Self-lubricating sintered bearings are manufactured by powder metallurgy technology. A metal powder mixture is pressed in a rigid mould with the negative shape of the part, and the resulting compact is sintered in a furnace at a temperature below the melting point of the base metal. The result is a porous metal component with a strong and stable structure. The sintered component is sized to reach a suitable level of dimensional precision in diameter, and as a final step the porosity is impregnated with a lubricating oil.

Self-lubricated sintered bushings admit complementary machining and deburring operations, taking care to avoid machining the inner diameter of the bearing to ensure that the porosity remains open and the lubricating oil can escape from the inside of the bearing and lubricate the shaft-bearing system.

They can also be attached to other components by nailing or overmolding.
