Please pay attention to the following matters during the use and installation of the hub bearing.
1. There is a magnetic thrust ring in the seal ring equipped with the ABS device bearing. The thrust ring cannot be impacted, impacted or collided with other magnetic fields. Remove from the box before installation and keep them away from magnetic fields, such as electric motors or power tools. When installing these bearings, observe the ABS alarm needle on the instrument panel through the road condition test to change the operation of the bearing.
2 The hub bearing with ABS magnetic thrust ring, in order to determine which side of the thrust ring is installed, you can use a light and small thing * near 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.
3. Many bearings are sealed. These bearings do not need to be greased throughout their life. 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 to add. 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. 10. When installing the lock nut, the torque varies greatly depending on the bearing type and the vertical bearing housing.
