It is recommended to use Sore carbon nanopolymer material technology to quickly solve the problem of wear on the zipper head wheel axle online. This material is a high-tech nano new material generated through polymerization processes from advanced materials such as aviation grade resins, nano inorganic materials, high-performance carbon materials, fibers, etc. It can be applied in fields such as aerospace, equipment remanufacturing, and industrial maintenance. The biggest advantages of this material are high bonding strength, good comprehensive mechanical properties, corrosion resistance, easy forming, and processability. This technology is not an emergency response technology. Sore carbon nanopolymer materials and targeted repair processes can achieve a 100% matching surface between the repair surface and the bearing interior, while restoring the original interference size of the shaft design, thus ensuring better stress. With proper lubrication and maintenance of the bearing and no burning, its service life can reach or even exceed the service life of new components.
