Note
With hard and stiff useful loads:
If the slide
3 is bent due to a buckled use-
ful load, it will reduce the service life of the
drive.
• Make sure the mounting surface of the
useful load is even.

Effective loads with own guide:
• Adjust the guides of the effective load and of the DGC-K so that they are exactly
parallel.
In this way can you avoid overloading on the slide (Permissible forces
11 Technical data).
The driver DARD-L1 offers a torque-free and almost backlash-free power trans-
mission (
www.festo.com/catalogue).
5.2 Installation, pneumatic
For installation in a vertical or inclined position:
Warning
If there is a pressure drop, the movable load will drop down:
Danger of crushing!
• Check whether HGL non-return valves are necessary.
In this way, you can prevent the movable load from sliding down suddenly.
• Check whether safety measures are required to prevent sinking as a result of
leakage (e.g. toothed latches or moveable bolts).

• Select the suitable compressed air supply ports.
In addition to the supply ports provided at the factory (W), there are also the
alternative ports (A). These are fitted with plug screws.
For the linear actuator DGC-K of variant D2, the compressed air supply can be
made on both sides.
