  • Ball bearing rear inner ring with oil circumferential groove
    Patent number: 11215231
    Abstract: An inner ring for a bearing assembly comprises an inner circumferential surface disposed between a first axial end and a second axial end. A circumferential slot is disposed in the inner circumferential surface adjacent the second axial end. At least one radial passage is disposed within the inner ring and is in fluid communication with the circumferential slot. At least one axial slot extends axially along the inner circumferential surface from a respective opening in the first axial end to the circumferential slot. At least one of the radial passage is circumferentially offset from each at least one axial slot.

  • Bearing assembly with inner rings and method of alignment
    Patent number: 10876578
    Abstract: A bearing alignment assembly comprises an outer ring. An inner ring assembly is disposed radially inwardly of the outer ring and cooperating therewith to form a roller volume. The inner ring assembly has a forward inner ring and an adjacent aft inner ring cooperating to provide an inner surface of the inner ring assembly. The forward inner ring includes axial grooves extending axially along and circumferentially spaced around a forward portion of the inner circumferential surface of the inner ring assembly.
