There is no literature that would present the whole life cycle of a self-lubricating sintered bearing. By examination of an older and newer literature, we gathered the whole procedure from the production of a metal powder to the operation of self-lubricating sintered bearing.
We found out that the main advantage of self-lubricating sintered bearings is a porosity, which allows us not to use an external lubrication. We also found out that it is very hard to describe the conditions between a bearing and a journal; we have to conduct some experiments if we want to understand what happens during the operation of a bearing. For exact description of conditions, we have to know the profile of a surface on a microscale.
