The invention relates to a slide for a linear guide which has the slide and a rail element with two running surfaces facing each other. The slide has a main part and a plurality of rolling bodies, and the plurality of rolling bodies are received on the main part such that the plurality of rolling bodies can roll at least on the two running surfaces or carry out a sliding movement relative to the two running surfaces. The main part defines the position of each one of the plurality of rolling bodies in a pull-out direction relative to the main part, wherein the slide additionally has two slide elements and a spring element, and each of the two slide elements is mounted on the main part such that it can move in a vertical direction perpendicular to the pull-out direction so that each of the two slide elements can be brought into frictional engagement with a respective running surface, the spring element being supported on the main part such that the spring element biases the two slide elements away from each other in the vertical direction.

A linear guide device having a guide carriage with two guide units, each guide unit including two guide modules abutting guide surfaces of a base structure in an operating position of the guide carriage. One of the two guide modules is an adjustable guide module, which is adjustable by means of one of two adjustment units to set a pretension between the guide modules and the guide surfaces. For synchronous actuation of the two adjustment units, a central actuating device is provided which is drivingly coupled to both adjustment units.
