Wash the SKF bearing in gasoline to wipe off the sludge and dust remaining on the bearing. All rusty spherical roller bearings are gently polished with metallographic sandpaper until there is no roughness in the hand. Wipe the cleaned bearing with a dry rag, and then soak it in anti-rust oil. In this process, the spherical roller bearing should be completely in contact with the anti-rust oil, and the bearing should be rotated continuously, so that the oil film formed by the anti-rust oil can cover the surface of the bearing to achieve the purpose of anti-rust. Next, use lithium-based grease and apply butter evenly on the surface of the bearing, including the inner and outer rings, wheels, and cage. And the bearing is rotated while wiping, so that the butter really enters the inside of the spherical roller bearing, and it has a full lubrication effect. In order to save costs, we "turn waste into treasure", cut the discarded cement packaging bags from the warehouse into suitable size packaging bags, wrap the bearings tightly, and mark the specifications and models of the bearings and put them back on the shelf for storage.

The cleaning of the bearing is divided into rough cleaning and fine cleaning. In the container, a metal mesh is placed on the bottom to prevent the spherical roller bearing from directly contacting the stolen goods in the container. For rough washing, use a brush in oil to remove grease or adhesions. At this time, if the spherical roller bearing is rotated in oil, take care to prevent damage to the rolling surface of the bearing caused by foreign objects. During the fine washing, slowly rotate the bearing in oil, and carefully clean the bearing while rotating it. After cleaning, immediately apply anti-rust oil or anti-rust grease on the bearing.
