  • Patent number: 10371213
    Abstract: A tolerance ring comprising a metallic band for spring features and a complementary low friction material for frictional considerations is disclosed. The tolerance ring is designed to operate within a precisely controlled torque or axial force band to provide a defined amount of resistance and sliding force control between components that move relative to each other. Isolated portions of the tolerance ring form regions of contact with adjacent ones of the components. Other surfaces of the tolerance ring comprise portions with spring features that have geometry suitable for their spring rate, rather than conforming to mating surfaces of the adjacent components.
    Type: Grant

  • Patent number: 8944690
    Abstract: A method of forming a corrosion resistant bushing includes bonding a sliding layer to a first surface of a load bearing substrate to form a laminate sheet and cutting a blank from the laminate sheet. The laminate sheet includes an exposed surface corresponding to a second surface of the load bearing substrate. The blank includes cut edges having a load bearing substrate portion. The method further includes forming a semi-finished bushing from the blank, and applying a corrosion resistant coating to the exposed surface and the load bearing substrate portion of the cut edges to form the corrosion resistant bushing.

  • Publication number: 20120240350
    Abstract: A bushing has a body with a cylindrical shape, an axis, and a plurality of dimples formed in the body extending in a radial direction with respect to the axis. The body is electrically conductive. A sliding layer that is electrically non-conductive is formed on at least a portion of the body. A coating that is electrically non-conductive is formed on at least a portion of the body. The bushing has an uninstalled configuration where the bushing is electrically non-conductive, and an installed configuration where the bushing is electrically conductive.
