Fastening and connection
Flatness
If several linked clamping modules are mounted, make sure that
the flatness and height deviation of the locating surfaces from
module to module (based on a 100 mm gauge for bore holes) is
≤ 0.02 mm. The gauge deviation may not exceed ± 0.015 mm.
Agreement
Due to redundancy, the clamping pins with positioning accuracy in
one direction (SPB mini 20) should be used for clamping systems
that are more than 100 mm apart or that do not show a
positioning tolerance of ± 0.01 mm. For the clamping areas that
are not intended for alignment of the device or pallet, clamping
pins with centering clearance (SPC mini 20) can be used (also refer
to chapter "Clamping pins" ( 4.4, Page 23)
).
Air bleed screw for the piston chamber
When connecting the quick-change pallet systems, it must be
taken into consideration that it is only possible to completely
ventilate the piston chamber via the air connections during the
locking process. The relevant valves or shut-off valves should
therefore be equipped with load relief.
This also applies to the turbo connection. If the turbo connection
is not used, the relevant side of the piston must have a way of
being ventilated. This is optimally done via the turbo connection
itself.
Alternatively, a ventilation option can be created by removing the
set-screw M5 x 4 in the module cover.

20 01.00|NSE mini 90-25, NSE mini 90-25-V10 |en
Turbo connection
When using the turbo connection (if supply is connected), the
spring actuated locking procedure is actively supported with air
pressure and in so doing strengthens the achievable pull-in force
of the quick-change clamping system. For force amplification, a
pressure pulse is sufficient, the pressure line can be decoupled,
the pull-in force remains intact. If the turbo connection is not
used, the relevant side of the piston must be able to ventilate.
Connecting hose lines
If several quick-change systems are activated via jointly connected
hose lines, feed lines with the following minimum cross-sections
must be used.
Minimum nominal hose width
When disconnecting hose lines, the relevant openings of the air
supply connections must be protected with seal plugs or sealing
caps to prevent the ingress of dirt or cooling lubricant.

Fastening in the installation space with 6 M6 screws.
The assembly module is positioned using the centering diameter of
the installation space: Ø 66 H6.
The air connection is normally made via the coupling
holes in the floor of the unit.
Alternative connection option: two M5 connections on the side. In
this case, the bottom opening must be sealed.
Either by inserting the O-ring Ø 8 x 1 and placing it on a flat

the installation space: Ø 66 H6.
The exact position orientation is done with a fitting screw with a
diameter of Ø 6 f7 x 3 mm.
Precise alignment and positioning of the quick-change pallet
system requires that the fitting bore Ø 6H7 on the opposite side is
precisely positioned in the mounting position.
The air connection is normally made via the coupling
holes in the floor of the unit.
Alternative connection option: two M5 connections on the side. In

Notes on clamping pins and mounting screws
The holding force of the quick-change pallet system is limited
essentially by the tightness of the screw connection which
connects the clamping pin to the pallet or the device. This is why
only screws of strength class 12.9 may be used.
Only original SCHUNK clamping pins may be used.
If the clamping pins are to be used in customer-owned devices,
the customer must provide sufficiently dimensioned threaded
holes or a sufficiently thick mounting material.
The clamping pins can be attached to the device or pallet in two
different ways. The mounting variant on the left in the illustration,
which is screwed from above, is the preferred variant. With this
variant, if there is a module failure then the device or pallet can be
removed after disassembling the clamping pins.

It is possible to monitor the dynamic pressure of the clamping slide
position. Pressure build-up in "OPENED" status. Control of the
clamping slide monitor requires a reduced pressure supply limited
to 2 bar (see chapter "Pneumatic circuit diagram"
( 4.6, Page 26)
).
The measurable differential pressure must reach a minimum of
0.5 bar in order for a reliable evaluation to be done via the air
gap sensor. The maximum pressure is 2 bar. Monitoring requires
a pressure gauge, an adjustable throttle and an air gap sensor.
For monitoring of the clamping slide, the predefined connection
must be accessed via a base side bore hole.
Request our installation drawings if doing the installation yourself.

When changing the pallet using lifting equipment or a robot,
ensure that the pallet is lifted exactly parallel to the modules.
The inclination (X) during lifting may not exceed 1.2°.
If the inclination is larger, the clamping pins can jam and the
system components could be damaged or destroyed. In this
case, the system must be inspected and damaged parts must be
replaced immediately.
Only original SCHUNK spare parts may be used!
Risk of injury due to losing pallets or workpieces in the case of
incorrect actuation caused by incorrect operation.
Risk of injury due to compressed air hoses coming loose when
connected improperly.
• Disconnect the energy supply after locking.
• Use check valves or safety switches.
• The danger zone must be surrounded by a protective
enclosure during operation.
Risk of injury due to losing pallets or workpieces if the supply of
compressed air drops or fails, and due to the clamping pins
immediately closing
• Do not reach into the clamping module.
• Use pressure maintenance valves.

01.00|NSE mini 90-25, NSE mini 90-25-
Maintenance and care
The quick-change pallet system is designed for low-maintenance
operation, so that opening and disassembling the clamping
modules is only necessary in exceptional cases.
Risk of injury and risk of damage to the clamping module when
opening the housing cover.
If the clamping module has to be disassembled, send the
module to SCHUNK for repair.
The covers of the clamping modules are spring preloaded and
may only be removed by trained specialist personnel. The
covers can only be disassembled and assembled using a special
assembly tool and by observing the corresponding disassembly
and assembly instructions.
To ensure the quick-change pallet system operates perfectly, the
following instructions are to be observed:
Pressure medium: Compressed air, compressed air quality
according to ISO 8573-1:7 4 4
• Check the units at regular intervals (at least every two weeks or
after 10000 clampings).
The system is functioning correctly if the clamping slides move
smoothly at minimum system pressure (5 bar).
• Carry out regular visual/functional checks. In case of visible
damage or signs of malfunction, shut down the quick-change
pallet system immediately.
The system may only be commissioned again once the faults
have been corrected. For example, by replacing the damaged
unit.
