ABSTRACT:
Nonmetallic bearing compositions contain a polyetherimide resin and, as modifiers and reinforcements, a fluoropolymer, such as polytetrafluoroethylene, a lubricating agent selected from the group consisting of molybdenum disulfide, graphite or a silicone fluid, molybdenum disulfide-containing lubricant or any mixture thereof, and a reinforcing agent selected from the group consisting of glass fibers, carbon fibers and glass beads. The present compositions can be fabricated into a variety of shapes by injection molding, and have excellent wear resistance, load-bearing capabilities, and low coefficients of friction without the use of external lubrication.
