Abstract: PROBLEM TO BE SOLVED: To damp vibration with an oil film by enabling a bearing to be lubricated and cooled to generate sufficiently high pressure. SOLUTION: This rolling bearing is for a turbo engine to support a first shaft 4 to rotate to a second shaft 6. It is provided with a plurality of rolling elements 12 engaged between an inner ring 14 and an outer ring 16, the oil film 18 formed as a circular contact surface between the outer ring and the first shaft, a duct 34 passing the inner ring to communicate with an inner race for lubricating them, and an additive duct 38 passing the inner ring to communicate with the outside of the inner race to supply oil to the oil film by effect of centrifugal force by the second shaft that is rotating. The outer ring has a circular shoulder part 42 radially projected toward the inside of a circular space, and the circular shoulder part has a channel 40 positioned to the additive duct to open to be connected to the inside of the oil film.
