Dryer cylinder shaft head wear repair

The shaft head of the dryer cylinder of the paper machine company sometimes has abrasion problems. Under normal circumstances, the company chooses to replace the bearing and will continue to operate, but it may become more and more severe in the subsequent production process, which will cause the naked eye. Visible swing and abnormal noise accompanied by friction. If the machine is shut down for disassembly and inspection, it will be found that the shaft head is severely worn.
