Zusammenfassung:	A lubricated bearing apparatus for a hydraulic machinery has rotary-side ceramic sliding plates disposed in contact with bearing-side ceramic sliding plates. The rotary-side ceramic sliding plates are disposed in receiving grooves of a main shaft sleeve member fixed to the main shaft. The main shaft sleeve member is provided with preventing portions for preventing the rotary-side ceramics sliding plates from being broken by the centrifugal force. Thus, ceramic materials can be used both on the rotary side and the bearing side, thereby lengthening the usable life of the bearing apparatus.
