The tests for sliding characteristic of sintered aluminum with retained oil for sliding bearing were conducted . The sintered aluminum materials blended of silicon with 40wt% weight in maximum were made for experiments. Results obtained are as follows. There was the relation among the oil content, the radial crushing strength and the hardness. There was the limitation of mean grain size and weight fraction of silicon for the higher quantity of oil and the higher mechanical properties. In that condition, the hardness increased with the quantity of retained oil in subsurface of tested rings.
