THE INVESTIGATION OF FRICTIONAL CHARACTERISTICS OF NEW DESIGN PTFE SEALS

In this study a new design PTFE (Polythetrafluoroethylene) radial lip seal was experimentally investigated. The purpose of this work is to compare new design seal with respect to commercial elastomer lip seal regarding their frictional torque and seal life. For this purpose, a test system has been developed. In this test system a cylinder block is placed on four load cells to monitor the frictional torque generated between seal and counter face. Seals were tested for 100000 meter sliding distance at 1m/s, 3 m/s, 5 m/s sliding speeds. At the end of many systematic experiments, the characteristics of new design PTFE seal have been obtained.
