3 Function and application
When the compressed air supply ports are pressurised reciprocally, the internal slide in the cylinder
barrel moves back and forth. The rigid connection causes the slide 5 to move too. The slot in the cyl-
inder barrel required for this is covered by a belt system. The slide is mounted on a roller bearing. The
reference position of the slide can be queried with the help of proximity sensors in the slots aA.

The linear drive DGC-...-HD is intended for positioning payloads with large masses. It is approved for
the slide and yoke operating mode (èobserve load limits).
Fig. 2 Slide mode
Fig. 3 Yoke mode
Unpressurised movement of the slide is permitted only for fault clearance and at low speeds. If the
speed is too high, the negative pressure that occurs can pull the sealing band into the piston chamber.
This can lead to:
– High leakage and
– Impermissible acceleration (e.g. with a vertical mounting position).
4 Transport and storage
NOTICE!
• Avoid touching the guide rail with your hands during transport and storage, as this will damage
the grease film.
– Take the product's weight into account. The DGC-HD weighs up to 100kg depending on the
design. For transport, the conveyors must be spaced according to the permissible support spa-
cings (support spacings è 13 Characteristic curves).
– Ensure storage conditions as follows:
– Short storage times
– Cool, dry, well-shaded, corrosion-resistant locations.
5 Requirements for product use
NOTICE!
Malfunctions will occur if the device is incorrectly used.
• Make sure that the specifications contained in this chapter are adhered to at all times.
– Take into consideration the legal regulations applicable for the location as well as:
– Regulations and standards
– Regulations of the testing organisations and insurers
– National specifications
– Observe the warnings and notes on the product and in the relevant operating instructions.
– Remove transport packaging, such as films, caps and cardboard.
The material used in the packaging has been specifically chosen for its recyclability (exception:
