摘要： A rolling bearing includes an inner ring, an outer ring, a plurality of balls, a cage that holds the balls, and a sealing device that is attached to each of opposite sides of the outer ring in an axial direction to prevent foreign matter from entering inside the bearing. A noise-reduction portion that attenuates sound inside the bearing is formed on at least one of a surface of the cage and a bearing inner-side surface of the sealing device.

摘要： A ball bearing includes an inner ring having an outer periphery in which an inner raceway groove is formed, an outer ring having an inner periphery in which an outer raceway groove is formed, a plurality of balls interposed between the inner raceway groove and the outer raceway groove, and an annular cage that holds the balls. The cage includes an annular portion positioned on one side in an axial direction with respect to the balls and a plurality of cage bar portions that extend from the annular portion toward the other side in the axial direction. Each cage bar portion has a guide portion that positions the cage by coming into contact with the inner raceway groove in a non-contact area other than an area in which the corresponding ball is in contact with the inner raceway groove.
