A segmental bearing device includes a plurality of rolling elements, a segmental cage for receiving the plurality of rolling elements, and a partial shell. The segmental cage has a first end region and a first interference region disposed in the first end region. The partial shell has a bearing race for the plurality of rolling elements, and first and second axial guide flanges for axially guiding the segmental cage. The first interference region lies against the first axial guide flange, axially clamping the segmental cage. The segmental cage may also include a second end region, axially opposite the first end region, and a second interference region disposed in the second end region. The second interference region lies against the second axial guide flange, axially clamping the segmental cage.

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 radial needle rolling bearing, which has a thin-walled outer sleeve with radial rims that are axially inwardly directed on both sides, a plurality of needle bearings rolling on the inner lateral area of the sleeve and on the outer lateral area of the shaft to be supported, and a cage guiding the bearing needles in the circumferential direction in an evenly spaced manner. At least on one side, in addition to the needle cage, an additional stop disc is inserted into the needle sleeve. The disc is delimits axial movability of the needle cage together with a radial rim or a further stop disc inserted into the sleeve. Between the stop disc and the other radial rim, a sealing element is arranged, which seals the bearing. The sealing element is a labyrinth seal, which can be assembled from two individual mutually engaging sealing rings that have complimentary profile cross-sections.

A sealed, single row angular contact ball bearing which has a seal arranged at both axial ends in a region of the rims. One bearing ring has on both sides one receiving opening for the sealing lip carrier and the associated other bearing ring has on both sides one sealing face for the sealing lip. The rims are coordinated with one another in such a way that receiving openings and sealing faces lie in one plane at the same radial spacing from a bearing axis. It is ensured in this way that the same seal can be used for sealing the angular contact ball bearing of generic configuration on both sides.

A radial roller bearing, in particular a single-track ball roller bearing, which has an outer bearing ring with an inner groove track, an inner bearing ring with an outer groove track and ball rollers, which are disposed parallel to one another and held in a peripheral direction at even distances from one another by a plastic bearing cage, that roll between the bearing rings in the groove tracks. Each roller has two lateral surfaces that are flattened symmetrically from a spherical base form and a defined axial tilting clearance. The cage has two axially separated, pocketed cage halves which can be assembled in a positive-fitted, form-locked or integral fashion by opposing connecting elements.

A universal joint bush for a universal joint of a universal joint shaft. In order to seal an annular gap, which is produced between the journal and the universal joint bush, a sealing ring is provided which encloses radially outwardly directed sealing lips. During assembly of the universal joint bush on the journal, the sealing lips, which are connected directly or indirectly to a radially inwardly directed rim of the universal joint bush, make a venting means possible, through which the air which is enclosed in the inner space of the universal joint bush can escape.

The invention relates to a gasket unit () for a journal bearing (), sealing an annular gap () between the bearing bushing () and the journal (). The gasket unit () comprises a main seal () provided with a front seal () arranged in front if it, and a spring washer () is inserted between the rollers () and the primary seal ().
