    Abstract: A rolling bearing (3) includes an annular cage (1) formed by two half-cages (9, 10) connected together using connection elements (14). The connection elements (14) include male elements (15), recesses (16) and metal inserts (18, 19). The male elements (15) are carried by a first half-cage (9) and each in the form of a substantially rigid block. The recesses (16) are formed in a second half-cage (10) and receive the male elements (15). First and second annular metal inserts (18, 19) are overmoulded with the first and second half-cages (9, 10) respectively and completely embedded inside respective annular bodies (11) thereof.

    Abstract: The present disclosure provides a bearing cage and a ball bearing. The bearing cage includes an annular backbone portion having a front side and an opposite back side and a plurality of cantilever portions extending from the front side of the backbone portion in an axially forward direction of the bearing cage. The cantilever portions are arranged along a circumference of the annular backbone portion, defining a plurality of pockets. The backbone portion has a radial thickness larger than that of the plurality of cantilever portions. Each of the plurality of cantilever portions includes two prong portions and a connection portion between the two prong portions. The bearing cage further includes one or more of a plurality of recesses formed in a radially outer side of the cantilever portions, and a plurality of grooves formed in the radially inner side of the bearing cage.

    Abstract: A sensor bearing unit includes a bearing, which has a first ring and a second ring, both rings being centered on an axis, and an impulse ring. The impulse ring includes a target holder, a target mounted on the target holder, and a sleeve secured to the first ring of the bearing. The sleeve is provided with an axial portion having at least one radial protrusion and a collar extending at least partially radially. The target holder is mounted radially around the axial portion of the sleeve and axially between the first ring of the bearing and the collar of the sleeve. The at least one radial protrusion of the sleeve axial portion extends into a complementary recess provided on the target holder.

    Abstract: A fitting has a first housing including a first body and a second body. The first body defines a first channel and a second channel, and second body defines a third channel that is co-planar with the first channel and a fourth channel that is co-planar with the first channel. First bearings are disposed within the first channel and the third channel, where the first bearings rotatably coupled the first housing to the second housing. Additionally, second bearings are disposed within the second channel and the fourth channel, the second bearings rotatably coupling the first housing to the second housing. A plug couples to the first housing, a gasket is disposed between the plug and the first housing, and a passage is defined at least in part by the first housing, the second housing, and the plug.

    Abstract: A bearing holding device with an annular inner region and a flange region, extending at least approximately outwards in the radial direction, with recesses, which flange region is designed in one piece with the inner region and is narrower in the axial direction than the annular inner region, is described. The flange region is, in the circumferential region, surrounded at least in certain regions by a connection region, which is formed in one piece with the flange region and via which the inner region and the flange region can be firmly connected to a housing. Furthermore, a rolling bearing apparatus with the bearing holding device is proposed.

    Abstract: A sealed rolling bearing includes slingers and seal members disposed between an inner ring and an outer ring, and sealing a rolling element installation area. The radially inner and outer portions of each slinger are bent axially inwardly such that a labyrinth portion is defined between the radially outer bent portion of the slinger and the radially inner surface of the outer ring, the labyrinth portion having a path length, in the axial direction of the bearing, longer than the material thickness of the slinger.

    Abstract: This application describes a motor that includes a housing, an output shaft, a conductive bearing, and a conductive component. The output shaft is disposed in the housing. A positioning hole is disposed on an end face of a first end of the output shaft, and the positioning hole is disposed coaxially with the output shaft. The conductive bearing is disposed in the positioning hole, and includes an inner ring, and an outer ring that is fixedly connected to the output shaft. One end of the conductive component is fixedly connected to the inner ring of the conductive bearing, and the other end is connected to the housing. In this application, the motor can output, by using the conductive bearing and the conductive component, charges accumulated in the output shaft, to eliminate a generated common-mode voltage.
