PURPOSE:To provide a high-performance underwater bearing device capable of changing an impact load into a relaxation load when the impact load due to an external force is generated on a bearing section, capable of preventing the damage due to brittleness while exerting the abrasion resistance of ceramic, and having improved reliability and safety. CONSTITUTION:A sleeve 2 coated with ceramic 3 is provided on the outer periphery of a rotary shaft 1. Bearings 4 coated with ceramic on the surface and split in the peripheral direction are arranged on the periphery of the sleeve 2. A spherical recess is machined on the outer periphery of the bearing 4, and this portion is supported by a screw type pivot 5 fixed to a bearing housing 6 by the screw section of the bearing housing 6 and a double nut 7. |
