Assembling the linear drive
When assembling the linear drive, wearing parts such as the sealing band, cover strip, seals, covers, as well as the piston
module and the end cap 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).
Lubricating during assembly
1. Clean the cylinder barrel and all components, see
Chapter 5 “Cleaning”
.
2. Grease the following components as described.
Note
Do not bend the sealing band as this may damage or tear it and reduce its service life.

Further information on the lubricant is included in the information brochure
“Accessories, equipment and tools”
.
This can be found in the online spare parts catalogue on the Festo website (

).
1. Snap both diverters into the piston.
Note
When pushing the piston onto the piston body, ensure that they do not tilt.
2. Push the piston onto the piston body.
Some force is required to push the piston onto the piston body because
the two components are positioned in relation to each other with clamping
sleeves.
3. Screw in the socket head screws and tighten them with a tightening torque
of 9 Nm.
