4.2.4.3 Installing the toothed belt EXCM-30
The toothed belt is ordered from the online spare parts catalogue using the appropriate part number (dependent on the
size and version of the planar surface gantry) (

www.festo.com/spareparts ).
The part number is a module number and is dependent on the size of the planar surface gantry. In addition to the part
number, you must also specify the stroke of your planar surface gantry when ordering. The information required is shown
in the product labelling on the planar surface gantry (see order example below). You can use this information to calculate
the necessary toothed belt length.
Cutting the new toothed belt to length
The exact length of the toothed belt in mm is derived from the total of the zero stroke plus 4 × X stroke plus 2 × Y stroke.
Check the length of the new toothed belt and shorten it, if necessary, to the calculated length with sturdy general
purpose scissors. See order example:
Toothed belt length = Zero stroke ((4 × X stroke) + (2 × Y stroke))
 
Example: EXCM-30-300-210-GF-ST-B-E1
Zero stroke length: 490 mm
X-stroke: 300 mm
Y-stroke: 210 mm
Length of the toothed belt = 2110 mm
Note
Always cut the toothed belt to length between two teeth.
