  • Flanged half-bearing
    Patent number: 9016948
    Abstract: A flanged half-bearing includes at least one substantially semi-annular thrust washer with an internal periphery having lateral lugs and an intermediary stabilization lug projecting from the internal periphery of the thrust washer, and a semi-cylindrical half journal bearing shell having lateral recesses and an intermediary stabilization recess that are recessed into an axial end face of the bearing shell and are respectively connected to the lateral lugs and the stabilization lug of the thrust washer, wherein the stabilization lug has rotational stabilization edges that project substantially perpendicularly from the inner periphery of the thrust washer, and the stabilization recess is configured for axial relative movement of stabilization lug. An engine includes at least one such flanged half-bearing.
