Abstract
A method of manufacturing a bearing material, a bearing material and a bearing having the bearing material on a strong backing are described. The method includes the steps of forming a water-based slurry having a solids content comprising 30 to 80% by volume of a fluoro-polymer, 5 to 30% by volume of web-forming fibrillated fibers, and 5 to 40% by volume of filler material selected from at least one of the group comprising: inorganic fibers; inorganic particulate material; metal fibers; metal powders; organic fibers; organic particulate material; and, organic matrix strengthening agents, the web-forming and filler materials being resistant to temperatures above the melting point or curing temperature of the fluoro-polymer; depositing a layer of the slurry on to a substrate so that the water drains from the layer and a deposited layer is formed in which the web-forming fibers form a web containing the fluoro-polymer and the filler material; and, heating the deposited layer to a temperature above the melting point of the fluoro-polymer in order to cure the fluoro-polymer.
