A ball joint comprises: a ball stud which includes a stud part on one end side connected to a structure and a ball part on the other end side; a housing which oscillatably and rotatably supports the ball part of the ball stud; and a ball sheet disposed between the housing and the ball part. The ball sheet includes a recessed/protruding part formed of at least one of a recessed portion and a protruding portion on a surface facing the housing. The housing includes a fitting part having at least one of a protruding shape and a recessed shape each of which fits to the recessed/protruding part.

A split bearing cage for a rolling-element bearing assembly includes a first bearing cage segment and a second bearing cage segment each having two side ring sections axially spaced apart by a plurality of bridges. Adjacent pairs of the bridges define rolling-element receiving pockets for receiving rolling elements of the rolling-element bearing assembly and for holding the rolling elements spaced apart from each other and for guiding the rolling elements. The first bearing cage segment is connected to the second bearing cage segment via a swivel joint that may be formed of a bolt element on a first end of the first bearing cage segment and an at least partial eyelet on the first end of the second bearing cage segment.

The invention relates to a method of forming a rolling element bearing cage assembly, comprising forming one or more segments, the forming of each segment comprising: forming a supporting frame having a plurality of spaced apart openings; forming a reinforcing frame including a corresponding plurality of openings each for aligning with the openings of the supporting frame; and inserting the reinforcing frame within the supporting frame.

An outer ring (26) for a bearing assembly includes an annular backing member (54) having a body, and an annular race member (50). The body has a first portion defining a radial inner surface (98) and a radial outer surface, and a second portion defining an axially-facing base surface (110) and a radially-facing end surface (118). The annular race member has a radial outer face (58) and a radial inner face, and a first axial end face and a second axial end face (70) that both extend between the radial outer face and the radial inner face. The annular backing member is in press-fit engagement with the annular race member such that the radial outer face of the annular race member engages the radial inner surface of the annular backing member and the second axial end face of the annular race member engages the axially-facing base surface of the annular backing member such that the members are unitized.

A rolling bearing includes a cage constructed by coupling a pair of split members that are split into halves in an axial direction of the rolling bearing. At least one of the split members has an engagement portion that protrudes in the axial direction toward the other one of the split members. The other one of the split members has an engagement groove that extends along the axial direction and houses the engagement portion. The engagement groove has an insertion port through which the engagement portion is inserted in the axial direction. The insertion port is formed at an end of the engagement groove that is closer to the one of the split members. At least one circumferential face of the engagement groove includes a first inclined surface that increases a circumferential width of the insertion port toward the one of the split members.

A tapered roller bearing includes an inner ring, an outer ring, a plurality of tapered rollers, and an annular cage. The cage has a small annular portion, a large annular portion, and a plurality of cage bars that couples the small annular portion and the large annular portion together. The cage is enabled to come into contact with an inner peripheral surface of the outer ring at least on an axially first side so that the contact allows the cage to be positioned in a radial direction. Each of the cage bars has pocket surfaces each of which faces an outer peripheral surface of the corresponding tapered roller, and each pocket surface has a flat surface shape that is straight in a direction from the inner ring toward the outer ring and that is enabled to come into line contact with the corresponding tapered roller.

Provided is a rotation member connecting structure that does not require an operation of connecting a rotation support member and the rotation member to each other and can prevent rattling of the rotation member with respect to a rotation member support member. In the rotation member connecting structure, a rotation support member 10 has a support shaft 20, and a rotation member 30 has a retention part 50. The support shaft 20 has a restriction part 25 that restricts axial movement of the support shaft 20 with respect to the retention part 50 and a sliding part 27 that slides over an inner periphery of the retention part. The rotation support member 10 and the rotation member 30 are made of materials that are not bonded to each other during molding by the resin materials. In the inner periphery of the retention part 50,a portion that closely contacts the sliding part 27 is formed to be continuous in a circumferential direction so that the rotation support member 10 and the rotation member 30 are molded in a connected state.

A length-adjustable steering shaft for a motor vehicle may include a hollow outer shaft with an unround inner cross section, in which an inner shaft is received in a torque-locked and axially movable manner. A profiled sleeve may be arranged between the inner shaft and the outer shaft, and the profiled sleeve may have a fastening portion connected to the inner shaft. The inner shaft may be configured at least in part as a hollow shaft that has an interior that is open towards the end that is inserted into the outer shaft. To reduce the outlay in terms of production and assembly, the fastening portion may extend from the end into the interior of the inner shaft and is connected to an inner surface of the interior.

A carriage slider and rail assembly is disclosed. The assembly may include a linear rail including one or more surfaces that define a channel. The assembly may include a carriage slider sub-assembly. The sub-assembly may include a slider configured to be axially displaceable within the channel of the linear rail. The sub-assembly may include one or more overload protection lobes including a first overload protection lobe positioned adjacent to a first end of the slider and a second overload protection lobe positioned adjacent to a second end of the slider. The sub-assembly may include one or more friction reducing portions. The overload protection lobes may make contact with the channel of the linear rail when an abuse load is applied to provide overload protection. The overload protection lobes may be configured to not make contact with the channel of the linear rail when an abuse load is not applied.

The ball joint includes a metal ball stud which includes a ball section and a resin housing which rotatably supports the ball section of the ball stud. A limiting member configured to limit molding shrinkage of the housing is embedded in the housing at an interval with respect to an equatorial section of the ball section such that the limiting member is positioned to surround at least the equatorial section of the ball section.
