Disclosed is a self-lubricating composite friction part () that can be subjected, during operation, to temperatures that are at least equal to 250&#xb0; C. The part includes, along the friction surface (), a single layer of a material consisting of weft and warp yarns made of polytetrafluoroethylene, the material being impregnated with a thermostable resin having a glass transition temperature that is at least equal to 250&#xb0; C. It is applied to a reinforcing layer ().

This assembly includes a ball joint assembled in a casing, and receiving an axle capable of sliding and/or rotating therein. The ball joint is formed from the winding of a fabric of small thickness ranging between 20 &#x3bc;m and 150 &#x3bc;m and mixed with a resin comprising fillers. The fabric has the form of strips having a width ranging between 5 mm and 200 mm; the strips being crossed in several layers.

This bush is made out of a composite material that has a modulus of elasticity of between 500 and 6000 N/mm2, said bush having at least one lip formed directly at the time of manufacture as an overrun edge of its bore to act as a leak-tight or protective barrier after mounting on the shaft by creating a tightening effect between the inside diameter of said lip or said lips, and the outside diameter of said shaft.
