Gripping Systems
Flagship gripper is now also
available in a dust-proof and
ATEX-certified version
SCHUNK INTEC INDIA PRIVATE LIMITED
CHUNK is expanding its range of
legendary PGN-plus-P universal
grippers. All sizes of the PGN-plus-P
are now also available as ATEX version
for the use in potentially explosive
areas. By the end of the year, all sizes
will also be available in dust-proof
version as part of the SCHUNK catalog
range along with corresponding
retrofit kits for existing grippers. What
is special about this is that the dust-
proof version is combinable with other

A dust-proof version of the SCHUNK PGN-

SCHUNK is offering dust protection retrofit kits
for existing grippers.
Lifelong maintenance-free
With the PGN-plus-P, SCHUNK pursues
a clear objective: more performance

equipment features such as ATEX,
corrosion protection, high-temperature
or precision version, so that users are
particularly flexible when selecting
the equipment variants. In addition,
SCHUNK is also expanding the range of
sizes. This year, the sizes 40, 160 and 240
are added, meaning the entire range
from 40 to 240 with gripping forces of
160 N to 5,000 N and permissible finger
lengths from 65 mm to 355 mm will be
covered as standard.
reduces investment costs. The fact that
the supporting dimension between the
six weight-bearing shoulders of the
patented multi-tooth guidance was
increased two years ago by up to 40%
and the surface of the oval piston by
around 15% has caused quite a stir on
the market. It was suddenly possible
to absorb higher torques, insert
longer fingers, and handle heavier
components. Users quickly realized that
this reserve capacity is also worthwhile
even if the power limit is not touched.
The new design of the SCHUNK mega-
seller minimizes wear and increases life
span, even under normal loads. This
also fits to the fact that the already
large diagonal pull surface of the wedge
hook drive of the new PGN-plus P was
enlarged even further, minimizing
wear and increasing process reliability.
In addition, circumferential lubricant
pockets on the multi-tooth guidance
ensure permanent lubrication of the
sliding surfaces, and the grippers
operate maintenance-free under clean
operating conditions for their entire life
span. Tests in SCHUNK’s own product

modules have a significant edge over

considered of being a benchmark all over the
world in the field of universal grippers.

are not uncommon. But what is even
more important from the user’s point
of view, is the high process reliability
of the modules, which is important for
ensuring trouble-free plant operations.
Large variety of options
The range of equipment of the PGN-
plus-P family is extraordinary. SCHUNK
has integrated possibilities for screw
connections, supports or centering
as standard. In order to ensure an
even distribution of air purge in the
interior of the grippers, and the air
purge connection was located in the
middle. On request, the modules are
also available with a spring safety
device for mechanical gripping force
maintenance, and with compensation
units for compensating angular errors.
The sensor program is also impressive:
Ranging from inductive proximity
switches with especially easy-to-adjust
control cams, fully integrated electronic
magnetic switches, and flexible
position sensors, for detecting up to
five positioning areas right up to high-
resolution analog sensors, which enable
measuring accuracies of up to 0.03 mm.
Moreover, SCHUNK provides special
radio sensor systems, which monitor
the stroke of the gripper jaws wirelessly
for the use in machines, in confined
spaces, or aggressive environments,
where cables would endanger process
stability.
