An air cycle machine (100) is provided including a plurality of components operably coupled via a shaft (112), the shaft being rotatable about an axis (X). A cooling airflow path (150) 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 (160) 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.
