The specifications/instructions in the relevant
documentation supplied with the product must be
observed.
Commissioning and operation
Make sure that:
ć nobody can place his/her hand between the
slides and that
ć there are no objects within the positioning
range of the DGC−... (e.g. by means of a
protective screen).
Follow the operating instructions for the linear
drive type DGC−...

type DGC−...−FA−...
1 Function and application
The slides of the guide axis support a moving load. When
the load is shifted along the direction of the axis (x), the
slides follow very smoothly. Additional slides on the guide
axis enable loading with higher torques. Shock absorbers
or rubber buffers reduce the impact of the slides striking
against the end positions.
The DGC−...−FA−.. has been designed for setting up boom
or portal systems and consists of a driving linear axis type
DGC−... and a passive guide axis in a horizontal position.
2 Transport and storage
Please note . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
Avoid touching the guide rail with your hands during
transport und storage.
Otherwise you will damage the layer of grease.
· Take into account the weight of the DGC−...−FA−... .
Depending on the design the DGC−...−FA−... can weigh
more than 150Ăkg.
3 Conditions of use
Please note . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
Malfunctions will occur if the device is not used
correctly.
· Ensure that the specifications in this chapter are
always observed.
· Note the warnings and instructions on the product
and in the relevant operating instructions.
· Compare the maximum values specified in these operĆ
ating instructions with your actual application (e.g.
forces, torques, temperatures, masses).
The product can only be operated in accordance with
the relevant safety guidelines if the maximum loading
limits are observed.
· Take into consideration the ambient conditions at the
location of use.
Corrosive elements in the environment (eg. ozone) will
reduce the service life of the product.
· Please comply with national and local safety laws and
regulations.
· Use the product in its original state. Unauthorised
modification is not permitted.
· Remove all transport packing such as foils, caps,
cardboard.
It is intended that the packaging be recycled on the
basis of its constituent materials (exception: oiled
paper = other waste).
4 Mechanical installation
· Compare stroke h of your DGC−...−FA−... with the
assigned drive axis (see type plate specification,
strokeĂLā: DGC−40−800−...).
Stroke length h between the mechanical end positions
can be ascertained in each case from the paths
between the outer edge of the slide system up to the
end position stop.
· Place the DGC−...−FA−... horizontally on a flat surface
(smoothness of surface 0.2 mm). Profile and foot fastenĆ
ings can be used here. The following diagram shows the
distances between the supports with regard to rated size
and loading.
In this way you can avoid stressing the device with
impairment of functioning and service life.

· Fasten the profile/foot fastenings on the DGC−...−FA−...
as shown in the diagram below.
If the DGC−...−FA−... is used in conjunction with a drive axis
type DGC−...ā:
· Use the same distance between the supports of the
drive axis also for the DGC−...−FA−...
In this way you can avoid stressing due to unequal
sagging.
Fitting the fastening elements
Please note . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
· Make sure that the profile fastenings are outside the
positioning range of the slide.
· Position the DGC−...−FA−... exactly parallel to the
linear drive axis.
· Make sure that the cushioning applies preferably on
the load axis and that if both axes are cushioned
then the cushioning must match.
In the case of variants with enlarged surface due to
additional slides:
· Make sure that cushioning elements have been placed
in both end positions (example: shock absorbers on
both axes).

· Make sure that the slide surfaces of both axes lie at
the same level within the complete positioning
stroke.
· Place the lateral connection and the work load as
follows on the slides of the DGC−... and drive axis:
ć Only loadings within the framework of the permitted
values are effective.
ć The tilting torque of force F parallel to the cylinder
axis and distance d remains low.

In the case of guide axes with several slides
· Compare the distance between both slides with the
minimum distance a min of 20 mm.
Only if the minimum distance is observed will you have
access to the lubricating holes for servicing with the
angled tubing of the recommended grease gun.

· Push the lateral connection over the complete stroke
path from one end position to the other. The guide axis
will then position itself free of distortion to the drive
axis.
· Tighten the fastening screws of the guide axis.

· The DGC−...−FA−... will be damaged if it is operated
without the stop sleeve (H) and the locking nut (K).
· Fit the shock absorbers (or the pneumatic cushioĆ
ning) together only with the stop sleeve (H) and the
locking nut (K).
· Observe the maximum distance d and the maximum
tightening torque of the locking nuts of the cushioning
elements.

6 Care and maintenance
Lubricating the guide
· Calculate the loading of guide F
ver with the aid of the
formula for combined loadings (see Technical specificaĆ
tions) and read the lubricating interval S
int from the
diagram below.
· Lubricate the roller bearing through the holes on both
sides of the slide.
For this purpose use a grease gun with pinpoint nozzle.
Permitted types of grease:
DGC−8/12−...−FA−... DGC−18...63−...−FA−...
LUB−LG0 LUB−RN2
· Only if the slide is lubricated and shifted by hand at the
same time will the cavities of the roller guide be filled
with grease to the same extent.
