Abstract

Sliding bearing material containing at least two of aromatic polyester-resin particles, spherical carbon particles, and zinc-oxide whisker dispersed in a matrix consisting of polytetrafluoroethylene. The PTFE-based material exhibits little wear under conditions in which vibration is imparted, thereby enhancing reliability of the sliding parts of various machines and equipment and preventing enlargement of clearances during operation.
