| Abstract: | The authors give the results of an investigation of full-scale slide bearings made of material based on PTFE in vacuum under conditions which are realized in ordinary engineering. They show that unfilled PTFE possesses insufficient wear resistance, and that very hard mineral fillers cause a marked rise in the coefficient of friction owing to frictional heating.Institute of Polymer Mechanics, Academy of Sciences of the Latvian SSR, Riga.
