The invention discloses a processing technology of a self-lubricating bearing. The processing technology of the self-lubricating bearing comprises the following steps of S1, placing a bearing and dipping oil, wherein the bearing to be dipped and the dipping oil are placed into a dipping container, the bearing to be dipped and the dipping oil are contained in different containing components correspondingly, and an end cover is locked; S2, conducting vacuumizing and heating on the dipping container, wherein a vacuum pump is started to conduct vacuumizing treatment in the dipping container, and heating treatment is conducted on the dipping container at the same time; and S3, conducting feeding and dipping, wherein in the vacuum state, the bearing to be dipped is placed in the containing component containing the dipping oil to be dipped for 1 h in a temperature-kept manner, after being cooled, the bearing is taken out, and gas is blown in from the bottom of the containing component containing the dipping oil so as to remove bubbles at surface pores of the bearing to be dipped when the step S3 is executed. According to the processing technology of the self-lubricating bearing, the gas for removing the bubbles at the surface pores of the bearing is fed during the processing technology, so that the bubbles hindering the pores of the bearing from dipping into the dipping oil are reduced, and therefore the purpose of improving the dipping effect is achieved.
