(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 bearing wheel shaft has been rotating through the shaft sleeve, and the wheel body needs to be lubricated by adding oil, but if the sealing ring is not good, it is easy to cause oil leakage, so that the shaft and the shaft sleeve are easy to wear without lubrication. The product cannot be used. The reasons for oil leakage are as follows: 1. Unqualified floating oil seal; 2. Insufficient roundness of the product bushing; 3. Insufficient luster of the support shaft; 4. Gear oil is not up to standard; 5. Processing size tolerance and so on. The above-mentioned problems will cause oil leakage from the supporting wheel.
