1. Keep rolling mill bearings lubricated and clean before checking rolling mill bearings, the surface of rolling mill bearings should be cleaned first, and then the peripheral parts of rolling mill bearings should be disassembled. It must be noted here that the oil seal is a very fragile part, so do not over-apply force to the rolling mill bearing during inspection and disassembly, so as not to cause damage to the parts. If the oil seal of the rolling mill bearing and its surrounding parts have shown bad symptoms, please be sure to replace them, so as to avoid the damage of the rolling mill bearing caused by the bad oil seal.
