Possible issues

(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, resulting in insufficient wear resistance;

(2) Oil leakage. The supporting wheel shaft is constantly rotating through the shaft sleeve, and the wheel body needs to be lubricated with oil. However, if the sealing ring is not good, it is easy to cause oil leakage. This way, the shaft and shaft sleeve are easily worn without lubrication, causing the product to be unusable. There are several reasons for oil leakage: 1. The floating oil seal is not qualified; 2. Insufficient roundness of the product shaft sleeve; 3. Insufficient glossiness of the support shaft; 4. The gear oil does not meet the standard; 5. Processing dimensional tolerances, etc. All of the above issues can cause oil leakage from the supporting rollers.
