Bearing and bearing assembly

A bearing assembly comprising

• a) thrust bearings comprising an inboard bearing and an outboard bearing each comprising a first-active side in alignment with a radial axis and a second-inactive side opposite said first side, said first side including bumper means for withstanding thrust, extending outwardly therefrom comprising a substantially flat surface, and an inner-axial surface in alignment with an axial axis and an outer-axial surface opposite said inner-axial surface;
• b) means for aligning said thrust bearings in proximity to a rotating device
• wherein said bearing comprises a thermoplastic, amideimide resinous material comprising at least one recurring unit of the following moieties:
• ##STR5## wherein one carbonyl group is meta to and one carbonyl group is para to each amide group and wherein Z is a trivalent benzene ring or lower alkyl-substituted trivalent benzene ring, R comprises one or more wholly- or largely-aromatic hydrocarbon radicals of from 6 to about 10 carbon atoms or two divalent aromatic hydrocarbon radicals of from 6 to about 10 atoms joined directly or by stable linkages selected from the group consisting of --O--, methylene, --CO--, SO.sub.2 --, and --S--.
