The cage has a pair of side plates (10, 11) one on either side of the rollers. Each short-roller has a central cylindrical bore (7). A shaft (14) passes axially through each bore (7) with radial play and along a center-line (15) of the short-roller. During operation of the bearing equipped with this cage, part of the ambient lubricant in the axial bore of the short-rollers becomes centrifugally pushed towards the side ends of the short-rollers and from there it is flung radially outwardly towards the outer surface of the adjacent long rollers. In this way there is effected a continuous distribution of flowing lubricating medium environment both to the outer surface of the long rollers and to the guiding surfaces ofthe recesses of the side plates, which closely slide on this outer surface.

The inner ring has spaced apart flanges or lips between which the rollers move. The cage includes an annular ring at the radially smaller side which has undulations circumferentially around that ring. The indulations have axially inwardly directed crests that rest against and are pretensioned to urge the rollers toward the other inner ring flange. The webs of the cage between neighboring rollers have radial projections which engage the flange at the radially smaller side of the bearing. The distance between the plane which passes through the axial end surfaces of those radial projections and the plane which is defined by the tips of the undulation crests against the ends of the rollers is slightly greater than the difference between the distance apart of the flanges and the length of the rollers between the flanges.
