An apparatus for fabricating a bearing device comprising a housing having an opening therethrough, a ball-shaped swivel member positioned within the opening and spaced from the surface of the housing which defines the opening, and a raceway of solidified bearing material in the space between the swivel member and housing, the raceway having a swiveling clearance with and retaining said swivel member in the housing, the inner surface of the raceway being shaped to correspond to a part of an elongated sphere. In the fabrication of this bearing device, the swivel member is reciprocated relative to the housing during the hardening of liquefied bearing material injected into the space between the swivel member and housing. The apparatus which accomplishes this method includes relatively movable members which engage, respectively, the housing and the swivel member, these mold members providing the relative reciprocatory movement.
