dozer bottom track roller easy problems:
1. Wheel body wear. The reason for this situation is that the steel used is unqualified or the hardness of the material during heat treatment is low and the wear resistance is insufficient;
2. Oil leakage. The axle of the bottom track roller has been rotating through the sleeve, and the wheel body should be lubricated with oil, but if the sealing ring is not good, it is easy to produce oil leakage, so that the shaft and the sleeve are easy to wear in the case of no lubrication, resulting in the product cannot be used.
