Bearing due to excessive clearance, bearing inner ring and ball scattered. Only the bearing outer circle is left, and it is still on the fixed support. It's a lot of trouble to dismantle it in the past.
Previously, we usually used electric welding for this kind of situation, welding something to the bearing outer circle, and then by tapping something welded to the bearing outer circle, the bearing outer circle together pull out. For example, the needle roller bracket in the engine, or the bearing bracket in the engine will mostly take this method. The result is relatively good. However, this method has its limitations, we need to remove the bearings to be welded to place.
If a bigger bearing like the 6205 on a tricycle's half-axle is on the road, then this method is not feasible. After all, we have nowhere to find an electric welder on the road, and even if there is an electric welder, there is no need to get electricity anywhere on the road.
Of course, there are problems, there will be demand, and naturally some people will solve this demand. We can use a more convenient method, there is a special electric tricycle bearing cylindrical removal tool.
