A bearing assembly includes a bearing having a first bearing ring, a second bearing ring rotatably disposed relative to the first bearing ring, and a plurality of rolling elements in a bearing interior defined by the first bearing ring and the second bearing ring. Also, at least one layer of non-metallic material on the first bearing ring configured to conduct heat away from the first bearing ring and to electrically insulate the first bearing ring and to fill at least one cavity between the first bearing ring and a component to which the first bearing ring is mounted. The at least one layer may be a first layer of a heat-conducting material and a second layer of a different, electrically insulating material.
