Linear guide unit and method for manufacturing the same

摘要

A guide rail ( 12 ) of a linear guide unit ( 10 ) is provided with at least one running rail ( 16 ), which has at least two races ( 16 a) that have different load transmission directions. According to the present invention, the running rail ( 16 ) is attached to the guide rail ( 12 ) by means of roller insertion; in the surface sections ( 12 a) associated with the races ( 16 a) of the running rail ( 16 ), the guide rail ( 12 ) is provided with a plurality supporting ribs ( 12 a 1 ); and the supporting ribs ( 12 a 1 ) associated with one and the same race ( 16 a) are aligned essentially parallel to the load transmission direction (B) of this race ( 16 a). In addition or alternatively, in a section ( 12 d) that is not intrinsically deformed by the roller insertion of the at least one running rail ( 16 ), the guide rail ( 12 ) has at least one additional rolled section. The present invention also relates to a method for manufacturing guide rails of this kind ( 12 ).
