Abstract
A rolling-element bearing includes inner and outer rings, a cage with pockets disposed therebetween, and rolling elements respectively retained in the pockets. The cage has a guiding section extending along the axial length of the rolling elements. The distance between a radially-inner surface of the guiding section and the rotational axis of the bearing progressively decreases at least in sections along the 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 of the cage connects to that most-distant point and extends outside or away from the axial length of the rolling elements. The 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. A lubricant collection channel is defined between the guiding section and the conveying section.
