    摘要： A bearing assembly including an IC tag in which information can be reliably exchanged between the IC tag and an external reader/writer. The bearing assembly includes a rolling bearing (10) including an outer race (1), an inner race (2) and rolling elements (3) disposed between the outer race (1) and the inner race (2), and an IC tag (20) capable of communicating with an external reader/writer device without contacting the reader/writer device, and attached to a metal member (M) of the rolling bearing. The IC tag (20) includes a tag antenna (24) and is configured such that information can be exchanged between the tag antenna (24) and a reader/writer antenna of the reader/writer device by forming a closed magnetic circuit between the tag antenna (24) and the reader/writer antenna. The IC tag (20) is received in a hole (11) formed in the surface of the metal member (M). The tag antenna (24) includes at least two protrusions (22a and 22c) facing the opening of the hole (11). The protrusions (22a and 22c) are arranged such that magnetic fluxes leaving and/or entering the protrusions (22a and 22c) pass inside of the edge defining the opening of the hole (11) and extend to outside of the hole (11), so that information can be exchanged between the IC tag (20) and the reader/writer device.

    摘要： It is an object of the present invention to more reliably prevent foreign matter from floating in the bearing space of a rolling bearing, while maintaining lubrication performance in the rolling bearing. In order to achieve this object, a rolling bearing is provided which includes an outer race (11), an inner race (12), rolling elements (13) mounted between the outer race (11) and the inner race (12), a seal ring (20) formed with an oil passage hole (22), and covering at least one of the axial end openings of the bearing space of the bearing, a filter (23) mounted to the seal ring (20) so as to cover the oil passage hole (22) of the seal ring (20), and configured to catch foreign matter contained in lubricant oil, and a magnetic member (1) mounted axially inwardly of, and adjacent to, the filter (23), and configured to attract foreign matter to the magnetic member (1) due to the magnetic force of the magnetic member (1).

    摘要： A comb-shaped resin retainer (1) includes an annular section (2) and a plurality of pillar sections (3) which protrude to one side in the axial direction from one side of the annular section (2). A gap between the pillar sections (3), (3) adjacent to each other in the circumferential direction serves as a pocket (Pt) for retaining a cylindrical roller (4). A side face (5) of the pillar section (3) which serves as the inner face of the pocket (Pt) is formed in a recessed shape. Each pillar section (3) is tilted so as to become closer to the retainer axial center as the pillar section (3) extends toward the tip of the pillar section (3). A flat portion (5a) is provided on the side face (5) of the pillar section (3) which serves as the inner face of the pocket (Pt). The flat portion (5a) continues axially from the tip portion of the pillar section (3) to the base end portion thereof.
