The biggest advantage between the XC air expansion differential shaft and the air expansion shaft is that it can be wound and unwounded very neatly, but its cost is also very high. The expensive cost is that many companies have given up on its application. The maintenance of the differential shaft is even more annoying, because basically the differential shaft companies that are used now are imported machines, and there are no corresponding accessories in China, or it is also because the technology and other aspects are not mature. There are also many problems that lead to failure to repair the differential shaft.

But in our continuous research and development, coupled with continuous accumulation of experience, we can now produce differential shafts ourselves, so in terms of maintenance, we can basically serve all customers. Most of the reasons why the differential shaft needs to be repaired are that the leakage of the differential shaft cannot be used normally due to the problem of the sealing device, so it needs to be disassembled and reassembled. Some worn parts need to be reconfigured, and the sealing ring and other devices are basically the above is all replaced.

But at the same time, we also use airbags for some XC air expansion differential shafts, which are called flat airbags for differential shafts. This kind of differential shaft is more convenient to maintain.
