General advice
This symbol indicates notes which may contribute to pre-
venting undesirable results or conditions.
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 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.
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.

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.
!
In order to avoid any injuries and any kind of damage please always make use of proper
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.
Generally the clamping set is supplied in mounted condition. Before assembly the clamping set has to be inspect-
ed for completeness.

Inspect the fit of shaft and hub for the tolerance specified (illustration 3).
Clean the surfaces of the clamping set marked in illustration 6 as well as of shaft and hub and afterwards ap-
ply thin fluid oil lightly (e. g. Ballistol Universal oil or Klüber Quietsch-Ex).
Illustration 6: Cleaning and lubricating the surfaces (example: CLAMPEX®KTR 125)
!
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 tab-
ular and calculated parameters deviate.
Unscrew the grooved nut (component 3) and insert the clamping set KTR 125 / KTR 125.1 between shaft and
hub.
!
The centering of the hub for KTR 125 must at least be as long as dimension B1(see table 1
or 2).
Lightly hand-tighten the grooved nut and align the clamping set with the hub part.
Tighten the grooved nut to the tightening torque TAspecified in table 1 or 2.
Having reached the tightening torque TAsecure the grooved nut by means of a locking washer.

During assembly the hub is displaced axially towards the shaft.
STOP
Driving components released or falling down may cause injury to persons or damage on the
machine.
Secure the driving components before disassembly.
Open the locking washer (component 4) and unscrew the grooved nut (component 3).
Disassembly of KTR 125:
The clamping set KTR 125 is not self-locking. If the inner and outer ring cannot be released, the process of re-
leasing should be initiated by putting some pressure on the hub and the grooved nut in several positions of the
circumference (see illustration 7).

Disassembly of KTR 125.1:

The clamping set KTR 125.1 is self-locking. You may expect an excessively difficult dis-
assembly.
If the inner and outer ring of KTR 125.1 cannot be released, the process of releasing should be initiated by
means of proper tools (assembly hammer) (see illustration 8).
Take out the clamping set released between shaft and hub.

Illustration 8: Releasing the clamping set KTR 125.1
!
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 ap-
ply thin fluid oil lightly (e. g. Ballistol Universal oil or Klüber Quietsch-Ex).
In respect of environmental protection please 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.
A basic requirement to ensure the operational readiness of the drive components is a stock of some clamping
sets on site.
Contact addresses of KTR partners for spare parts and orders can be obtained from the KTR homepage at

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.
CLAMPEX®clamping sets are not part of directive 94/9/EC, 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).
