A linear roller bearing has raceway elements, which are grouped around the central axis of the bearing, include rows of rolling elements distributed around a circle-as viewed in the cross section-and which are essentially parallel to each other and to the central axis of the bearing, the raceway elements being by enclosed in the circumferential direction by at least one connecting piece on at least one longitudinal section such that the raceway elements bear via the outer surface of the longitudinal section against a facing inner surface of the at least one connecting piece. The inner surface and the outer surface are curved biaxially and bear against each other in two dimensions, thereby resulting in a design similar to that of a ball joint.
