The front wheel bearings of motorcycles and electric vehicles are often broken, what to do

wallpapers Industry 2020-10-27

The front wheel bearings of motorcycles and electric vehicles are not durable, and they break down soon after they are replaced. If the problem is that there is a large clearance between the bearing position of the rim and the outer ring of the bearing, then the rim can only be replaced. To solve this problem, if there is a gap between the two parts, but it is not large, you can put a few very thin cans around the rim, so that the rim and the outer ring of the bearing can be fixed after the bearing is installed. Tighter, which makes the bearing more durable.

There is also a situation where the rim and the bearing are tightly fixed, but the bearing will be broken after a short time. I often encounter this problem when repairing a car. In addition to the poor quality of the parts themselves, generally The steel sleeve between the two bearings is a bit short. How can I say that when the two bearings are installed at the bottom of the rim, the middle steel sleeve is still very loose, and it can’t get up to interact with the two bearing inner sleeves. As an integral function, in this case, when the front wheel screw shaft is tightened, the new bearing ball is subjected to left and right force in addition to the up and down force. The ball wears quickly, so the bearing breaks quickly.

The solution is to change a steel sleeve a bit longer than the original one, or add an iron washer with the same inner diameter as the bearing to the steel sleeve.
