A multi-row rolling-element bearing includes first and second bearing rings and first and second rows of rolling elements therebetween. A cage between the first and second bearing rings has a first annular side part having a plurality of axially extending first bridge elements and a second annular side part having a plurality of axially extending second bridge elements connected to the first bridge elements to form bridges and to form pockets therebetween. At least one rolling element of the first row of rolling elements and at least one rolling element of the second row of rolling elements are located in each of the plurality of pockets.

A cage segment for a rolling bearing, in particular a taper roller bearing, includes: two side plates; at least two bridges connecting the two side plates; a complete rolling element pocket being between each pair of bridges; and an incomplete rolling element pocket formed by regions of the two side plates which project beyond the bridges in a circumferential direction of the cage segment. Two end faces of each side plate are contoured differently, in particular are convex in one case and flat in the other case.

A cage segment defines a single pocket of a multipart rolling-element bearing cage and includes first and second circumferentially spaced side walls connected by first and second end walls. The first and second side walls and the first and second end walls are formed by at least one sheet metal segment connected at at least one joint.

A single-pocket cage segment of a multipart rolling-element bearing cage includes first and second side walls connected by first and second end walls. At least one of the first and second side walls or at least one of the first and second end walls is a semi-finished profile. The semi-finished profile may include a longitudinal channel in which a portion of an auxiliary body and/or a portion of a connector may be inserted.

A three-section synchronous concealed slide rail includes a mobile rail, a middle rail, a fixed rail and a damping mechanism. An upper rack and an upper roller cage with an roller are installed between the mobile rail and the middle rail, a split-type lower roller cage with a roller is installed between the middle rail and the fixed rail, a surface of which is provided with a rack. A gear assembly is meshed between the upper rack and the lower roller cage and used for controlling synchronous or staggered operation of the mobile rail and middle rail according to the intensity of acting force, and the damping mechanism is installed on the fixed rail.
