  • Patent number: 7918604
    Abstract: A linear guide comprises a rail with profiled elements on two opposite sides, and a roll unit. The roll unit and the rails can be displaced in relation to each other in the longitudinal direction of the rails. The roll unit comprises at least two rolls which can run on the profiled elements of the opposite sides of the rail. The rolls are mounted on the roll unit by means of prestressed angular ball bearings and can be prestressed in relation to the rails by a pre-determined force.

  • Publication number: 20090263056
    Abstract: The invention relates to a linear guide comprising a rail (100) with profiled elements (101, 102) on two opposite sides, and a roll unit (200). The roll unit (200) and the rails (100) can be displaced in relation to each other in the longitudinal direction of the rails. The roll unit (200) comprises at least two rolls (231, 241) which can run on the profiled elements (101, 102) of the opposite sides of the rail (100). The rolls (231, 241) are mounted on the roll unit (200) by means of prestressed angular ball bearings (236, 246) and can be prestressed in relation to the rails (100) by a pre-determined force. The assembly is play-free even in the event of an increased load due to the prestress in the angular ball bearings (236, 246) and the rolls (231, 241) in relation to the rail (100), ensuring frictionless operation and precise positioning.
