  • Patent number: 9869349
    Abstract: A plain bearing bushing is formed from a material strip, wherein a first joining end of the material strip has a projection and a second joining end has a recess interacting with the projection, a base side of the projection being oriented towards the first joining end. A bushing is to be provided that is designed to be more advantageous with respect to the production method, in particular during the forming process, and with respect to dimensional tolerance and long-term stability. This is achieved by a bushing with clamping elements in which the joining ends of the material strip are fixed both in axial direction and in circumferential direction of the bushing in a frictionally engaged and/or formfitting manner.
    Type: Grant

  • Patent number: 9279454
    Abstract: A slide bearing has a layered structure which is substantially uniform over the circumference thereof and comprises a base (10), a lead-free slide layer (12) having a thickness which is reduced in edge zones (16) as compared to a central zone between the edge zones (16), and a polymer coating (14) which is thicker in the edge zones (16) as compared to the central zone, so that the surface level of the coating (14) is substantially flat as seen in axial cross-section.
