The research and development process of Polytetrafluoroethylene ( PTFE) oil seal,and research status of its materials and structures at home and abroad were presented. Development trend of PTFE oil seal was prospected. It was pointed out that the overall technical scheme of PTFE oil seal should be started from the aspects of fluid dynamics analy?sis,the structure development of oil seal, the application of lip materials and the test verification of oil seal by bench test, study the key technologies including improving the following of oil lips in high rotational speed,maintaining the lip interfer?ence force of oil seal at high temperature and reducing the wear of seal lip under high linear speed,and ensure that prod?ucts met the requirements of the performance and use life through controlling the lubrication status of oil seal,the lip recov?ery and the toughness on the waist of seal lip.
