Abstract:
1. A linear motion device, comprising a first assembly provided with at least two first rolling surfaces that extend in a longitudinal direction, and a second assembly that is linearly movable relative to the first assembly and provided with second rolling surfaces, where respective ones of the second rolling surfaces correspond to and are located opposite each respective one of the at least two first rolling surfaces provided on the first assembly, wherein a row of rolling elements is located between the first and second rolling surfaces, wherein the first assembly includes a single-piece, first body and at least one deflection assembly, at least one return passage is provided in the first body, at least one curved deflection passage is located entirely within the deflection assembly and connects the first rolling surface to the return passage in a manner such that the rolling elements circulate endlessly, and at least one projection that engages in the return passage is provided on the deflection assembly, wherein the at least one projection is formed by a flexible tube that limits a flexible passage for the rolling elements, which flexible passage connects the deflection passage to the return passage, and wherein the flexible tube is located in a recess in the deflection assembly, the deflection assembly bearing directly against a first body.
