Abstract: In this paper, the effects of load, velocity of sliding and sliding distance on sliding friction and sliding wear of polymer material made of polytetrafluoroethylene (PTFE) and PTFE composites with filler materials such as 40% bronze and 40% carbon are studied. The experimental work is performed on pin-on-disc apparatus and analyzed with the help of Design-Expert 7 software. The results of experiments are presented in tables and graphs which shows that the addition of bronze and carbon filler to the virgin PTFE decreases wear rate significantly and there is marginal increase in coefficient of friction .The highest wear resistance was found for 40% carbon filled PTFE followed by 40% bronze filled PTFE and virgin PTFE. Through this study, we can design and develop a best bearing material for industrial application.
