The important design factors for designing solid lubricating of dynamic seal are tightness, wear resistance and lubricant films. In this study, the effect factors influenced solid lubricating properties of the graphite were analyzed and wear behaviour caused for various test conditions was compared with results obtained from reciprocating wear tests. Also the optimal conditions for formation of lubricant films were investigate to evaluate wear properties of graphite materials. The repeated procedure for the formation of wear particles and lubricant films, and the dissipation of lubricant films was estimated the wear mechanisms with changes of wear depth. Therefore the lubricant film of graphite seal was generated by adhesion of wear particles on the worn surface and it was very useful in wear characteristics
