An inner-ring-fastened roller sleeve includes an inner ring and a roller-and-cage assembly. The inner ring is arranged for fastening on a shaft or axle and includes an outer lateral surface with an inner raceway, and first and second flanges extending radially outwards. The second flange includes a larger outer diameter than the first flange and an edge region bent axially towards the first flange. The roller-and-cage assembly is disposed on the inner ring and guided by the first flange and the second flange. The roller-and-cage assembly includes a bearing cage formed as an axially slotted plastic cage and a plurality of roller-type rolling elements inserted into the bearing cage and arranged to roll on the inner raceway. The bearing cage includes a first side ring radially surrounded by the edge region to fix the roller-and-cage assembly in the inner ring, a second side ring, and a plurality of connecting webs.

Inner-ring-fastened roller sleeve and method for producing same

A plastic cage consists of two side rings that have a common axis of rotation and are axially spaced apart from one another, and a plurality of cage webs that connect the side rings to one another and between which pockets are formed for receiving rolling elements, wherein the plastic cage is axially slotted at at least one peripheral location by a parting line which defines a first cage end and a second cage end and at the boundary surfaces of which mutually corresponding closure elements are located, by means of which the first and second cage ends can be fixed relative to one another both in the axial and radial direction and in the peripheral direction.

A segment bearing device for supporting a first bearing partner relative to a second bearing partner about a pivot axis (S) includes a plurality of rolling elements, a segment cage for receiving the rolling elements, and a partial shell, the partial shell providing a race for the rolling elements. At least one of the plurality of rolling elements is arranged as a mounting rolling element in a first partial circle (TK1) in an operating state of the segment bearing device, and is held in a second partial circle (TK2) in a mounted state of the segment bearing device. The common center point of the partial circles (TK1, TK2) is defined by a center of curvature of the segment cage, and the first partial circle (TK1) has a smaller diameter than the second partial circle (TK2).

A rolling bearing cage includes axially spaced side rings, cage webs connecting the side rings, cage pockets, and first and second cage ends. The cage webs have rolling element guides projecting radially inwards and the cage pockets are formed between the rolling element guides. The first cage end has a closing element formed by an axial groove at a radial web surface of a cage web that is reinforced relative to the other cage webs and delimits a penultimate cage pocket. The second cage end has a closing element formed by a partial cage web connecting the end portions at the second cage end to one another. The partial cage web is arranged to hook into the axial groove to form a cage lock that secures the second cage end to the first cage end against unintentional loosening in a peripheral direction and in both radial directions.
