General advice
This symbol indicates notes which may contribute to
preventing adverse results or conditions.
STOP
With assembly, operation and maintenance of the measuring shaft 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 measuring shaft 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 measuring shaft.
•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 measuring shaft as long as it is in operation.
•Secure the rotating components of the measuring shaft against accidental contact. Please provide for the
necessary protection devices and covers.

You may only assemble, operate and maintain the measuring shaft if you
•have carefully read through the operating/assembly instructions and understood them
•had technical training
•are authorized by your company
The measuring shaft may only be used in accordance with the technical data (see chapter 1). Unauthorized
modifications on the measuring shaft 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 DATAFLEX®torque measuring shaft described in here corresponds to the technical status at the time of
printing of these operating/assembly instructions.
The RADEX®-N couplings are supplied in preserved condition. Both DATAFLEX®and RADEX®-N 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. The best relative air humidity is less
than 65 %.
!
In order to avoid any injuries and any kind of damage please always make use of proper
transport and lifting equipment.
The couplings are packed differently each depending on size, number and kind of transport. Unless otherwise
contractually agreed, packaging will follow the in-house packaging specifications of KTR.

The measuring shaft and the couplings are supplied as single pre-assembled component assemblies. Before
assembly the measuring shaft has to be inspected for completeness.
The mounting position of DATAFLEX®is variable. The measurement system can be mounted both horizontally
and vertically.

The maximum permissible bore diameters d1max and
d2max (see RADEX®-N catalogue) must not be
exceeded. If these figures are disregarded, the
coupling may tear. Rotating particles may cause
danger to life.
•Hub bores machined by the customer have to observe
concentricity or axial runout, respectively (see
illustration 4).
•Please make absolutely sure to observe the figures
for Ø d1max and Ø d2max.
•Carefully align the hubs when the finish bores are
drilled.
•Please provide for a setscrew according to
DIN EN ISO 4029 with a cup point or an end plate to
fasten the hubs axially.
Illustration 4: Concentricity and axial runout
The displacement figures specified in table 4 provide for sufficient safety to compensate for external influences
like, for example, thermal expansion or foundation settling.
!
In order to ensure a long service life of the measuring shaft, the shaft ends have to be
accurately aligned. Please absolutely observe the displacement figures specified (see
table 4). If the figures are exceeded, the measuring shaft with coupling will be damaged.
Please note:
•The displacement figures specified in table 4 are maximum figures which must not arise in parallel. If radial,
axial and angular displacement arises at the same time, these values must be reduced (see illustration 6).
•Please inspect with a dial gauge, ruler or feeler gauge whether the permissible displacement figures specified
in table 4 can be observed.

We recommend to inspect bores, shaft, keyway and feather key for dimensional accuracy
before assembly.
The power transmission is frictionally engaged. Fit pair of shaft-clamping ring hub is specified with H7/h6.
•Please clean and degrease the contact surfaces of the hub bores and the shafts before assembly.
!
Applying for RADEX®-N 135 only:
Oils and greases containing molybdenum disulfide or other high-pressure additives as well
as internal lubricants must not be used.
Applying for RADEX®-N 156 only:
Do not lubricate taper surfaces of the clamping ring hubs with initial assembly, since the
components are coated with lubricant when being supplied. For re-lubrication, for example
after disassembly, please use the multi-purpose fat Molykote G Rapid plus. Only use thin-
fluid oil for the threads of the clamping screws.
•Lightly unscrew the clamping scews, shift the clamping ring hub onto the shaft of the measuring shaft and
align to dimension L6.
•Tighten the clamping screws evenly crosswise. Increase the tightening torque stepwise.
Repeat this process until the tightening torque specified in table 5 has been achieved with all clamping screws.
•Applying for RADEX®-N 156 only:
No gap allowed between hub and clamping ring after tightening of all clamping screws (see illustration 8).

•Mount the hubs on the shaft of driving and driven side (see illustration 9). The ends of the shafts must not
protrude through the hubs.
•Shift the power packs in axial direction until the dimension L8is achieved.
•If the power packs are already firmly assembled, shifting the hubs axially on the shafts allows for adjusting the
distance dimension L8.

On request the hubs can be provided with a bore for setscrews for axial fastening. Please
specify in your order.
!
With the assembly please make sure that the distance dimension L8(see table 3) is
observed.
Disregarding this advice may cause damage to the measuring shaft (coupling).
