Abstract
A guide rail, for use with a guide carriage having at least one row of rolling elements, extends along a longitudinal axis and has at least one running surface for the rolling elements, a separate heat sink, and a plurality of first through holes. The running surface is arranged parallel to the longitudinal axis. The heat sink extends along the longitudinal axis and lies against the guide rail. At least sections of the heat sink delimit a first and a second cooling channel that each extend along the longitudinal axis. The first through holes are distributed along the longitudinal axis and are configured to receive screw-bolts. The heat sink has a plurality of second through holes, each aligning with and continuing an associated first through hole. The first and second cooling channels are located on opposite sides of the plurality of second through holes.
