It includes a guide rail, which has a light-metal main body and at least one guide element, which is connected to the light-metal main body and has a guide surface. A slide for accommodating at least one object and a bearing, which interacts with the guide element and supports the slide on the guide rail in such a way that the slide can move linearly is also included. The guide rail has at least one magnetic fastening means, which makes it possible to temporarily fasten the guide rail by magnetic clamping, in particular in order to process the guide surface.
