The friction and wear experiment was carried out with the rubber material of a water lubricated alloy bearing and the stainless steel journal material as friction pairs.The rubber alloy material sample are tested in four kinds of lubricating conditions,the dry friction,pure water,sea water and sand water lubrication and at the speed of 01 m/s and 1 m/s,the pressure of 276 kPa and 100 kPa.SEM were applied to observed the surface topography of the rubber alloy material,and the wear performance of the rubber alloy material in different lubricating mediums was investigated.Results indicate that the rubber alloy material has a lower wear rate and a good antiwear performance at different load.there is a big difference of friction and wear condition of the rubber alloy material in different lubricating mediums.The rubber alloy material has the best friction and wear performance in the sea water medium,and the worst performance in the pure water.
