Abstract: A linear guide unit with a profiled body, the profiled body having a base plate with an upper side and a bottom side, and a movement unit which has a carriage and which has a guiding unit with a first guiding module located on the carriage and a second guiding module. The movement unit is mounted on the profiled body so as to be linearly movable in the longitudinal direction. A first mounting extension and a second mounting extension project from the bottom side, in which a first support surface of the first mounting extension and a second support surface of the second mounting extension project from the bottom side in a direction opposite to a vertical direction, a first clamping surface being provided on the first mounting extension and a second clamping surface being provided on the second mounting extension.

Abstract: Linear guide having a profiled body extending along an axis of movement and a carriage which is mounted on the profiled body such that it can move linearly along the axis of movement and which has a rolling bearing unit, which bears with at least one rolling element against a guideway. The guideway has two guide rails which are arranged in a row along the axis of movement and which are each positively received on the profiled body in spatial directions aligned transversely to the axis of movement, in which mutually opposite end faces of the two guide rails delimit a joint region and in each case adjacent to the joint region between the respective guide rail and the profiled body a material connection region is formed, which extends at most over 10 percent of a total length of the respective guide rail along the axis of movement.
