The application range and amount of hub bearing unit are increasing day by day, and now it has developed to the third generation: the first generation is composed of double row angular contact bearings. The second generation has a flange on the outer raceway for fixing the bearing, which can simply sleeve the bearing onto the axle and fix it with nuts. Make the maintenance of the car easier. The third generation wheel hub bearing unit adopts the combination of bearing unit and anti lock brake system ABS. The hub unit is designed with an inner flange and an outer flange. The inner flange is fixed on the drive shaft with bolts, and the outer flange installs the whole bearing together. Worn or damaged wheel hub bearing or wheel hub unit will cause inappropriate and costly failure of your vehicle on the road, and even harm your safety

Maintenance attention
During the maintenance process, it is often found that some vehicles have large driving noise. Check whether the tires are abnormally worn and whether there is obvious abnormal noise when rotating the wheels on the lift. This phenomenon is often caused by abnormal damage of hub bearing. The so-called abnormal refers to the bearing damage caused by installation. The front wheel bearing of an automobile is generally a double row ball bearing. If a hammer is used to knock and install the bearing when installing the bearing, or if the bearing is installed by pressing the inner ring of the bearing when installing the bearing into the bearing seat, it will cause damage to the bearing raceway on one side. Noise is generated when the vehicle is running, and when the wheel is off the ground, no obvious noise can be heard because there is a better side of the raceway. Correct installation and operation is the key to long bearing life.

Method of extending the bearing’s lifetime:

1. The installation is correct, that affects precision, life, performance. And fill the bearing with lubricant after installation.

2. Don't allow strong impact, such as hammer striking, transfer roller pressure 

3. Use the accurate installation tool, avoid to use cloth kind and short fibers

4. Lubricate the bearing to avoid rust with high quality mineral oil, especially in summer

5. General inspection, such as the surrounding temperature, vibrate, noise inspection

7. Bearing should not be ultra cooled.
