    摘要： A rolling-element bearing cage includes first and second axially spaced side rings and a plurality of bridges disposed between the first and second side rings. A pair of circumferentially adjacent bridges defines with the first and second axially spaced side rings a receiving pocket configured to receive a rolling element, and each of the plurality of bridges has first and second axially spaced running surfaces. The first and second running surfaces are disposed at first and second axially spaced end regions of the receiving pocket, and a circumferentially recessed region is disposed between the end regions such that a rolling element in a receiving pocket does not contact the recessed region.

    摘要： A cage for a roller bearing having a bearing axis extending in an axial direction, the cage including at least two crosspieces which extend between two axially spaced edges and are spaced from one another in a circumferential direction oriented perpendicular to the axial direction so that a rolling element can be disposed between them. At least one crosspiece of the at least two crosspieces has a first surface region that is a constant radial distance from the bearing axis, and the at least one crosspiece has a second surface region which is adjacent to the first surface region and includes a step along which the radial distance from the bearing axis varies.

    摘要： A bearing assembly includes a first bearing comprising a first inner ring and a second bearing comprising a second inner ring. A sleeve-shaped spacer is disposed between and axially separates the first and second inner rings. The spacer has at least one at least partially circumferentially-extending cantilever arm extending from at least one axial end of the spacer and is configured to at least partially overlap one of the first and second inner rings in the axial direction. The cantilever arms may be annular-shaped and may engage the respective first and second inner rings in a location fit or an interference fit.
