2.3 General hazard warnings
STOP
With assembly and disassembly of the clamping set it has to be made sure that the entire
drive train is secured against accidental switch-on. You may be seriously hurt by rotating
parts. Please make absolutely sure to read through and observe the following safety indications.
All operations on and with the clamping set have to be performed taking into account "safety first".
Please make sure to switch off the power pack before you perform your work on the clamping set.
Secure the power pack against accidental switch-on, e. g. by providing warning signs at the place of switch-on
or removing the fuse for current supply.
Do not reach into the operation area of the machine as long as it is in operation.
Please secure the rotating drive components against accidental contact. Please provide for the necessary
protection devices and covers.
2.4 Intended use
You may only assemble and disassemble the clamping set if you
have carefully read through the operating/assembly instructions and understood them
had technical training
are authorized by your company
The clamping set may only be used in accordance with the technical data (see chapter 1). Unauthorized modifications on the clamping set are not admissible. We will not assume liability for any damage that may arise. In the
interest of further development we reserve the right for technical modifications.
The clamping set described in here corresponds to the technical status at the time of printing of these operating/assembly instructions.

Storage, transport and packaging
3.1 Storage
The clamping sets are supplied in preserved condition and can be stored at a dry and covered place for 6 - 9
months.
Humid storage rooms are not suitable.
Please make sure that condensation is not generated.
!
3.2 Transport and packaging
In order to avoid any injuries and any kind of damage please always make use of proper
transport and lifting equipment.
!
The clamping sets are packed differently each depending on size, quantity and kind of transport. Unless otherwise contractually agreed, packaging will follow the in-house packaging specifications of KTR.

Illustration 3: Components of clamping set
Dirty or used clamping sets have to be disassembled and cleaned before assembly. Afterwards the taper surfaces, threads and contact surfaces have to be lubricated with Molykote
MoS2 (see illustration 4). For re-lubrication please use the multi-purpose grease Molykote G
Rapid plus, as an example.

Assembly
4.2 Assembly of the clamping set
Inspect the fit of shaft and hub/hollow shaft for the tolerances specified in chapter 1 (illustration 2 and table 2).
The contact surfaces of hub/hollow shaft inside and shaft have to be cleaned and degreased (illustration 4).
!
The contact surfaces of shaft and hub bore (hollow
shaft inside) must neither be lubricated nor oiled
(see illustration 4).
!
When mounting the tapers of the clamping set free
from grease the tabular and calculated parameters
deviate.
Unscrew the clamping screws by several revolutions so that the
external rings lightly detach from the internal ring. Afterwards
shift the clamping set KTR 603 externally onto the hub or hollow
shaft, respectively.
The external surface of the hub (hollow shaft outside) can be lubricated in the area of the fit of external clamping set.
Illustration 4: Cleaning/lubricating the surfaces
Mount the shaft before tightening the clamping screws.
!
Hand-tighten the clamping screws for the time being and align the external clamping set with the shaft or hollow shaft.
Afterwards tighten the clamping screws stepwise one after another and with several revolutions until all
screws have achieved the full tightening torque as specified in table 1.
During assembly the hub is not displaced axially towards the shaft with KTR 603.
4.3 Disassembly of clamping set
STOP
Driving components released or falling down may cause injury to persons or damage on the
machine.
Secure the driving components before disassembly.
Unscrew the clamping screws evenly one after another. Do not fully unscrew the clamping screws out of the
thread.
To reduce the clamping forces do not fully unscrew the clamping screws in no case.
!
The clamping sets are not self-locking. If the front and rear external ring does not get detached, loosening
should be initiated by light pressure on the front and rear external ring in several positions on the periphery.
Remove the shaft from the hub/hollow shaft.
Pull the clamping set untightened from the hub/hollow shaft.
!
If these hints are not observed or operating conditions are not taken into account with the
selection of the clamping set, the operation of the clamping set may be affected.

Disposal
In respect of environmental protection we would ask you to dispose of the packaging or products on termination of
their service life in accordance with the legal regulations and standards that apply, respectively.
All clamping sets consist of metal. Any metal components have to be cleaned and disposed of by scrap metal.
6
Spares inventory, customer service addresses
A basic requirement to ensure the readiness for use of the drive components is a stock of some clamping sets on
site.
Contact addresses of the KTR partners for spare parts and orders can be obtained from the KTR homepage at
www.ktr.com.

KTR does not assume any liability or warranty for the use of spare parts and accessories
which are not provided by KTR and for the damages which may incur as a result.
Advice regarding the use in
2014/34/EU
hazardous locations according to EU directive
If used in hazardous locations the type and size of clamping set (for category 3 only) has to be selected such that
the difference between the peak torque of the machine including all operating parameters and the rated torque of
the clamping hub at least corresponds to a safety factor of s = 2.0.
®
CLAMPEX clamping sets are not part of EU directive 2014/34/EU, since
this product is a torsionally rigid, backlash-free, frictionally engaged connection with one or more taper clamping ring(s) by means of several screws.
(Clamping screws have to be secured, e. g. by means of a medium strength adhesive.)
due to the design of clamping sets a fracture/failure is not likely (frictional heat is only caused by improper
assembly/tightening torques, i. e. not with intended use).
