  • Publication number: 20250043829
    Abstract: An electrically conductive assembly prevents current flow through the raceways of a bearing and includes a conductive base plate having a centerline and including an annular main body with an inner and outer radial ends. One or more mounting lugs extend radially outwardly from the outer radial end of the main body and are connectable with the exterior surface of an outer member to secure the conductive assembly to the outer member at a position spaced axially from the bearing. The main body may be flat and include one or more stiffening flanges extending axially from and at least partially circumferentially about the inner perimeter of the main body and/or the outer perimeter of the main body and/or the outer perimeter of the mounting lugs. Alternatively, the main body is formed as a circular hub having a bore for receiving the conductor and each mounting lug includes two stiffening ribs.

  • Publication number: 20250007348
    Abstract: A method is for assembling an assembly including a brush having a support with a mounting portion and a mounting plate having a main body and tabs, each tab having an axial portion in radial contact with the support. The method includes the steps of: positioning the support against the main body, the mounting portion having, in a free state, an outside diameter; forming the tabs by partially cutting the mounting plate; and assembling the tabs against the mounting portion, the mounting portion having, in the area of the axial portion of each tab, an outside diameter that is lesser than its outside diameter in the free state.
