Abstract:
1. A rolling-element bearing, comprising: a bearing inner ring, a bearing outer ring, a cage disposed between the bearing inner ring and the bearing outer ring, the cage having a plurality of pockets defined therein, and a plurality of rolling elements respectively retained in the pockets and disposed between the bearing inner ring and the bearing outer ring, the rolling elements each having an axial length, wherein the cage further has: a guiding section extending along the axial length of the rolling elements, a distance between a radially-inner surface of the guiding section and a rotational axis of the rolling-element bearing progressively decreasing at least in sections along an axial direction of the rolling-element bearing from a point of the guiding section that is most distant from the rotational axis, a conveying section connecting to the point of the guiding section that is most distant from the rotational axis, the conveying section extending outside the axial length of the rolling elements, wherein a distance between a radially-inner surface of the conveying section and the rotational axis progressively decreases at least in sections in the axial direction away from the rolling elements, at least one lubricant collection channels defined in an axial region between the guiding section and the conveying section and extending at least substantially in a radial direction of the rolling-element bearing, the radial direction being perpendicular to the axial direction, and a plurality of boundary surfaces respectively opposing axial ends of the rolling elements and respectively delimiting the cage pockets at the point of the guiding section that is most distant from the rotational axis.
