ABSTRACT:
A heat-resistant, lubricative resin composition which is low in friction and wear-resistant, and which is less likely to attack a soft alloy such as aluminum alloy, and a heat-resistant sliding bearing formed from such resin composition. Such heat-resistant, lubricative resin composition, adapted to be brought into sliding contact with a mating member made of an aluminum alloy, may be composed of 35-74% by weight of at least one heat-resistant thermoplastic resin selected from the group consisting of polyphenylene sulfide resins, thermoplastic polyimide resins having predetermined repeating units, polyether ketone resins, polycyanoarylether resins, polyamide-imide resins, polyether imide resins, polyether sulfonic resins, 10-45% by weight of a tetrafluoroethylene resin, and 16-30% by weight of lithium phosphate. Also, the resin composition may be made up of 35-80% by weight of the abovementioned heat-resistant thermoplastic resin, 10-45% by weight of a tetrafluoroethylene resin, 8-30% by weight of lithium phosphate, and 2-20% by weight of aromatic polyamide fiber. A heat-resistant sliding bearing may be formed from either of the above resin compositions.
