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： A cylindrical roller bearing 41 comprises an inner ring 42, an outer ring 43 having the same axial width as the inner ring 42 and having an insulation layer 43a formed on an outer diameter surface and both end faces thereof, cylindrical rollers 44 arranged between the inner ring 42 and the outer ring 43, a retainer 45 retaining intervals of the cylindrical rollers 44, and a sealing seal 46 as a sealing member having a roughly channel-shaped configuration in cross section projecting from both end faces of the inner ring 42 and the outer ring 43. Thus, a relation between a length L 3 of the roller 44 and an axial width W 3 of the inner ring 42 and the outer ring 43 satisfies L 3 /W 3 ‰§ 0.4, and a relation between a bearing volume V 3 of the cylindrical roller bearing 41 and an internal space capacity C 3 of the cylindrical roller bearing 41 satisfies 0.25 ‰¦C 3 /V 3 ‰¦ 0.55.

摘要： PROBLEM TO BE SOLVED: To provide a single row ball turning bearing capable of smoothly turning a turn table receiving an eccentric load. SOLUTION: A retainer 6 holding a ball in the peripheral direction between raceway surfaces of an inner retainer 6 and an outer ring is divided into eight segments 6a in the peripheral direction, and a length L in the peripheral direction of each pocket 11 of the retainer 6 is set to be larger than a diameter of the ball so that tensile load and compression load are not applied to the retainer 6, the bearing rotates smoothly, and the turn table is turned at stable turn torque even if moment load accompanied with the eccentric load to the turn table acts on the bearing and relative advance delay phenomenon of the ball occurs.
