PROBLEM TO BE SOLVED: To provide a rolling bearing device which shortens the time for lubricant running-in operation without causing problems.SOLUTION: A rolling bearing device includes: an inner race 11; an outer race 20; a rolling element 28; a holder 30; and a seal member 40. A cylindrical protruding part 50 which is inserted into an annular space formed between an outer peripheral surface of the inner race 11 and an inner peripheral surface of the holder 30 and inhibits lubricant flow against the annular space is formed at the inner side of the seal member 40. Lubricant passages 35, 39, in which the lubricant may pass from the outer peripheral surface side of the inner race 11 to the inner peripheral surface side of the outer race 20, are formed between the holder 30 and the rolling element 28 or at a part of the holder 30. |
