Abstract

A linear guide device has a guide rail extending in a guiding direction, a guide carriage guided on the guide rail by at least one roll body revolving mechanism in the guiding direction. The at least one roll body revolving mechanism includes a revolving passage and a plurality of roll bodies which revolve in the revolving passage. The revolving passage has a running passage which is limited by a roll body running path formed on the guide rail and by a load-receiving wall portion of the guide car a return passage, and two deviating passages which connect the running passage with the return passage and in which the roll bodies are substantially load free. The guide carriage has a base unit and at least one revolving component group, the revolving component group having at least one lower wall portion of a wall which limits the return passage and at least one lower wall portion of a wall which limits the deviating passages. The revolving component group also has a load-receiving wall portion of the running passage, and holding mechanism which hold roll bodies arranged in a region of the running passage also on the guide carriage.
