PURPOSE:To obtain a ceramic bearing which bears against dry running upon starting, and which has a sufficient durability against water containing therein hard solid substances, by supporting, with the use of a resilient material, each of ceramic pieces which are formed in a segment-like divided shape, along the periphery of each ceramic piece with its slide surface part being set aside. CONSTITUTION:A plurality of ceramic pieces 3a having the radially inner surfaces formed in a curvered surface shape, are laid at equal intervals on the inside surface of a sheet 2 made of hard rubber or PTFE which is adhered to the inner peripheral surface of a housing 1 formed of metals. Further, a filler 4 such as, for example, resin, is filled between the ceramic pieces 3. Further, two end plates 6, 6 are attached to both upper and lower sides of a bearing housing 1 through the intermediary of sheet 5 made of PTFE or the like, by means of bolts 7. |
