The thrust roller bearing cage (11) includes: a radially outer area bent portion (41) formed by bending an area located radially outside the pockets (21) inward in a radial direction; and projecting portions (44) that are formed in a tip end of the radially outer area bent portion (41) at positions aligned with the pockets (21) and project inward in the radial direction beyond radially outer edges of the pockets (21) so as to contact end faces (16) of the rollers (13) accommodated in the pockets (21). The projecting portions (44) have a width that is or more and or less of the width of the pockets (21).

A thrust roller bearing cage (11) a thrust roller bearing (20) and a plurality of pockets (21) accommodating rollers (13). The thrust roller bearing cage (11) includes: a radially outer area bent portion (41) formed by bending an area located radially outside the pockets (21) inward in a radial direction; and projecting portions (44) that are formed in a tip end of the radially outer area bent portion (41) and project inward in the radial direction so as to contact end faces (16) of the rollers (13) accommodated in the pockets. Radially outer edges (21a) of the pockets (21) are located radially outside base end parts (44a) of the projecting portions (44).

A radial support bearing having a cylindrical cage including a central portion, a first end portion and a second end portion, the central portion defining a plurality of roller pockets, and at least one projection extending radially inwardly from an inner surface of the cage, a plurality of rollers, each roller being disposed in a respective roller pocket, a cylindrical outer sleeve disposed about an outer surface of the cage so that the inner surface of the outer sleeve is adjacent the plurality of rollers, and an o-ring adapted to be axially fixed relative to the shaft. The o-ring is slidably received between the at least one projection of the cage and the central portion of the cage so that the cage is axially fixed with respect to the shaft.

Overrunning clutch units are disclosed. In one example, the overrunning clutch unit may include inner and outer rings that can be rotated relative to each other. Clamping members may transmit a torque between the two rings in one peripheral direction, the clamping members being arranged between the rings. A first bearing device may be configured to support the two rings, wherein the first bearing device is arranged between the rings at a first axial side of the clamping members. A second bearing device may be configured to support the two rings, wherein the second bearing device is arranged at a second, opposing, axial side of the clamping members so that a tilting of the inner ring relative to the outer ring is prevented.

In a thrust washer for the axial securing of rolling elements of a bearing, and a gear mechanism including a thrust washer, the thrust washer is arranged as a circular disk, which has an axially protruding, in particular radially outer, projection. The circular disk has a recess, which is disposed out of center, i.e., the center point of the, e.g., circular recess thus particularly being set apart from the center axis and/or from the center point of the circular disk. The projection may have an annular shape, and the ring axis is set apart from the center point of the, e.g., circular recess.

Method for installation in a balancing shaft (12) with at least one bearing (13, 14) having a needle roller and cage assembly (15) rolling on the bearing (13, 14), is assembled with a slotted needle roller and cage assembly (22), which is opened for mounting on the bearing (13, 14) of the balancing shaft (12), and is placed in the radial direction, to engage around the bearing (13, 14), and is closed after engaging around the bearing (13, 14).

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 roller bearing configured to be mounted on a balancing shaft. The rolling bearing having an outer ring, a cage axially protruding beyond at least one side of the outer ring, and rollers mounted in the cage and in rolling contact with the outer ring. The cage provides at least one boss on a side that axially protrudes beyond the outer ring, the boss being dedicated to come into abutment against the outer ring in case of relative axial displacement between the cage and outer ring.

A thrust roller bearing cage (11) is a cage (11) provided to a thrust roller bearing and having a plurality of pockets (21) that house needle rollers (13). The cage (11) includes projections (44) that are formed by bending a radially outer area of the cage (11) inwardly along the radius and that project inwardly along the radius toward a radially outer area of the pockets (21) to make contact with end faces (16) of the rollers (13). The projections (44) have corners (45) that make contact with the end faces (16) of the rollers (13). The corners (45) are press-flattened.

In a bearing device 1 which is assembled to a pinion 3 of a rack-and-pinion type drive mechanism 2, the bearing device 1 has a plurality of needle rollers 13. A plurality of pin rollers 9 are supported by an inner surface cylindrically formed by the plurality of needle rollers 13. Each of the plurality of needle rollers 13 is held at both ends 13a, 13b in an axial direction R by a retainer cage 14, so as to prevent the needle rollers 13 from being skewed against the axial direction R.
