This invention relates to self-lubricating bearings or other antifriction elements formed of a lubricant-containing polyacetal. It can be manufactured in various shapes by molding a powdery mixture of the polyacetal having a bulk factor of 2-8 with 2-12 wt % of the lubricant which is in a liquid state at a normal room temperature or at the melting point of the polyacetal by a screw type injection molding machine having controlled temperatures in the feed, compression, metering and nozzle sections of the heating cylinders. During the process, the lubricant is uniformly dispersed in said resin material as fine particles independent from each other and this accounts for the extraordinarily high retention of lubricant film which forms on the bearing surface of the molded articles in use.
