摘要：The invention relates to a rolling bearing, in particular a centreless large rollingbearing, composed of two concentric raceways (1, 2) of which the one raceway (1) has anencircling groove (15) which is open in the direction of the other raceway (2) and theother raceway (2) only has an encircling lug ring (5) which engages with a spacing on allsides 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) onthe one hand and a corresponding surface in the groove (15) on the other hand, and ineach case one row of cylindrical rollers (7, 9) for absorbing axial forces is providedbetween 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) iscomposed of a holding ring (4) and a support ring (3). The invention consists in that aprojection (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 cylindricalrollers (10) is arranged between the projection (12) and the lug ring (5), such that the lugring (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).
