A linear motion device has a first assembly and a second assembly which is linearly movable relative to the first assembly; a row of rolling elements that may circulate endlessly is located between the first and second assemblies, the first assembly including a rotatable threaded spindle that extends parallel to the longitudinal direction, and that is engaged in a screw-type manner with a threaded nut, the threaded nut being a component of the second assembly; the first assembly also includes an electric motor that is connected to the threaded spindle in a rotationally driving manner, and the rotational axis of which extends parallel to the threaded spindle; the first assembly includes a single-pieced, first body. The threaded spindle and the electric motor are located next to one another in the region of the first body, the electric motor extending along a first longitudinal section of the first body, while a first rolling surface for the rolling elements extends across a second longitudinal section—which differs from the first longitudinal section—of the first body; the threaded spindle extends over the first longitudinal section and at least in sections over the second longitudinal section of the first body, and the rolling elements are capable of circulating endlessly in the first assembly. |
