5. When installing the bearing, it should be in a clean and tidy environment. The entry of fine particles into the bearing will also shorten the service life of the bearing. It is very important to maintain a clean environment when replacing bearings. It is not allowed to hit the bearing with a hammer, and be careful not to drop the bearing on the ground (or similar mishandling). The condition of the shaft and bearing housing should also be checked before installation, as even a small amount of wear can lead to poor fit, which can lead to early failure of the bearing.
6. For the hub bearing unit, do not attempt to disassemble the hub bearing or adjust the sealing ring of the hub unit, otherwise the sealing ring will be damaged and water or dust will enter. Even the raceways of the sealing ring and inner ring are damaged, resulting in permanent failure of the bearing.
7. There is a magnetic thrust ring in the sealing ring equipped with the bearing of the ABS device. This thrust ring cannot be collided with, impacted or collided with other magnetic fields. Take them out of the box before installation and keep them away from magnetic fields, such as motors or power tools in use. When installing these bearings, change the operation of the bearings by observing the ABS alarm needle on the instrument panel through a road test.
8. For the hub bearing equipped with ABS magnetic thrust ring, in order to determine which side the thrust ring is installed on, a small object can be used to approach the edge of the bearing, and the magnetic force generated by the bearing will attract it. When installing, point the side with the magnetic thrust ring inward, facing the sensitive element of the ABS. NOTE: Improper installation may result in the malfunction of the brake system.
9. Many bearings are sealed, and these bearings do not need to be greased throughout their life. Other unsealed bearings such as double row tapered roller bearings must be lubricated with grease during installation. Due to the different sizes of the inner cavity of the bearing, 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 there is too much grease, when the bearing rotates, the excess grease will seep out. General experience: During installation, the total amount of grease should account for 50% of the bearing clearance.
10. When installing the lock nut, the torque varies greatly due to the different bearing types and bearing seats. Pay attention to the relevant instructions.
