Abstract：The friction performance of Fe-Cu-C oil-bearing was studied by changing the composition ratio of Cu and graphite, and the bearing formula under certain working conditions was obtained. MoS2 was added as solid lubricant to further optimize the formula and improve the friction and wear performance of the bearing. The results show that the limiting PV value of oil-bearing with Fe-22.0Cu-1.5C component is the highest, and the friction coefficient of oil-bearing with Fe-16.0Cu-1.5C component is the lowest. When 2.0％MoS2 is added to Fe-22.0Cu-1.5C oil bearing, the friction performance of the oil bearing can be effectively improved.
