Abstract
A bearing comprises a resin matrix filled with fluoropolymer, graphite, and other discrete particles of an additive material that is attached to a backing material. The specific selection and mix of fillers with the resin matrix provides the desired blend of bearing properties such as wear resistance, fatigue and erosion resistance and low friction whilst maintaining sufficient flexibility for being formed into flanged cylindrical geometries without detriment to the adherence of the lining to the backing. A method for manufacturing a bearing comprises depositing to a backing material a fluid polymer bearing material comprised of a resin matrix filled with fluoropolymer, various fillers, and discrete particles of an additive to form a continuous consolidated bearing material, and curing the lining material to bond the lining material onto the backing material.
