Warning
When exhausting:
• Make sure that the gripper is not holding a working load.
In this way you can prevent a working load from falling down suddenly.
Note
Installation and commissioning is to be carried out only by qualified personnel in
accordance with the operating instructions.

Function and application
Ventilation of the supply port
3
causes an internal piston to move. A mechanism
4
transmits the movement of the piston to the bellows
5
. This causes the bel-
lows to deform outward.
The enlargement of the bellows diameter jams useful loads to the inner contour.
If the gripper is exhausted, the resetting force of the bellows pushes the piston to
the initial position.
The bellows gripper DHEB is intended for gripping and holding work loads.

Requirements for product use
• Compare the maximum values specified in these operating instructions with
your actual application (e.g. pressures, forces, torques, temperatures, masses,
speeds). Only observance of the load limits allows operation of the product in
compliance with the relevant safety regulations.
• Take 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.
• Ensure that the compressed air is properly prepared (
Technical data).
• Maintain the selected medium for the complete service life of the product.
Example: Always use non-lubricated compressed air.
• Pressurise your entire system slowly. This ensures that there will not be any
uncontrolled movements. For slow start-up pressurisation, use on-off valve HEL.
• Comply with the regulations of the German Technical Control Board (TÜV), trade
association or relevant national regulations.
• Remove all transport packaging such as foils, caps and cartons (except for any
plugs in the pneumatic connections).
It is intended that the packaging be recycled on the basis of its constituent ma-
terials (exception: oiled paper = general waste).
• Use the product in its original state without any unauthorised modifications.
• Note the warnings and instructions on the product and in the relevant operating
instructions.
• Take the tolerance of the tightening torques into account.
Unless otherwise specified, the tolerance is ±20 %.

Mechanical installation
• Make sure there is sufficient room for the connection elements.
If proximity sensors are used:
• Mount the sensor bracket.
• Push the proximity sensor into the
slots of the sensor rail.
• Please check the following points:
– Interference caused by ferritic
mounting parts (e.g. by mounting
screws made of ferritic steel).
– Possibly protruding proximity
sensors.
– Minimum clearance L of the DHEB
according to following table.
