Heavy-duty three-point grippers HGDT
Key features
At a glance
The force generated by the linear
motion is translated into the gripper
jaw movement via a force-guided
triple wedge mechanism. This also
guarantees synchronous movement
of the gripper jaw. The virtually
backlash-free slideway is realised
using ground-in gripper jaws.
A wide range of uses:
Double-acting gripper
Compression springs for supple
menting or retaining gripper forces,
or for use as a single-acting gripper
with only one compressed air
connection
Suitable for external and internal
gripping
Sealing air connection:
Compressed air flows past the gripper
jaw when sealing air (max. 0.5 bar) is
connected.
This prevents particles and soluble
oil, etc. from entering the gripper jaw
guides.
There are two variants available:
Standard – HGDT-…
Stroke per gripper jaw:
3 … 10 mm
Total gripping force:
207 … 1728 N
High force – HGDT-…-F
Stroke per gripper jaw:
1.5 … 5 mm
Total gripping force:
411 … 3372 N
