PURPOSE:To increase the pressing force of a press by providing a thrust roller bearing having a hydraulic jack and a plain thrust bearing to support vertically a load of rotary disk. CONSTITUTION:Cylindrical roller bearings 7, 8 are installed between a rotary disk 1 and a frame 4, and a thrust roller bearing 9 is provided to the annular recessed part 12 of disk 1. Further, a thrust plain bearing 11 is provided to the lower part of disk 1 to support a load in the direction of vertical axial-line by the bearings 9 and 11. When pumps P1, P2 are driven by motors M1, M2 respectively, a load of press in its vertical axial-line direction can be loaded on both bearings 9 and 11 at the same time, to increase remarkably a pressing force of press.
