Abstract
A rolling bearing assembly with electrical discharge damage protection is provided. The rolling bearing assembly includes radially inner and outer bearing rings that each have a race. A roller assembly including a plurality of rolling elements that are supported to roll on the races is provided. A shield extends radially between the radially outer ring and the radially inner ring. The shield includes a body portion with one radial end that is fixed to one of the radially inner or outer rings, at least one electrically conductive seal on a surface of the body portion, and a plurality of filaments extending on an opposite radial end of the body portion from the fixed radial end that contacts the other of the radially inner or outer rings.
