The invention relates to a linear guide for machine elements moving relative to one another, for example a carriage guide for machine tools, said guide containing a machine bed (1) as stationary machine element and a carriage (2) as movable machine element, which is supported by rolling bodies on the tracks in the machine bed (1) in such a way that it can move longitudinally. According to the invention, several axial roller bearings (3) having two rolling rings or rolling discs and a set of rolling bodies located between the latter are arranged in the carriage (2). At least one of said rolling discs culminates in a bushing and is retained in the carriage (2) while the other rolling disc is configured in the shape of a dome and is supported with its convex dome surface on the adjacent surface of the machine bed (1), wherein the central axis of the bushing is offset at an angle relative to the normal line of the surface of the machine bed (1). |
