parts. Please make absolutely sure to read through and observe the following safety indica-
tions.
 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 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 chapter 1). Unauthorized modifica-
tions 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 operat-
ing/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 roofed 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 other-
wise 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 inspect-
ed for completeness.

4.1 Components of clamping set CLAMPEX® KTR 200 / KTR 201

Illustration 4: CLAMPEX® KTR 200 Illustration 5: CLAMPEX® KTR 201

With assembly none of the pull-off threads of the internal ring may be congruent with the
! slot of the external ring.


Dirty or used clamping sets have to be disassembled and cleaned before assembly. After-
wards apply thin fluid oil lightly (e. g. Ballistol Universal oil or Klüber Quietsch-Ex).

4.2 Assembly of the clamping set

 Inspect the fit of shaft and hub for the tolerance specified (illustration 3).
 Clean the contact surfaces of the clamping set and of shaft and hub and afterwards apply thin fluid oil lightly
(see illustration 6) (e. g. Ballistol Universal oil or Klüber Quietsch-Ex).

Illustration 6: Cleaning the contact surfaces (example: CLAMPEX® 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 signifi-
cantly must not be used. When mounting the tapers of the clamping set free from oil the
tabular and calculated parameters deviate.

 Release the clamping screws lightly. To facilitate the assembly fasten the internal and external ring by two
clamping screws each via the pull-off threads (see illustration 7). Insert the clamping set KTR 200 / KTR 201
between shaft and hub.

4.2 Assembly of the clamping set

Illustration 7: Fastening the clamping set (example: CLAMPEX® KTR 201)

 Remove the clamping screws used for fastening and screw them into the thread of the external ring.
 Lightly tighten the clamping screws manually and align the clamping set with hub part.
 Please make sure with KTR 201 that the axial back-up ring (component 3) fits the hub evenly.
 Tighten the clamping screws evenly crosswise step by step 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 towards the shaft with KTR 200.

4.3 Disassembly of clamping set

Driving components released or falling down may cause injury to persons or damage on the
STOP machine.
Secure the driving components before disassembly.

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

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 operational readiness 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.

7 Advice regarding the use in hazardous locations according to EU directive

2014/34/EU

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 directive 2014/34/EU, since
 this product is a torsionally rigid, backlash-free, frictionally engaged connection with one or more taper clamp-
ing 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).
