<P>PROBLEM TO BE SOLVED: To efficiently manufacture bearings of high quality having excellent sliding characteristic. <P>SOLUTION: This bearing manufacturing device 1 is provided with a pressure container 3 for cold isostatic press, a carrying mechanism 7 having a tray 12 for carrying in/out a washer 5, on which top surface resin powder 4 is arranged, into/from a pressurization forming range 6 inside of the pressure container 3, and a pressure-up pump 9 for raising pressure of a pressure medium filled range 8 inside of the pressure container 3. The pressure container 3 is divided into the pressure medium filled range 8 filled with the pressure medium 10 and the pressurization forming range 6 by an elastic partition film 11. The resin powder 4 on the washer 5 is pressed for solidification by the elastically deformed elastic partition film 11 to form a sliding layer 20. In this bearing manufacturing device 1, a process for sealing the whole of the washer 5 to prevent impregnation of the resin powder 4 with the pressure medium 10 is unnecessary, and the even forming pressure can be applied to the resin powder 4 by isotropic pressurization, and a bearing pad 20 having a sliding layer 20 formed at even forming density can be manufactured efficiently. <P>COPYRIGHT: (C)2003,JPO |
