An air cycle machine is provided including a plurality of components operably coupled via a shaft, the shaft being rotatable about an axis. A cooling airflow path receives cooling air from a cooling air source, directs the cooling air to at least one air-cooled bearing associated with one of the plurality of components, and discharges the cooling air. A cooling conduit is arranged in fluid communication with the cooling airflow path, wherein cooling air provided to the cooling conduit from the cooling airflow path has a first temperature and cooling air returned to the cooling airflow path has a second temperature, the second temperature being less than the first temperature.
