Abstract: A dual load path spherical bearing (10) comprises a bearing race (12) and a bearing ball (14). The bearing race (12) comprises a bearing race first half (16) and a bearing race second half (22) adapted to interface with the bearing race first half to form a bearing ball cage. The bearing ball (14) is rotatably caged in the bearing ball cage. The bearing ball (14) comprises a bearing ball first half (30), and a bearing ball second half (32) adapted to interface with the bearing ball first half. The bearing race (12) further comprises a bearing race first half (16) having a coupling shaft with an internally and externally threaded half shaft, and a bearing race second half (22) adapted to interface with the bearing race first half (16) to form a bearing ball cage and having a coupling shaft with an internally and externally threaded half shaft.
Abstract: A one-piece, self-aligning bearing is disclosed which includes a cylindrical bearing sleeve of uniform thickness having an outwardly convex hemispherical flange projecting from a first end of the sleeve and arching longitudinally toward an opposite second end of the sleeve, the flange being of uniform wall thickness.
