Bearing seat assembly and centrifugal casting machine

The utility model provides a bearing seat assembly and a centrifugal casting machine. The bearing seat assembly comprises a bearing seat, the bearing seat is provided with a containing cavity, the containing cavity comprises a lubricating part, a first connecting part and a second connecting part, the lubricating part is sealed through a first transparent cover and a first sealing ring, the bearing assembly and the shaft end of the rotating shaft are contained in the lubricating part, and lubricating oil filled in the lubricating part can lubricate the bearing assembly. When lubricating oil leaks due to aging of the first sealing ring, the lubricating oil flows into a cavity formed by the first connecting part and the second connecting part from the lubricating part and then flows into an oil receiving cup through an oil outlet channel communicated with the second connecting part. Leakage can be judged by checking whether lubricating oil exists in the oil receiving cup or not. The problem that leakage of lubr
