Abstract: A rolling bearing retainer (1) for a cylindrical roller bearing is characterized by the fact that a web center part (4.2) is provided with a respective projection (4.3) on a circumferential side, and these projections (4.3), by twisting this web center part (4.2) about its longitudinal axis (4.5), are formed into holding lugs which in each case separate two adjacent cylindrical rollers (6) from one another and prevent the latter from falling out in a radial direction.

Abstract: A cage for cylindrical rolling-contact elements, in which two rolling-contact elements that are in contact with one another at their lateral surfaces are arranged in series in the circumferential direction in a pocket and in which each of the two rolling-contact elements is guided parallel to a cage axis, includes a web connecting adjoining side rings to one another, there being stub-shaped webs on the side rings in the center of the pockets, between the two rolling-contact elements, the webs projecting partially into the pocket between the rolling-contact elements. The webs comprise sections that extend parallel to the cage axis, lie partially inside and partially outside the pitch circle and are connected to one another by sections that extend obliquely to the cage axis. The stub-shaped webs have no contact with the rolling-contact elements during rotation of the cage.

Abstract: The invention relates to a cage (1, 17, 30) for cylindrical rolling-contact elements (8, 9), especially a needle cage, in which two rolling-contact elements (8, 9) that are in contact with one another at their lateral surfaces are arranged in series in the circumferential direction in a pocket (7, 23, 39) and each of the two is guided parallel to a cage axis (1.1, 17.1, 30.1) by a web (6, 22, 33) connecting adjoining side rings (2, 3, 18, 19, 31, 32) to one another, there being stub-shaped webs (15, 29, 40) on the side rings (2, 3, 18, 19, 31, 32) in the center of the pockets, between the two rolling-contact elements (8, 9), said webs projecting partially into the pocket (7, 23, 39), between the rolling-contact elements (8, 9).
