The invention relates to a thrust support combined bearing, in particular to a thrust support combined bearing for a high-rotating-speed unit. The invention aims to solve the problem that safe and stable operation of a unit cannot be better ensured due to the fact that the phenomenon of bearing instability easily occurs in the operation process of an existing high-rotating-speed unit. A plurality of supporting pads are annularly arranged and are connected with a first oil retainer and a second oil retainer, a bearing bush body annularly sleeves the plurality of supporting pads, and supporting points of the supporting pads are respectively positioned at the upper half part and the lower half part of the bearing bush body, which are 45 degrees away from a split; the supporting component is installed in the bearing box support through the auxiliary component. The third oil retainer and the oil seal are mounted on the left side of the bearing bush body, the first mounting ring and the second mounting ring are res
