A guide carriage for an elongated guide rail includes a main body, an end cap, and at least one row of rolling bodies accommodated in a continuous bypass channel. The end cap bears indirectly against a longitudinal end face of the main body and has a fastening bore through which a fastening screw passes. The fastening screw is screwed into the main body. The continuous bypass channel has a supporting portion and a return channel that are connected via a curved bypass channel that is arranged in the end cap. A lubricant flow path is arranged in the end cap and extends from a lubrication port to the row of rolling bodies. A first cavity is arranged between the fastening bore and the fastening screw. The first cavity forms a component of the lubricant flow path.

A guide carriage is configured for use with an guide rail. The guide carriage has at least one row of rolling bodies received in a circulatory channel. The circulatory channel has a load-bearing section and a return channel connected together at their ends by a deflection channel. The load-bearing section is delimited by a carriage raceway on the guide carriage and a rail raceway on the guide rail. At least one sealing lip is arranged in sealing engagement with the guide rail when the guide carriage is mounted on the guide rail. At least one separate rolling-body guide part, composed in one piece of an elastomer, has two deflection sections, between which at least one guide section, extending longitudinally, is arranged. An associated sealing lip is arranged on the guide section. At least one radially inner deflection surface of a deflection channel is arranged on each deflection section.

A guide rail () of a linear guide unit () is provided with at least one running rail (), which has at least two races () that have different load transmission directions. According to the present invention, the running rail () is attached to the guide rail () by means of roller insertion; in the surface sections () associated with the races () of the running rail (), the guide rail () is provided with a plurality supporting ribs (); and the supporting ribs () associated with one and the same race () are aligned essentially parallel to the load transmission direction (B) of this race (). In addition or alternatively, in a section () that is not intrinsically deformed by the roller insertion of the at least one running rail (), the guide rail () has at least one additional rolled section. The present invention also relates to a method for manufacturing guide rails of this kind ().
