  • Patent number: 4033646
    Abstract: A journal bearing with two rows of symmetrically inclined rollers on opposite sides of a midplane includes a split cage whose two halves, meeting at that midplane, form crenelations engaging the rollers. The cage is guided along the inner surface of the outer bearing race which is provided with several peripherally spaced radial bores for the admission of lubricant, these bores opening onto a slightly wider inner peripheral groove formed by confronting annular recesses on the adjoining faces of the two cage halves. Burrs surrounding the inner ends of the bores register with the groove and do not interfere with the rotation of the cage.
