5 Repair steps
The ELCC-TB-KF-… cantilever axis is made up of the following modules:
– Cylinder barrel with end caps, integrated roller track and optional cover strip, driven by a toothed belt.
– Drive head with toothed belt pulley, drive, slide with recirculating ball bearing guide and optional cover strip guide.
The toothed belt is ordered from the online spare parts catalogue using the appropriate part number (depending on the
size and version of the product) or it is ordered by the metre (5 m roll) (

www.festo.com/spareparts ).
Note
Do not bend or fold the toothed belt, as this can result in damage to the tensile members and shorten its service life
by cracking it. Note the minimum bending radius for assembly and storage:

Ordering a precise fitting toothed belt:
The part number of the cantilever axis is a module number and is dependent on the size of the product. When ordering
the toothed belt, in addition to the part number, the stroke and stroke reserve of the product must also be stated. The
necessary information is given in the order code in the product labelling (
 Chapter 2.4 on page 12 ).
Cutting the toothed belt to size if ordered by the metre
Note
– Use sturdy general-purpose scissors or metal shears to cut through the toothed belt.
– Round down the cut length (L) to an integer multiple of the pitch “C” (

table) to ensure that the belt can always
be cut to size in a gap.
The precise length of the toothed belt is calculated as follows:
L (length of toothed belt in mm) = Multiplier “A” × ( 2 × stroke r value “B”)
Values for multiplier “A” and value “B”
