PROBLEM TO BE SOLVED: To provide a lubricating oil circulation system which reliably supports a rotary shaft of a centrifugal separator rotating at a high speed, assures the smooth and efficient rotation of the rotary shaft, speedily and efficiently carries out periodical inspection of the centrifugal separator or replacement of components, stably feeds a high-quality and excellent lubricating oil to a bearing all the time, prevents the abrasion of the bearing, appropriately and efficiently operates the centrifugal separator, and extends the life of the centrifugal separator itself. SOLUTION: The lubricating oil circulation system includes a rotary shaft supporting device for the centrifugal separator consisting of a base housing, an upper part housing attached to the base housing, the bearing held in a housing box formed of the base housing and the upper part housing, and supporting the rotary shaft of the centrifugal separator with an outer barrel bowl and inner barrel screw, and a lubricating oil feeder arranged in the housing box with a lubricating oil injection nozzle, and feeding the lubricating oil. The system further includes an oil reservoir for storing the lubricating oil, an oil cooler cooling the lubricating oil, and a transfer pump circulating the lubricating oil.
