2 Function and application
A toothed belt on a drive shaft converts the
rotary movement of a motor into a linear
movement. The slide then moves backwards
and forwards.
The slide is carried by rollers and guide rods
inside the cylinder barrel.
The DGE-...-ZR-RF is intended for the exact
and fast positioning of effective loads.
It is approved for operation in slide mode and
yoke mode (observe loading limits).
The DGE-...-ZR-RF is not permitted for use in
applications in which vegetable water-soluble
fats or oils could penetrate into the axis.
Note
The toothed belt axis DGE-...-ZR-RF is not self-locking: When input torque is not
applied, the slide can be moved freely.
Generally, a latching function of the complete system can be achieved with
motors with an integrated holding brake or other suitable means, such as
clamping systems, motors with high gear ratios or self-locking gears. The choice
of suitable means depends on the application and safety requirements.
SPlease select the appropriate motor from our catalogue
èwww.festo.com/catalogue
You will then be operating two devices which are especially matched to each
other.
STo design the DGE-...-ZR-RF, use the Festo design software “Positioning Drives”
(èwww.festo.com).
SAdhere to the maximum permitted values for forces, torque and speeds
èchapter 12 “Technical data”.

3 Transport and storage
STake into consideration the weight of the DGE-...-ZR-RF.
The DGE-...-ZR-RF weighs up to 120 kg, depending on the design.
SEnsure the following storage conditions:
– short storage times
– cool, dry, shaded storage locations protected from corrosion
– no oils, greases or grease-dissolving fumes.
In this way you can ensure the capability of the toothed belt.

4 Conditions for the safe use of the product
Warning
Unexpected fast-moving masses can cause injury to people or damage to
property (danger of fingers being crushed).
SApply power to the drive motor, at first limited to low speeds and torques.
Note
Malfunctions will occur if the device is not used correctly.
SMake sure that the specifications in this chapter are always observed.
In this way the product will perform as intended.
SCompare the maximum values specified in these operating instructions with
those of your actual application (e.g.forces, torques, temperatures, masses,
speeds).
Operation of the product in compliance with the relevant safety regulations is
contingent on adherence to the load limits.
STake into consideration the ambient conditions at the location of use.
Corrosive elements in the environment (e.g.ozone) will reduce the service life of
the product.
SPlease comply with national and local safety laws and regulations.
SRemove transport packaging such as foils and cardboard.
It is intended that the packaging be recycled on the basis of its constituent
materials (exception: oiled paper = other waste).
SUnauthorised product modification is not permitted.
SNote the warnings and instructions on the product and in the relevant
operating instructions.
STake the tolerance of the tightening torques into account. Unless specified
otherwise, the tolerance is ±20 %.

5 Installation
Mechanical installation
SDo not modify the settings of screws and
threaded pins if there is no direct
requirement to do so in these operating
instructions.
SFit the motor onto the axis in accordance
with the assembly instructions for the
motor mounting kit recommended in the
catalogue.
Preparing the product for fitting
Note
Please note that in the case of heavy loadings the axis must not be fastened
only by the front cover.
Excessive tensile loads will cause the cover screws to be pulled out.
With use of the upper threaded holes in the
endcaps:
SEnsure the maximum screw-in depth of
7mm (with use of HP-25: use screw
M4x10).

Installing the product:
SSelect the necessary mounting position.
SCheck whether additional protection against entry of drops (grease, oil, water)
and particles is needed.

Fitting in a vertical or sloping position:
Warning
Masses falling suddenly can cause personal
injury and material damage (crushing).
If there is a power cut or if the toothed belt
breaks, the work load will slide down.
SMake sure that you only use motors with
an integrated spring-loaded holding brake.
SCheck whether additional external safety
measures are required to prevent the work
load from sliding down (e.g.toothed
latches, moving bolts or emergency
buffers).

With all mounting positions:
SPlace the DGE-...-ZR-RF so that all the
operating parts are accessible.
SMake sure that the device is fitted free
of mechanical stress and distortion
(evenness of mounting surface:
0.2 mm / 30 cm).
