General advice
This symbol indicates notes which may contribute to preventing adverse results or conditions.
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 &quot;safety first&quot;.
 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.

Advice
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 table 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.
3
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.
4
Assembly
Generally the clamping set is supplied in mounted condition. Before assembly the clamping set has to be inspected for completeness.
Please observe protection

Dirty or used clamping sets have to be disassembled and cleaned before assembly. Afterwards apply thin fluid oil lightly (e. g. Ballistol Universal oil or Kl&uuml;ber Quietsch-Ex).
4.2 Assembly of clamping set

Please inspect the shaft fit for the tolerance specified (h8).

Please clean and degrease the contact surfaces of the shafts to be combined. Afterwards apply thin fluid oil
lightly (e. g. Ballistol Universal oil or Kl&uuml;ber Quietsch-Ex).
!
Oils and greases with molybdenum disulphide or high-pressure additives, additives of Teflon and silicone as well as internal lubricants reducing the coefficient of friction significantly must not be used. When mounting the tapers of the clamping set free from oil the tabular
and calculated parameters deviate.

Unscrew the clamping screws (do not fully unscrew) and fit the clamping set KTR 700 spec. (rigid shaft coupling) on the shaft ends to be connected.

Lightly tighten the clamping screws manually and align clamping set and shafts (see illustration 3).

Assembly
4.2 Assembly of clamping set

Tighten the clamping screws evenly crosswise step by step to the tightening torque specified in table 1. The
process needs to be repeated until the tightening torque has been achieved with all screws.
4.3 Disassembly of clamping set
Driving components released or falling down may cause injury to persons or damage on the
machine.
Secure the driving components before disassembly.
STOP

Unscrew the clamping screws evenly one after another. Do not fully unscrew the clamping screws out of the
thread.

The clamping sets are not self-locking. If the front and rear external taper ring cannot be released, the process of releasing should be initiated by putting some pressure on the front and rear external taper ring in several positions on the circumference.

Pull the shaft ends out of the clamping set KTR 700.
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.
!
5
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
rective 2014/34/EU
potentially explosive atmospheres according to EU di-
If used in potentially explosive atmospheres, 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.
&reg;
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).

Frequently asked questions

The CLAMPEX® KTR 700 is a frictionally engaged, detachable shaft-to-shaft connection for cylindrical shafts without feather key. It is used to connect two shafts together in a way that allows for easy disassembly.

The shafts that can be used with the CLAMPEX® KTR 700 must have a tolerance of h8.

Thin fluid oil, such as Ballistol Universal oil or Klüber Quietsch-Ex, should be used when assembling the CLAMPEX® KTR 700. Oils and greases with molybdenum disulphide or high-pressure additives, Teflon, silicone, or internal lubricants reducing the coefficient of friction significantly must not be used.
