1. A bearing assembly comprising:
a rolling element bearing comprising:
an inner ring;an outer ring;a plurality of rolling elements disposed between the inner and outer ring;a bearing seal extending over the radial space between the inner and outer ring and configured to help maintain a lubricant between the inner ring and the outer ring the seal having a lubricant side and an air side, the lubricant side being oriented toward the plurality of rolling elements and configured to contact lubricant, the air side of the seal being oriented away from the plurality of rolling elements and configured not to contact the lubricant between the inner ring and the outer ring, the bearing seal having a radially extending seal segment entirely comprised of metal, wherein the metal extends axially across the radially extending seal segment from the lubricant side to the air side, the bearing seal being press fit into the outer ring and forming a labyrinth seal with one of the inner ring and an adjacent component located thereon; and an acoustic emission unit disposed on the air side of the bearing seal and entirely on the metal of the radially extending seal segment.
