There are provided a duplex bearing device that can reduce the temperature of lubricating oil supplied from a journal bearing to a thrust bearing and thereby can reduce the total amount of oil supplied, and a rotating machine equipped with this. A duplex bearing device 1 is equipped with a tilting pad journal bearing 2 that accepts a radial load of a rotating shaft 4, and a thrust bearing 3 that is provided on an axial end of the journal bearing 2 and accepts an axial load of the rotating shaft 4 via a thrust collar 10 provided on the outer peripheral side of the rotating shaft 4, and has a journal bearing oil supply path 17 that supplies the lubricating oil from the outside into between journal pads 5 of the journal bearing 1, a thrust bearing oil supply path 20 that supplies the lubricating oil from the outside to the thrust bearing 3, and a re-used oil supply path 23 that supplies the lubricating oil to the thrust bearing 3 only from between the journal pads 5 of the journal bearing 2. |
