A rolling bearing comprising: an inner ring, an outer ring, wherein the inner and outer rings are the only two rings, and at least one row of angular contact rollers disposed between raceways provided on the rings, each roller having a rolling surface in contact with the raceways and two opposite end faces, wherein an entire length of the rolling surface of each roller is in contact with the raceways of the inner and outer rings such that the inner and outer rings together provide only two discrete regions of contact on the rolling surface of each roller, a plurality of spacers each disconnected from the rest of the plurality of spacers and disposed circumferentially between the rollers and configured to only contact the rollers along the rolling surface thereof, wherein guiding faces being configured to contact the end faces of the rollers are provided on the inner ring and the outer ring depending on a load exerted on the rolling bearing, a clearance being present between the guiding faces and the end faces of the rollers with respect to the length of the rollers to allow a relative sliding between the end faces of the rollers and the inner and outer rings such that the rolling bearing is capable of operation with each roller in contact with the raceways and only one of the guiding faces, wherein a length of the guiding faces is smaller than a length of the raceways, and wherein each guiding face is connected to a corresponding one of the raceways by a fillet.
