  • Patent number: 5743659
    Abstract: A split bearing, a cage for a split or non-split bearing and a method of cutting a member of a split bearing is related in this disclosure. The split bearing has at least one component, such as the outer race, split, i.e., formed into at least two parts, each part defining two longitudinally extending surfaces which mate with a corresponding longitudinal surface of the adjacent part such that the mating surfaces define a helix in their longitudinal extent. The cage of the split or non-split bearing includes two annular parts that in assembly define a plurality of cavities each one adapted to receive a roller member of the bearing. Each of the two annular parts including at least two pieces joined together by a tongue and groove connection. The method of cutting a member of a split bearing involves cutting the member longitudinally such that the cut mating surfaces, define a helix in the longitudinal direction.
