NISSAN Cube TIIDA 40202EL000 Front Wheel Hub bearing
Low friction torque
The important measure to reduce the fuel consumption of the automobile is to design the hub bearing with low friction torque. The main factors affecting the friction torque of the bearing are the type of bearing and the preloading load. The bearing seal also accounts for a large proportion of the friction torque component. Therefore, improving the seal design and reducing the friction torque can significantly improve the performance of the hub bearing. The wheel bearing has been developed from the first generation to the latest fourth generation, and the friction torque is gradually reduced.
During the maintenance process, it is often found that some vehicles have large running noise, and the tires are checked for no abnormal wear, and there is no abnormal noise in turning the wheels on the lift. This phenomenon is often caused by abnormal damage of the hub bearing. The so-called abnormality refers to the bearing damage caused by the installation.
