In general, it is fixedly assembled on mechanical equipment through a bearing seat, and the bearing seat is generally composed of an upper shell and a lower shell spliced together by studs. However, in actual use, due to a large amount of flying waste generated during machine tool processing, some waste will fall on the bearing seat. After the bearing has been used for a long time, maintenance is required, so the bearing seat will be disassembled. The waste adhered to the bearing seat may fall in after the studs are disassembled, thus affecting the subsequent assembly effect. Its loading and unloading are relatively cumbersome. At the same time, the bearing is arranged in the bearing seat, and its heat dissipation effect is not good. Summary of the Invention
