Beschreibung
Zusammenfassung:	A linear guide includes a guide carriage (1) arranged on a guide rail (2) so as to be longitudinally displaceable, and comprising a length measuring device (5) provided on the guide rail (2) for determining a position of the guide carriage (1), which length measuring device has two measuring heads (6) and two tracks (7, 8) arranged side-by-side on the guide rail (2), each of which tracks is assigned to one of the measuring heads (6). Each of said tracks (7, 8) has a plurality of dimensional measures (9, 14) arranged one behind the other along the track (7, 8), wherein in an overlapping region (x1, yn, z1), the dimensional measures (9, 14) of both tracks (7, 8) overlap each other.
