PURPOSE:To manufacture a bearing having precise dimensions and no biased thickness, by a method wherein raw film made of PTEE fine powder containing a filling attached to an external circumference of a core die in a convering state is sintered by heating and a reinforcement layer made of plastic strengthened by fiber is attached securely on the external circumference of the core die. CONSTITUTION:After putting of a raw film (molded in a cylindrical rod state by pushing, out a mixture of fine powder of PTFE containing a filling and a petroleum system assistant agent by an extruding and made into a thin film by a calender roll, from which the assistant agent is removed by heating) 2 made of the fine powder of lambda polytetrafluorethylene (PTFE) containing the filling (pulverized powder of glass and graphite) on a core metal by wrapping, it is sintered by heating. Then, a composite sliding component is manufactured by pulling the core metal 1 out of a reinforcement layer 5 made of plastic strengthened by fiber after curing of the plastic through heating in the uncured layer 5 wrapped on the external surface of a sintered wrapping after cooling. |
