Knowledge of auto wheel bearing 54KWH01

There is a special type bearing used on cars.We call it wheel hub bearing.Usually used on car wheels. In order to solve the problems of cost, installation and signal quality of wheel speed sensor which provides wheel speed signal to ABS, wheel bearing pulse generator was developed.

The wheel bearing unit is developed on the basis of the standard angle contact ball bearings and cone roller bearings. It integrates two sets of bearings as one. It has good assembly performance, omitted gap adjustment, light weight, compact structure, load capacity Large, the advantages of lubricating fat for sealing bearing can be installed in advance, omitting external wheels sealing and exempting maintenance. It has been widely used in cars.

Precautions for the use and installation of wheel bearing:
1. In order to maximize the safety and reliability, no matter how old the vehicle is, it is necessary to check whether there is an early warning signal for wear: including any friction noise at the time of rotation or the suspension combination wheel is decelerated abnormally when turning.
2. If the noise emitted by the wheel bearing site, first find the location of the noise. If the noise in the bearing is confirmed, the bearings may be damaged and need to be replaced.
3. Because the working conditions on both sides of the front wheel hub are similar, even if only one bearing is broken, it is recommended to replace it.
4. The wheel bearing is more sensitive, and under any circumstances, the correct method and the appropriate tool need to be adopted.
5. In a clean and tidy environment, small particles entering the bearings should also shorten the service life of the bearings in a clean and tidy environment. It is very important to maintain a clean environment when replacing bearing.
6. Do not disassemble the sealing ring for the wheel bearing unit, otherwise the sealing ring will be damaged and the water or dust will enter.
7. There is a magnetic thrust ring in the sealing ring equipped with the ABS device bearing. This thrust ring cannot be collided, impacted or collided with other magnetic fields.
8. Many bearing is sealed. Such bearing does not need to add fat in the entire life period. Other non -sealing bearing must be cheerful and lubricated when installing. General experience: When installation, the total amount of fats accounts for 50%of the gap between the bearing.
9. Due to the difference between the bearing type and the bearing seat when installing the locking nut, the torque is very different. Pay attention to the relevant instructions.
