Assembling the linear drive
When assembling the linear drive, wearing parts such as the sealing band, seals, covers and the entire piston module can
be replaced.
The wearing parts are ordered from the online spare parts catalogue (
http://spareparts.festo.com
) quoting the
appropriate part number (dependent on the size of the linear drive).
