General Hints to Danger
STOP
DANGER!
With assembly and disassembly of the clamping set it has to be made sure that the
entire drive train is protected against unintentional engagement. You can be
seriously hurt by rotating parts. Please make absolutely sure to read through and
observe the following safety instructions.
•All operations on and with the clamping set have to be performed taking into account "safety first".
•Please make sure to disengage the power pack before you perform your work at the clamping set.
•Protect the power pack against unintentional engagement, e. g. by providing hints at the place of
engagement or removing the fuse for current supply.
•Do not touch the operation area of the machine as long as it is in operation.
•Please protect the rotating drive parts against unintentional touch. Please provide for the necessary
protection devices and caps.
Proper Use
You may only assemble and disassemble the clamping set if you
•have carefully read through the mounting instructions and understood them
•had technical training
•are authorized to do so by your company
The clamping set may only be used in accordance with the technical data (see table 2). Unauthorized
modifications on the clamping set are not admissible. We do not take any warranty for resulting
damages. To further develop the product we reserve the right for technical modifications.
The CLAMPEX®clamping set described in here corresponds to the technical status at the time of
printing of these mounting instructions.

Tolerances, surfaces
A good rotating process is sufficient: Highest permissible tolerance:
Rz ≤16μm d = f7 for the hub (hollow shaft outside)
dW= h6/ H7
dW> Ø160 - g6/H7

Assembly
Continuation:
•Loosen the clamping screws slightly and put the clamping set KTR 620 externally onto the hub/hollow shaft
(see picture 3 and 4).
)ATTENTION!
In the area of the position of the external clamping set the external surface of the hub
(outside hollow shaft) can be greased.
!
CAUTION!
Before tightening the clamping screws install the shaft.
•Slightly tighten the clamping screws manually.
•Afterwards tighten the clamping screws evenly and successively in several revolutions (see picture 5) until the
front, screw head-sided surfaces of the outer and the inner ring are flush. Thus the correct clamping of the
outer and the inner ring can be visually checked (see picture 6).
When tightening the clamping screws the max. screw tightening torque indicated (see table 1) must not be
exceeded.
)ATTENTION!
Subject to the QPQ coating the internal ring may protude by up to 0,5 mm.

Disassembly
STOP
DANGER!
Loosened or falling drive parts can cause injuries to persons or damages to the machines.
Safe the drive parts before the disassembly.
•Detach all clamping screws evenly and successively in several revolutions.Do not unscrew the clamping
screws completely from the thread.
!
CAUTION!
To reduce the tension forces the clamping screws must not be unscrewed completely.
•Detach the outer taper ring by means of the pull-off threads and some clamping screws, quantity dependent
on the pull-off threads in the inner ring. The outer taper ring must be pulled as long as this is completely
detached.
•Remove shaft from the hub/hollow shaft.
•Draw the clamping set KTR 620 off the hub/hollow shaft.
!
CAUTION!
In case of non-observance of these hints or in case of non-considerance of the operating
conditions regarding the selection of the clamping set, the function of the clamping set can
be influenced.
Disposal of waste: Defective clamping sets must be cleaned and scrapped.
Remark for the use in explosive applications according to ATEX 95
For the use in explosive applications the type and size of clamping set (applying for category 3 only) has to be
selected in a way that starting from the peak torque of the machine including all operating parameters to the rated
torque of the clamping set there is a service factor of at least s = 2.
CLAMPEX®clamping sets are not part of the standard 94/9/EG, 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 does not have to be expected (frictional heat is only
caused by improper assembly/tightening torques, i. e. not in case of proper use).
