    摘要： A cage, which is annular, and is used in a thrust roller bearing, includes a plurality of cage segments arranged in a circumferential direction. Each of the cage segments includes an arc portion; and a bar portion that extends radially inward from the arc portion and that maintains a circumferential interval between rollers adjacent to each other. A groove portion extending along an axial direction is formed at each of end faces of the arc portions, the end faces facing each other in the circumferential direction. In the cage, elastic bodies are inserted into the groove portions and urge the arc portions in the circumferential direction, each of the elastic bodies is disposed between the end faces facing each other, and the cage segments are connected to each other by the elastic bodies.

    摘要： A roller element (10) is provided which has a central body (1) and a roller unit (2). The roller unit (2) is mounted so as to circulate on a non-circular race (21) about the central body (1) and so as to be mobile with respect to the central body (1) by the rolling movement of the rollers (3) of the roller unit (2) on the central body (1). The rollers (3) are configured as balls or substantially cylindrical elements. A peripheral surface of the rollers (3), for a substantial part, is shaped as a rolling surface that corresponds to the central body (1) and for rolling off on the central body (1). The elements of the roller unit (2) have play in relation to one another and/or the roller unit has play regarding its mobility in relation to the central body (1).

    摘要： A roller chain adapted to be placed in compression between two members one of which is movable and the other fixed and to bear high pressure arising between these members, comprises a plurality of rollers on each of a series of transverse axles, the axles being interconnected by links of a height less than the external diameter of the rollers. Sleeves are threaded on the axles and the rollers turn on these sleeves. The roller chain is confined between guide surfaces provided on at least one of the relatively moving members between which it is disposed, this member also having removable members thereon that define these guide surfaces, the guide surfaces contacting the outermost links.
