Holding force and screw strength
The holding force of the System is essentially limited by the
strength of the screwed connections with which the clamping pin
is connected to the pallet or device. On this basis fastening
screws of the property class 12.9 are to be used only.
Only original SCHUNK Clamping-Pins are to be used.
When the clamping pin is used in the customer’s own assembly
device, the customer is to provide for a sufficiently dimensioned
tap and satisfactory strength of the fastening material.
Constructional changes, attachments, or modifications
Additional threads, bore holes or attachments which are not
supplied as accessories by SCHUNK may affect safety. They may
only be applied after obtaining the prior consent of SCHUNK.
Personnel qualification
The Quick Change Pallet System must only be installed, removed,
started up, operated and serviced by qualified specialist personnel
with the relevant safety training.
All persons charged with operating, maintaining and servicing this
Quick Change Pallet System must have access to the operating
manual, especially the chapter "Basic safety notes". We

Assembly
The item numbers to the corresponding individual parts refer to
the drawing in chapter 11.
Access to the drive piston (item 4) on the side must be ensured
during the assembly of the manually actuated quick change
pallet system, in particular in the event of clamped clamping
pallets. Check whether the drive piston is easy to access in order
to open or close the clamping module prior to the installation.
Wear protective equipment (protective gloves and safety shoes).
WARNING
Risk of injury due to falling down of the Quick Change Pallet
System during transport
Transport carefully.
Use a crane and/or a trolley for transport
CAUTION
Risk of injury due to squeezing
Install the Quick Change Pallet System carefully.
Don't get your limps in a gap between moving parts or clamping
fixture of the machine.
General assembly notes
If several clamping units are to be mounted in serial connection,
please make sure that the evenness and deviation in height of the
supporting surfaces from module to module keeps within 0.01 mm
(relating to a depth gauge of 200 mm). The deviation of the
interface position should not exceed ± 0.015 mm.
Due to the redundancy, clamping systems that are lying further
than 160 mm apart from each other or whose positioning
tolerance is not within ± 0.01 mm should use clamping pins with
positioning accuracy in one direction (SPB 40). For clamping
positions which are not used for alignment of the devices or
pallets, clamping pins with centric scope (SPC 40) can be used (see
also chapter 6.4).

Positioning of the module can be done via two different centering
diameters of the installation area:
Ø 138H6 (upper area)
Ø 110H6 (bottom area) depending on the installation version.
The clamping system is suitable for partial or complete installation
Partial installation should be preferred.
An access bore to the actuation connection must be provided in
the installation space for the complete installation.
Make sure the hexagon socket of the actuating piston is easy to
access at all times. An access bore of sufficient size ensures that
the access to the hexagon socket is well visible.
If any chips are in the access bore or hexagon socket, they have to
be removed prior to actuation.
The clamping system is driven manually by rotating the drive
piston (item 4). The drive piston is laterally in the base body (item
1).
The drive piston (item 4) is actuated with a hexagon screwdriver
(angled pin wrench). Symbols, engraved on the base body, indicate
the direction of rotation for locking or unlocking the clamping
area.
No air supply is required for the operation of the clamping system.
The openings on the base side therefore do not have to be sealed.

Change Pallet Modules, contact our technical customer service
Clamping pins SPA 40, SPB 40, SPC 40, SPG 40
CAUTION
Notes on clamping pins and fastening 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 fastened onto the workpiece or pallet in
2 different ways, the fastening variations are numbered in the
preferred sequence.
If the clamping pins have to be used for pallets that are not from
SCHUNK, e.g. customer-owned devices or items, the outer
diameter of the piece that has to be strained, has to be chosen at
least so big that the O-ring on the top of the particular quick
change pallet system is entirely covered.

6.4.1

Function
18 02|NSE-M plus 138 |en
Function
The item numbers to the corresponding individual parts refer to
the drawing in chapter 11.
The clamping system has a release mechanism with manual
actuation.
The actuating piston, which is actuated with a hexagon
screwdriver (angled pin wrench), can be accessed on the side of
the base body of the quick change pallet module.
A cam on the drive piston transfers the rotary movement to the
drive ring, which guides the clamping slides into the clamping area.
The clamping function is purely manual. No compressed air is
required. This makes the clamping system extremely flexible and
allows it to be used wherever no pressure medium is available.
Unlocking the clamping system
1 The manually actuated clamping system is unlocked by rotary
movement at the drive piston (item 4) which can be accessed
from the side. Insert the hexagon screwdriver in the hexagon
socket of the drive piston and turn it counter-clockwise.
2 The clamping slides (item 3) move outwards until the final
position of the rotary movement is reached.
3 The clamping pin is unlocked.
The clamping pins are available as separate accessories in four
versions (see chapter 6.4). They are mounted on customized
pallets or devices.
4 The pallet can be removed.
Locking the clamping system
1 The pallet can be inserted in the clamping system as soon as
the clamping slides are unlocked and the rotary movement at
the drive piston has reached the back stop.
2 Insert the pallet in the clamping system.
3 Insert the hexagon screwdriver in the hexagon socket of the
drive piston and turn it clockwise. After a few degrees of
rotation the unlocking position is leaved and the module closes
automatically.

Function
02|NSE-

4 The clamping slides are guided inwards by spring by means of
cams at the drive ring. When locking, the pallet is pulled onto
the contact surface of the clamping module and the clamping
pin is clamped in the clamping module in a self-locking and
form-fitting manner.
The clamping pin is centered at the taper bore of the clamping
module, which is why the angular alignment of the clamping
system can be selected as desired.

Maintenance and care
20 02|NSE-M plus 138 |en
Maintenance and care
The Quick Change Pallet System is designed for minimum-
maintenance operation, so that opening and disassembly of the
clamping modules is only necessary in exceptional cases.
If it is necessary to disassemble the quick change pallet system,
this may only be performed by trained specialist personnel.
• Clean all parts thoroughly and check for damage and wear.
Damaged and worn parts must be replaced.
• Grease the sliding surfaces of the guide curves in the drive
piston with LINO MAX 200.
• Grease the sliding surfaces of all movable components with
Renolit HLT 2.
Replace damaged parts only with original SCHUNK replacement
parts!
A repeated functional check is to be conducted before the start-
up.
General operating conditions
• Make sure that the bearing surface of the interface is always
clean.
• Please arrange the necessary, so that chips of any type can’t
get into the interface. Moreover, please avoid that coolant
emulsion fills up in the interface, espacially if the axis of the
clamping pin is vertically aligned. Both can be avoided by using
a protection cover SDE 138.
If the interface should nevertheless fill with coolant emulsion,
start locking and dry the interface during actuation.
• For operation, only high-quality coolant emulsions with rust-
protection additions should be used.
• Regularly inspect the units (at least every 2 weeks or after 1000
clamping cycles). Perfect operation is given whenever the
clamping slides move smoothly without increased application
of force when actuated by means of the piston. Safe operation
also includes the self-locking of the clamping area.
• Regularly inspect the system visually and control proper
function. In case of visible damages or signs of malfunction,
please stop the operation immediately. The system should not
be started up again, before all the damages are repaired. I.e. by
exchanging the damaged unit.
