Abstract
In the present study, Rolling Contact Fatigue (RCF) tests of Poly-phenylene-sulfide (PPS) thrust bearings under dry condition were carried out and the relationship between fatigue life of bearings and temperature was studied. Furthermore, in order to investigate maximum temperature of PPS thrust bearings in service, in order to obtain the calibration data, the temperatures of rolling contact element and Infrared (IR) temperature on the side of top race were measured and correlated. It is concluded that the contact temperature of failure PPS bearing was higher than the glass transition point but lower than a melting point of PPS.
