The ROTEX®BTAN / SBAN is a failsafe torsionally flexible jaw type coupling with brake drum or
brake disk. It is able to compensate for shaft displacements caused by, for example, inaccuracies in
production, heat expansion etc.
General Hints
Please read through these mounting instructions carefully before you set the coupling into operation.
Please pay special attention to the safety instructions!
The mounting instructions are part of your product. Please keep them carefully and close to the
coupling.
The copyright for these mounting instructions remains with KTR Kupplungstechnik GmbH.
Safety and Advice Hints
STOP DANGER ! Danger of injury to persons.

CAUTION ! Damages on the machine possible.
FATTENTION ! Pointing to important items.
General Hints to Danger
STOP DANGER !
With assembly, operation and maintenance of the coupling 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 coupling have to be performed taking into account "safety first".
•Please make sure to disengage the power pack before you perform your work.
•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 coupling as long as it is in operation.
•Please protect the coupling against unintentional touch. Please provide for the necessary
protection devices and caps.
Proper Use
You may only assemble, operate and maintain the coupling if you
•have carefully read through the mounting instructions and understood them
•and if you are authorized and have proper skills
The coupling may only be used in accordance with the technical data (see ROTEX®catalogue).
Unauthorized modifications on the coupling design 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 ROTEX®BTAN / SBAN described in here corresponds to the technical status at the time of
printing of these mounting instructions.

Basically the coupling is supplied in individual parts. Before assembly the coupling has to be controlled for
completeness.

Mounting Hint
STOP DANGER !
The maximum permissible bore diameters d1max and
d2max (see ROTEX®catalogue) must not be exceeded. If
these figures are disregarded, the coupling may tear.
Rotating parts may cause serious danger.
•Hub bores machined by the customer have to observe
concentric running or axial running, respectively (see
picture 4).
•Please make absolutely sure to observe the figures for
d1max and d2max.
•Carefully align the hubs when the finish bore is brought
in.
•Please provide for a setscrew or an end plate for the
axial fastening of the hubs. picture 4: concentric and axial running
Assembly of the hubs
FATTENTION !
We recommend to check bores, shaft, keyway and feather key for dimensional accuracy
before assembly.
Heating the hubs slightly (approx. 80° C) allows for an easier installation onto the shaft.
STOP DANGER !
Touching the heated hubs may cause burns.
We would recommend to wear safety gloves.
Assembly of the coupling
!
CAUTION !
For the assembly please make sure that the distance dimension E (table 2) is kept to
ensure that the spider can be moved axially when in operation.
Disregarding this hint may cause damage on the coupling.
•Assemble the FN hub with the brake drum / brake disk. Tighten the screws with a suitable torque wrench to
the tightening torques TA(see picture 5).
FATTENTION !
Before tightening the screws please put Loctite 243 on the threads.
•Assemble the hub and the FN hub with the brake drum / brake disk onto the shaft of the driving side and the
driven side. Put the FN hub onto the shaft end where the bigger mass moment of inertia becomes effective.
The max. braking torque must not be bigger than the max. torque (Tkmax) of the coupling (see picture 6).
•Secure the hubs by fastening the grub screws DIN 916 with splined cup point or by an end plate.
•Install the spider inside the cams of the hub (see picture 7).
•Push the machines to be connected together until the distance dimension E is achieved.

!
CAUTION !
Having set the coupling into operation, the tightening torque of the screws and wear of
spider have to be inspected in usual maintenance intervals and exchanged, if necessary.

Displacements
The displacement figures shown in table 2 offer sufficient safety to compensate for environmental influences
like, for example, heat expansion or lowering of foundation.
!
CAUTION !
In order to ensure a long lifetime of the coupling, the shaft ends have to be aligned
accurately. Please absolutely observe the displacement figures indicated (see table 2). If
the figures are exceeded, the coupling will be damaged.
Please note:
•The displacement figures mentioned in table 2 are maximum figures which must not arise in parallel. If radial
and angular displacement arises at the same time, the permissible displacement values may only be used in
part.
•Please check with a dial gauge, ruler or feeler whether the permissible displacement figures of table 2 can be
observed.
