PROBLEM TO BE SOLVED: To prevent thermal deformation of a thrust runner of a thrust bearing device. SOLUTION: The thrust runner 3 has half ring type separate thrust runners 3a, 3b connected by a clamp bolt 6 and a clamp nut 7 to be a ring shape. On an upper face of the thrust runner 3, a fabricated hole 5 for clamping is formed and a thrust collar of a shaft is stuck. On a lower face of the thrust runner 3, a stationary plate is slidingly contacted. The thrust runner 3 part is immersed in lubricant. A drilled hole 10 to pass through from an inner circumferential side to an outer circumferential side and to go through the fabricated hole 5 for clamping is formed on the thrust runner 3 to fill the lubricant in the fabricated hole 5 for clamping by using the drilled hole 10. Thereby, good cooling can be achieved for preventing thermal deformation to maintain good bearing performance. |
