaged, you can use the following two methods:

●Place the vehicle on a lift, rotate the wheels vigorously to see if the wheels are stuck, and evaluate whether the drag torque of the wheels is normal. If the steel ball is poorly lubricated or out of round, it will cause jamming or an increase in drag torque.

● During normal driving of the vehicle, pay attention to whether there is any abnormal noise in the direction of the wheels. If the steel ball is not well lubricated, the first problem that will occur is abnormal noise. If there is no abnormal noise, there is generally no problem.

In addition, since the signal source (magnetic pole or ring) of most current wheel speed sensors is integrated on the SKF FAG Wheel Hub Knuckle Assembly, if there is a problem with the wheel speed signal, the instrument panel will report a fault code and have an ABS fault light point as shown in the figure below. Bright.

So if the ABS fault light is always on, it may be that the magnetic pole of the SKF FAG Wheel Hub Knuckle Assembly is damaged.
