Advice
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.
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
• are technically qualified and specifically trained (e. g. safety, environment, logistics)
• 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.

With assembly none of the extraction threads of the internal ring (component 2) must be
congruent with the slot of the external ring (component 1).
Dirty or used clamping sets have to be disassembled and cleaned before assembly. Afterwards apply thin oil lightly (e. g. Ballistol Universal oil or Kl&uuml;ber Quietsch-Ex).

Assembly
4.2 Assembly of the clamping set
• Inspect the fit of shaft and hub for the tolerance specified (see illustration 3).
• Clean the surfaces of the clamping set marked in illustration 6 as well as of shaft and hub and afterwards
apply thin oil lightly (e. g. Ballistol Universal oil or Kl&uuml;ber Quietsch-Ex).
Illustration 6: Cleaning and lubricating the contact surfaces (example: CLAMPEX&reg; KTR 201)
!
Oils and greases with molybdenum disulphide or other 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 by several revolutions so that the external ring detaches slightly from the internal ring.
• To facilitate the assembly fasten the internal and external ring by two clamping screws via the extraction
threads (see illustration 7). Afterwards insert the clamping set KTR 200 / KTR 201 between shaft and hub.
Illustration 7: Fastening the clamping set (example: CLAMPEX&reg; KTR 201)
• Remove the clamping screws used for fastening and screw them into the thread of the external ring.
• Hand-tighten the clamping screws first and align the internal clamping ring with the hub.
• Please make sure with KTR 201 that the axial back-up ring (component 3) for axial fastening fits the hub
evenly.
• Tighten the clamping screws evenly crosswise gradually to the tightening torque specified in table 1 or 2.
Repeat this process until all clamping screws have reached the tightening torque.

During assembly the hub is displaced axially to the shaft with KTR 200.

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.
• Untighten and unscrew all clamping screws evenly one after another.
• Screw the clamping screws into the extraction threads of the internal ring (component 2) (see illustration 8 and
9).
• Tighten the clamping screws evenly crosswise by 1/4 revolution. Increase the extraction torque gradually until
the external ring (component 1) and internal ring (component 2) are separated.
• Take out the clamping set released between shaft and hub.

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.
Used clamping sets have to be disassembled and cleaned before assembly. Afterwards
apply thin oil lightly (e. g. Ballistol Universal oil or Kl&uuml;ber Quietsch-Ex).
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.

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

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 in 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&reg; clamping sets are not part of directive 2014/34/EU, since
• this product is a torsionally rigid, backlash-free, frictionally engaged connection with one or more taper clamping ring(s) ensured by 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 generated by improper
assembly/tightening torques, i. e. with use other than for intended purpose).

Frequently asked questions

The maximum torque that can be transmitted varies depending on the size of the clamping set. Please refer to Table 1 or 2 in the viewed document for specific torque ratings.

Apply a thin layer of oil, such as Ballistol Universal oil or Klüber Quietsch-Ex. Do not use oils or greases with molybdenum disulphide, Teflon, or silicone additives.

Unscrew all clamping screws evenly. Screw the clamping screws into the extraction threads of the internal ring and tighten them evenly until the external and internal rings are separated. Then remove the clamping set from the shaft and hub.
