N2 - Polyether ether ketone (PEEK) with its high glass transition temperature, low friction coefficient, high heat resistance and good machinability is a promising material to meet the growing demand for lightweight, durable components. In this study, radial PEEK bearings were produced by lathe machining and their rolling contact fatigue behavior under dry condition was investigated. Under low (<80 N) and high (>100 N) radial loads PEEK bearings failed under 5×10 5 cycles by adhesion and seizure, respectively, however under medium loads, the bearings achieved relatively long lives, as well as a unique feature of self-lubrication. An optimum load range to assure the longest possible service life of PEEK components was established.
