Assembling the linear drive
When assembling a linear drive, wearing parts such as the sealing band, cover strip, magnetic strip, 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).
Note
Do not bend the sealing band as this may damage or tear it and reduce its service life.
When replacing the piston module, ensure that the blanking plugs are
mounted in the connection.
