5. The bearing should be installed 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 improper handling). The condition of the shaft and the bearing seat should also be checked before installation. Even slight abrasion can lead to poor fit and cause early bearing failure.
6. For the hub bearing unit, do not attempt to disassemble the hub bearing or adjust the seal ring of the hub unit, otherwise the seal ring will be damaged and water or dust will enter. Even the raceways of the sealing ring and the inner ring are damaged, causing permanent failure of the bearing.
7. There is a magnetic thrust ring in the sealing ring of the bearing equipped with ABS device. This thrust ring cannot be collided, impacted or collided with other magnetic fields. Take them out of the packaging box before installation and keep them away from magnetic fields, such as motors or power tools used. When installing these bearings, observe the ABS alarm pin on the instrument panel through a road condition test to change the operation of the bearings.
8. For wheel hub bearings equipped with ABS magnetic thrust ring, in order to determine which side the thrust ring is installed on, you can use a small object* near 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 toward the inside, facing the sensitive element of ABS. Note: Incorrect installation may result in failure of the brake system.
9. Many bearings are sealed. This type of bearing does not need to be greased throughout its life. Other non-sealed 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, the excess grease will leak out when the bearing rotates. General experience: When installing, the total amount of grease should account for 50% of the bearing clearance.
10. When the lock nut is installed, the torque varies greatly due to the different bearing type and bearing seat
