ABSTRACT:
A thrust bearing assembly for a hinge structure having two geared hinge members and a clamp member. The geared hinge members are maintained in rotatable, intermeshing relation along their adjacent longitudinally extending edges by the clamp members to permit smooth and uniform movement of the hinge structure. The thrust bearing assembly of the present invention includes a pair of non-metallic interconnected inserts arranged in side-by-side order to extend laterally across and inhibit relative longitudinal movements between the hinge members. The interconnected inserts are configured to facilitate their insertion in and removal from the hinge structure while maintaining the hinge members in mesh.
