Abstract

PURPOSE: To make machining of a bearing member easy and machine it with high presicion by using a plastic material for the bearing member and pressing it with a forming die to form on it a thrust face on the receiving side, spiral groove, protruding section, etc.
CONSTITUTION: Polyamide resin or the like is formed by injection molding or formed by extrusion to make a cylindrical intermediate product, and it is subjected to press working at temperature that is lower than the melting point of the material but high enough to keep its thermo-plasticity. By using this material thus formed, forming of a thrust receiving face 21 and a spiral groove 3 and embedding of a steel ball 6 that constitutes a pivot sliding face into the member and fixing it with its top protruding by t1 are done easily with high presicion.
