Water lubricated bearings are commonly used equipment in ship and other fields. The friction factors and other parameters of bearing materials have great influence on the performance of Water lubricated bearings. In this paper, a comprehensive bearing test platform was established, the slurry wear test of bearing material was carried out on the MPH corrosion wear tester, and the effects of wear time, sliding speed and load on the friction performance of bearing material were obtained. And then the effects of different additives on the optimization and improvement of the wear resistance and friction coefficient of bearing bushes have been systematically analyzed. The results show that the friction coefficient increases when glass fiber is added into PTFE matrix, but the effect of carbon fiber is not significant. The material composed of PTFE matrix and graphite not only improves the wear resistance, but also reduces the friction coefficient. Rigid additives increase the hardness of PTFE matrix, while soft additives decrease the hardness of PTFE matrix. Almost all kinds of additives can reduce the impact strength of PTFE matrix.
