The disclosure embraces a self-aligning spherical bearing having two hemispherical rings; each of the rings have inner annular surfaces and substantially planar mating surfaces; one of the mating surfaces is provided with a recess adjacent its inner arcuate edge while the other mating surface is provided with a projecting lip on its inner arcuate edge so that, when the mating surfaces are disposed in abutting relationship, the recess and lip will define a circumferential cavity; a ball member is disposed between the ring members prior to placing the mating surfaces in abutting relationship and then the mating surfaces are fusion-bonded by an energized beam of electrons to form the assembled spherical bearing.
