Powder metallurgy bearing is made by pressing, sintering, shaping and oil-immersing metal powder and other anti-friction materials. It has a porous structure. After being soaked in hot oil, the pores are filled with lubricating oil. The journal rotates during operation. The suction effect and friction heating of the metal and oil heat the metal and the oil to squeeze the oil out of the pores, and then the friction surface acts as a lubrication. After the bearing is cooled, the oil is sucked back into the pores. So what are the common problems in the use of powder metallurgy bearings?
