<P>PROBLEM TO BE SOLVED: To ensure that a function for capturing foreign matter can be carried out, even if a seal ring thermally expands. <P>SOLUTION: 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 locking part 21 provided on the inner radial side of the seal ring 20 enters a recess provided on the inner bearing ring 12 such that, during thermal expansion thereof, the locking part is locked so as to enable movement of the seal ring in the radial direction with respect to the inner bearing ring 12. <P>COPYRIGHT: (C)2013,JPO&INPIT |
