Abstract: This invention relates to self-lubricating bearings or other anti-friction elements formed of a lubricant-containing polyamide. It can be manufactured in various shapes by molding a powdery mixture of the polyamide having a bulk factor of 2 - 5 with 2 - 12 wt % of a lubricant which is in a liquid state at a normal room temperature, are at a temperature between the room temperature and the polyamide melting temperature by the screw type injection or extrusion molding machine having controlled temperatures of the heating cylinders in the feed, the compressions, the metering, and the nozzle sections of the extruder.
