Nanoparticles with unique properties have been widely used in various fields. The tribological performance of the fabric self-lubricating liner, which is used as the main component of spherical plain bearings, directly affects the bearing service life. The purpose of this study was to prepare a self-lubricating liner enhanced with nano titanium dioxide (nano-TiO2) by dispersion technology. The effects of several factors on the dispersion of nano-TiO2 were studied in detail. The effects of the dispersion of nano-TiO2 on the tribological properties of a self-lubricating liner were analyzed comparatively. The best dispersing conditions were determined through experiments and statistical characterization. From the results of the tribological tests, the fabric self-lubricating liner reinforced with nano-TiO2 showed better antifriction and wear-resistant properties than that without nanoparticles. © 2013 Wiley Periodicals, Inc.
