Assembling the linear drive
4.2.2
When assembling a linear drive, wearing parts, such as the sealing band, cover band, seals and the complete piston,
can be replaced.
The wearing parts are ordered on the online spare parts catalogue (spareparts.Festo.com) quoting the appropriate part
number (dependent on the size of the linear drive).
The part number is an x-stroke part number. In addition to the part number, you must also specify the stroke of your
linear drive when ordering. The stroke can be determined from the type code on the name plate of the linear drive
(see order example below). Using this information you can calculate the necessary length or sealing band/cover band.
Cutting the new sealing band/cover band to length
The exact length of the sealing band and cover band is determined by the 0-stroke of the respective type and the stroke
of the linear drive. The stroke is specified by the type code on the name plate. Check the length of the new sealing band
and cover band and shorten them to length (0-hub + hub) as necessary. See order example.

Example: DGC-25-330-G
0-stroke:

Stroke:

Length of the sealing band/cover band =
0- stroke = 580 mm
The length of the band calculated in this way is a theoretical value. Component tolerances may make it necessary to
adjust the length of the sealing band/cover band after installation.
Note
Sturdy general purpose scissors or metal shears are best for cutting the sealing band and cover band.
Warning
Do not bend the sealing band and the cover band as this may cause damage or tearing and reduce the service life of
the sealing band/cover band.
