PROBLEM TO BE SOLVED: To prevent seizure on a rotating shaft and extend the life of a product.SOLUTION: Submerged bearings 30A and 30B each comprise a cover case 31 that surrounds an outer peripheral part of a rotating shaft 15, a sliding body arranged inside the cover case 31, and connecting members 45A and 45B arranged inside the cover case 31 so as to extend along an axial direction of the rotating shaft 15. The sliding body comprises a first sliding body 40A and a second sliding body 40B arranged adjacently to the first sliding body 40A along the axial direction of the rotating shaft 15, and they are different in wear resistance and sliding performance from each other. The connecting members 45A and 45B have thermal conductivity, and connect the sliding bodies 40A and 40B and the cover case 31. |
