  • Patent number: 7476032
    Abstract: 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 (16a) 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 (12a) associated with the races (16a) of the running rail (16), the guide rail (12) is provided with a plurality supporting ribs (12a1); and the supporting ribs (12a1) associated with one and the same race (16a) are aligned essentially parallel to the load transmission direction (B) of this race (16a). In addition or alternatively, in a section (12d) 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).

  • Patent number: 7241048
    Abstract: A linear guide device has a guide rail extending in a guiding direction, a guide carriage guided on the guide rail by at least one roll body revolving mechanism in the guiding direction. The at least one roll body revolving mechanism includes a revolving passage and a plurality of roll bodies which revolve in the revolving passage. The revolving passage has a running passage which is limited by a roll body running path formed on the guide rail and by a load-receiving wall portion of the guide car a return passage, and two deviating passages which connect the running passage with the return passage and in which the roll bodies are substantially load free. The guide carriage has a base unit and at least one revolving component group, the revolving component group having at least one lower wall portion of a wall which limits the return passage and at least one lower wall portion of a wall which limits the deviating passages.
