Abstract
A linear motion device has a first assembly and a second assembly which is linearly movable relative to the first assembly, in which at least one first rolling surface which extends in a longitudinal direction is provided on the first assembly, the first rolling surface being located opposite a second rolling surface provided on the second assembly, and in which a row of rolling elements is located between the first and second rolling surfaces, and in which a return passage that is substantially parallel to the first rolling surface is provided in the first assembly, the return passage being connected at either end via a curved deflection passage to the first rolling surface such that rolling elements are transferred, thereby enabling the rolling elements to circulate endlessly, and in which the first assembly includes at least one deflection assembly that may be installed as a whole, and that includes a single deflection passage, and the return passage is provided directly and completely in a separate first body of the first assembly, and the deflection assembly is fastened to the first body via a single, separate fastening bolt that is installable from one side, the fastening bolt being located in the region of the center of curvature of the assigned, curved deflection passage.
