  • Tungsten carbide enhanced bearing
    Patent number: 7828482
    Abstract: A plain bearing has two components, each having a bearing surface; the bearing surfaces being in sliding engagement with each other. The bearing may be a spherical plain bearing having an outer ring that has a concave bearing surface and an inner ring that has a convex bearing surface. One of the bearing surfaces comprises a layer comprising tungsten carbide. One component may have spaced-apart seating surfaces for engaging a moving structure and a generally concave interior that includes an internal rib between the seating surfaces. A spherical plain bearing can be made by providing an outer ring and an inner ring includes an internal rib, and disposing the outer ring around the inner ring with the convex bearing surface engaging the concave bearing surface. The bearing may be used in a swashplate assembly.
