The present invention ensures that a function for capturing foreign matter can be carried out even if a seal ring thermally expands. In this roller bearing with a filter, a rolling element (13) is incorporated between an outer bearing ring (11) and an inner bearing ring (12), a seal ring (20) covers the opening of at least one end of the bearing space, and a filter (23) covering an oil hole (22) formed in the seal ring (20) captures foreign matter included in lubrication oil. The seal ring (20) is formed from resin, and the filter (23) and the seal ring (20) are integrated through insert molding. The filter (23) and the seal ring (20) are formed from the same material. A lip part (41) formed from a circular member (40), which is separate from the seal ring (20), is in contact with the outer bearing ring (11). An engagement part (21) provided on the inner radial side of the seal ring (20) enters a recessed part provided on the inner bearing ring (12) such that, during thermal expansion of the seal ring (20), the engagement part (21) is engaged so as to enable movement of the seal ring (20) in the radial direction with respect to the inner bearing ring (12). |
