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. 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.

A method for forming a plain bearing, comprising:
- providing a single layer metal substrate;
- leveling the single layer metal substrate to form a backing material;
- preparing a bearing lining material comprising a mixture of approximately 70 to 90% by volume of an epoxide thermoset resin, approximately 5 to 20% by volume of at least one fluoropolymer, and approximately 1 to 8% by volume of at least one other filler;
- depositing the bearing lining material directly onto the single layer metal substrate;
- and
- drying the bearing lining material to bond the bearing lining material directly onto the single layer metal substrate and to form a bearing lining material layer having a constant thickness;
- wherein the bearing lining material deposited directly onto the single layer metal substrate is free of solvent.
