Combined insulator and conductor assembly for bearings with adjustable conductor

A bearing assembly comprising:

• a bearing disposable between a shaft and a housing having an inner circumferential surface, the bearing having an inner ring, an outer ring having an outer circumferential surface and opposing first and second axial ends, and a plurality of rolling elements between the rings;
• an annular insulator disposable about the outer ring and configured to prevent electric current flow between the outer ring and the housing, the insulator having a centerline and a plurality of projections extending axially along and spaced circumferentially about the centerline;
• an electrically conductive disk coupled with the insulator so as to be axially adjacent to the bearing, the disk having a centerline, an outer radial end engageable with the housing inner surface, an inner radial end defining a central opening for receiving a portion of the shaft and a plurality of openings spaced circumferentially about the centerline, each opening receiving a separate one of the plurality of projections of the insulator such that the disk is axially displaceable relative to the insulator along the projections;
• and
• an annular conductive brush subassembly coupled with the conductive disk and including a centerline and a plurality of electrically conductive fibers, the conductive fibers being spaced circumferentially about the centerline and extending radially inwardly from the inner end of the conductive disk, each conductive fiber having an inner end contactable with the shaft outer surface so as to provide a conductive path between the shaft and the disk.
