A track assembly hinge joint for a track of an endless track vehicle, in which track links are connected by a pin and bushing, is formed by securing the ends of the pin in bores in the ends of a pair of spaced link members and securing the bushing in the inner portions of bushing and pin accommodating bores in the ends of the adjoining pair of link members, with a self-lubricating bearing sleeve disposed between the bushing and the pin and with a self-lubricating washer disposed between each end of the bushing and a side thrust control ring on which a radially inner element of a two-element lip type seal is mounted for cooperation with an outer seal element which is seated in the outer end portion of the bore in the associated link member adjacent the end of the bushing. |
