A. 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;
B. 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.
There are several reasons for oil spills:
1). Unqualified floating oil seal
2). The roundness of the product sleeve is not enough
3). The fulcrum has insufficient gloss
4). Gear oil is not up to standard
5). Processing size tolerance issues, etc. will cause oil leakage on the rollers
