ABSTRACT:
Nonmetallic bearing compositions contain a polyetherimide resin and, as a modifier, a fluoropolymer, such as polytetrafluoroethylene. 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.
