When we received this feedback in the early stage, we were also very surprised. As a universal joint shaft manufacturer with more than ten years of experience, judging from the design structure of our cross bag, there is no situation where the oil cannot be added. In addition, we are Before the product is assembled and shipped, the bearings in the four directions of the cross bag will be filled with grease, in order to prevent some customers from not paying attention to maintenance and extending the refueling cycle.

　　The bearing shell and the cross shaft are sealed with double-sided frame oil seals. This mechanical seal is relatively tight, which can ensure that external water and dust will not enter the bearing shell, and the grease in the bearing shell will not overflow, ensuring that the cross shaft and the cross shaft Lubrication system for bearings.

　　The amount of grease that can be stored in the gap in the bearing shell is not much, and it can be filled up in a few seconds with an ordinary pneumatic high-pressure grease gun.Due to the tightness of the skeleton seal, the grease injected into the bearing will not overflow.So far, the bearing filling in one direction has been completed.
