Abstract: Systems and methods for cooling a bearing may comprise a bearing ring, a rotational member coupled to the bearing ring, a bearing housing coupled to a housing surface of the bearing ring, a first airflow passage through the bearing ring, a cooling entrance pathway, and/or a cooling exit pathway. The bearing housing may comprise a first passage inlet configured to allow a cooling airflow. The first airflow passage may comprise a first passage outlet, may be aligned with the first passage inlet, and may be configured to allow the cooling airflow. The cooling entrance pathway may extend from a first engine airflow channel to the first passage inlet. The cooling exit pathway may extend from the first passage outlet to a second engine airflow channel.

Abstract: A bearing assembly for mounting relative to a housing is provided that includes a bearing ring, a plurality of rotational members, and a bearing ring baffle. The bearing ring has a housing surface, an inner radial surface, a first axial end, a second axial end, and a plurality of channels disposed in the first axial end of the ring. The bearing ring baffle has a housing surface, an inner radial surface, a first axial end, a second axial end, and a plurality of fins extending out from the second axial end of the baffle. The fins and channels are configured to mate with one another and to create at least one passage there between, and the passage is con figured for the passage of lubricant there through.
