Title: Hybrid composite journal bearing and manufacturing method thereof

Abstract: The object of this invention is to provide a hybrid composite journal bearing which is constructed so that a composite liner is positioned on an inner surface of a metal housing having a circular cross-section, thus preventing a journal from being broken or damaged or seized to the bearing, due to friction between the metal or composite journal and the journal bearing. The hybrid composite journal bearing (210) includes a metal housing (211) which is secured on an outer surface thereof to a bearing system and has a circular cross-section. A composite liner (212) is laminated to an inner surface of the metal housing (211) with a uniform thickness so as to minimize friction between the journal bearing and a journal.
