What Should We Pay Attention to after the Development of Wheel Bearing Technology? What Should We Pay Attention to after the Development of Wheel Bearing Technology?

With the development of technology, car hub units have been widely used in cars. The use and use of hub bearing units is growing and is now in its third generation. The first generation consisted of double row angular contact bearings. The second generation has a flange for fixing the bearing on the outer raceway, which can be simply fixed to the axle by a nut. When the lock nut is installed, the magnitude of the torque varies greatly depending on the type of bearing and the bearing housing, making the maintenance of the vehicle easy. The third-generation hub bearing unit is equipped with a bearing unit and an anti-lock brake system ABS.

For the wheel bearing equipped with the ABS magnetic thrust ring, in order to determine which side of the thrust ring is mounted, a light and small object can be used to close the edge of the bearing. The magnetic force generated by the bearing will attract it. When installing, point the side with the magnetic thrust ring to the inside, facing the sensitive component of the ABS. Note: Improper installation may result in malfunction of the brake system.

Many wheel bearings are sealed and do not require grease for the entire life of the bearing. Other unsealed bearings such as double row tapered roller bearings must be greased during installation. Because the inner cavity of the bearing is different in size, it is difficult to determine how much grease is added. The most important thing is to ensure that there is grease in the bearing. If the grease is too much, when the bearing rotates, the excess grease will seep out. General experience: When installing, the total amount of grease should account for 50% of the bearing clearance.
