Abstract: In this work, the paper reviews on tribological behaviors of Polytetrafluroethylene (PTFE) composites with filler materials such as reinforced glass fiber, carbon fiber and mos2 under parameters like varying load, sliding distance and sliding speed on pin on disc apparatus. Now a day’s pure PTFE (polytetrafluoroethylene) is widely used as bearing material which is self lubricating and subjects to lower coefficient of friction, but problem with PTFE is that, it subjects to high wear rate, which can be reduced by adding suitable fillers.

Keywords: PTFE, filler materials, pin on disc, PTFE composites.
