Abstract:
This bearing roller chain (11) is provided with: two link plates (12) facing each other; a cylindrical bush (17) for connecting the two link plates (12); a cylindrical roller (21) into which the bush (17) is inserted; a plurality of rolling bodies (22); and two annular, movement limiting members (23). The roller (21) extends in an axial direction and has two openings (21b) located on both sides in the axial direction. The plurality of rolling bodies (22) are arranged between the inner peripheral surface of the roller (21) and the outer peripheral surface of the bush (17). The two movement limiting members (23) are respectively inserted in the two openings (21b) of the roller (21) with the bush (17) fitted in place. The two movement limiting members (23) limit the movement of the plurality of rolling bodies (22) in the axial direction. At least one of the outer peripheral surface of the bush (17), the inner peripheral surface of the roller (21), or each of the rolling bodies (22) has a lubricant containing section capable of containing a lubricant. A recess (29) is formed in a part, in a circumferential direction, of the outer peripheral surface of the bush (17). The recess (29) constitutes the lubricant containing section in the outer peripheral surface of the bush (17).
