PTFE AS A JOURNAL BEARING MATERIAL

Abstract

This study investigates the comparative analysis of polytetrafluoroethylene composites that how properties of PTFE can be improved and it is logical to expect that its load- carrying ability and its wear resistance can be improved by the addition of suitable fillers. How the use of both soft and hard phases in a polymer matrix improving the tribological properties of the PTFE is presented. Friction and wear tests of PTFE composite against AISI SS 304 stainless steel are carried out under dry conditions using a pin-on-disc arrangement. PTFE composites includes graphite filled PTFE, bronze filled, carbon filled pure PTFE are tested under tribo-meter steel counter-surface for various load conditions. Bronze filled, carbon filled, and   PTFE are found to be superior properties and less variation over the course of testing and very well suitable as a polymer journal bearing material.
