The invention relates to a rolling bearing, in particular a centreless large rolling bearing, composed of two concentric raceways (1, 2) of which the one raceway (1) has an encircling groove (15) which is open in the direction of the other raceway (2) and the other raceway (2) only has an encircling lug ring (5) which engages with a spacing on all sides into the groove (15), wherein a rolling bearing composed of cylindrical rollers (8) for absorbing radial forces is provided between the lateral surface of the lug ring (5) on the one hand and a corresponding surface in the groove (15) on the other hand, and in each case one row of cylindrical rollers (7, 9) for absorbing axial forces is provided between the end faces of the lug ring (5) and corresponding end faces of the groove (15) on the other hand, and wherein the raceway (1) which contains the groove (15) is composed of a holding ring (4) and a support ring (3). The invention consists in that a projection (12) which extends in the axial direction and which faces toward the raceway (2) is arranged on the support ring (3) and in that an additional rolling bearing with cylindrical rollers (10) is arranged between the projection (12) and the lug ring (5), such that the lug ring (5) is guided in the axial and radial direction by means of precisely two opposite rolling bearings composed of cylindrical rollers (7, 8, 9, 10).
