A segmented pilot ball is assembled within a spherical bearing for procesg a self lubricating liner. The two-part pilot ball includes a major annularly shaped hollow segment with a smaller cutout portion. A minor segment has the shape of the cutout portion so that when the major and minor segments are assembled, the minor segment complements the major segment to define the spherical outer shape of the pilot ball. An inner plug is shaped to fit within the assembled major and minor segments to provide a compressive force and interior support to the pilot ball within the outer race of the bearing. The bearing is formed by applying uncured liner material to the inner surface of the outer race either before or while rotating the outer race, to evenly distribute the liner and to increase the rate of drying. The outer race is then rotated while heating, in order to reduce liner flow and to form a uniform coating. The major segment is inserted inside the outer race, and is then rotated so that it mates with the outer race. The minor segment is inserted into position for assembly with the major segment, and the plug is then inserted co-axially with the assembled major and minor segments to form the pilot ball. Once the bearing is formed and the outer race is cured, the pilot ball is disassembled and removed.
