  "textContent": "A journal shaft (30) for a journal bearing assembly (28) of an aircraft engine includes a shaft body extending along a longitudinal axis (A). The shaft body has a radially outer surface (54) and a radially inner surface (52) radially spaced apart from the longitudinal axis to define an inner cavity (50). An oil pocket (62) is defined in the radially outer surface (54). One or more passages (44) extend through the shaft body from the radially inner surface to the oil pocket to provide fluid communication between the inner cavity and the oil pocket. The oil pocket includes a radially inner base surface and interconnecting transition surfaces extending between the radially inner base surface of the oil pocket and the radially outer surface of the shaft body. The interconnecting transition surfaces form a fluid-dynamically smooth and edgeless transition to the radially outer surface of the journal shaft.",
