A rotary machine includes a shaft (18) extending through the rotary machine; a bearing (72) positioned around the shaft (18); and an air deflector (100) mounted on the shaft (18) between the bearing (72) and the shaft (18), wherein the air deflector (100) has a first cylindrical body portion (110) that is connected to a second cylindrical body portion (114) with a ramp portion (112). A method for cooling a bearing (72) positioned around a rotating shaft (18) includes providing air to a cavity (84) that surrounds a rotating shaft (18); deflecting the air towards an inner surface of a bearing (72) that is positioned radially outward of the rotating shaft (18), wherein the air is deflected with an air deflector (100) that is mounted on the rotating shaft (18); and flowing the air between an outer surface of the air deflector and the inner surface of the bearing (72).
