摘要

The guide wagon (20) has a main body (21) made of metal with a carrying track (22), where a sequence of roller bodies (14) is arranged between the carrying track and the guide rail (12) so that the guide wagon (20) is moved in longitudinal direction against the guide rail. Each carrying track is assigned to a return channel. The return pipe (30) has a compensation part made of metal, which extends over the length of the return pipe. The compensation part has the same or a smaller heat expansion coefficient than the main body.
