ABSTRACT:
The present invention provides a process for making a filled fluoropolymer bearing comprising providing an aqueous fluoropolymer dispersion comprising fluoropolymer particles and anionic polyelectrolyte dispersing agent in an amount sufficient for stabilization. The dispersion contains less than about 300 ppm fluorosurfactant based on the weight of the dispersion. The dispersion is coagulated to make a mush and a bearing filler is added to the dispersion prior to or after making the mush. The mush containing bearing filler is applied onto a bearing substrate to produce a coated substrate which is sintered and formed into a bearing.
