Abstract
A method of forming a bearing includes adding at least one particulate material to an aqueous dispersion of polytetrafluoroethylene, mixing the constituents to allow the polytetrafluoroethylene to coagulate to form a mush, spreading the mush on to a support, and curing the mush to form a bearing lining layer on the support. The method is characterized in that the partiulate material is in the form of an aqueous colloidal dispersion including small particles and in that the small particles of the particulate material itself cause coagulation of the polytetrafluoroethylene without need for an additional separate coagulant material.
