You may only assemble, operate and maintain the coupling if you
have carefully read through the operating/assembly instructions and understood them
had technical training
are authorized by your company
The coupling may only be used in accordance with the technical data (see chapter 1). Unauthorized modifications
on the coupling design 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 ROTEX®AFN-SB spec. described in here corresponds to the technical status at the time of printing of these
operating/assembly instructions.
!
For a permanent and failure-free operation of the coupling it must be selected according to
the selection instructions (according to DIN 740 part 2) for the particular application (see
catalogue drive technology "ROTEX®").
If the operating conditions (performance, speed, modifications on engine and machine)
change, the coupling selection must be reviewed.
Please make sure that the technical data regarding torque refer to the spider only. The
transmittable torque of the shaft-hub-connection must be reviewed by the customer and is
subject to his responsibility.
For drives subject to torsional vibrations (drives with cyclic stress due to torsional vibrations) it is necessary to
perform a torsional vibration calculation to ensure a reliable selection. Typical drives subject to torsional vibrations
are e. g. drives with diesel engines, piston pumps, piston compressors etc. If requested, KTR will perform the
coupling selection and the torsional vibration calculation.
The couplings supplied by KTR should be considered as components, not machines or partly completed
machines according to EC Machinery Directive 2006/42/EC. Consequently KTR does not have to issue a
declaration of incorporation. For details about safe assembly, start-up and safe operation please refer to the
present operating/assembly instructions considering the warnings.
The couplings are supplied in preserved condition and can be stored at a dry and covered place for 6 - 9 months.
The features of the coupling spiders (elastomers) remain unchanged for up to 5 years with favourable storage
conditions.
!
The storage rooms must not include any ozone-generating devices like e. g. fluorescent
light sources, mercury-vapour lamps or electrical high-voltage appliances.
Humid storage rooms are not suitable.
Please make sure that condensation is not generated. The best relative air humidity is less
than 65 %.

The maximum permissible bore diameters d (see
table 1 and 2 in chapter 1 - technical data) must
not be exceeded. If these figures are
disregarded, the coupling may tear. Rotating
particles may cause danger to life.
Bores on the coupling flange machined by the
customer have to observe concentricity or axial
runout, respectively (see illustration 3).
Please make absolutely sure to observe the
figures for Ø dmax.
Please review the length of the centering spigot lx
(see table 3). lx= b1+ lz
Carefully align the coupling flanges 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 coupling flanges axially.

We recommend to inspect bores, shaft, keyway and feather key for dimensional accuracy
before assembly.
Heating the coupling flanges lightly (approx. 80 °C) allows for an easier mounting on the
shaft.
STOP
Touching the heated coupling flanges causes burns.
Please wear safety gloves.
!
With the assembly please make sure that the distance dimension E or E1(see table 1) is
observed to allow for axial clearance of the spider when in operation.
Disregarding this advice may cause damage to the coupling.
Mount the coupling flanges (component 4Nv and 4Nx) onto the shaft of driving and driven side. The coupling
flange (component 4Nx) for the assembly of the brake disk (component 15Nx) has to be mounted to the shaft
end which has the bigger mass moment of inertia (see illustration 4).
The internal sides of the coupling flanges (component 4Nv and 4Nx) must be flush with the front sides of the
shafts (see illustration 4).
Shift the power packs in axial direction until the distance dimension E1is achieved (see illustration 4).
Fasten the coupling flanges (component 4Nv and 4Nx) by tightening the setscrews DIN EN ISO 4029 with a
cup point (tightening torque see table 4) or an end plate.
Mount the brake disk (component 15Nx) onto the centering shoulder of the coupling flange (component 4Nx)
(see illustration 5).
Stick the driving flanges (component 3Na) and the spider (component 2) together (see illustration 6).
Install the components sticked together between the coupling flanges (component 4Nv and 4Nx) (see
illustration 7) and hand-tighten the components with the cap screws (component 1a and 1b) first.
Tighten the screws at the tightening torques TAspecified in table 1 by means of a suitable torque key.
Center the spider (component 2) between the driving flanges (component 3Na) and check the dimensions E
and s (see illustration 1).

Having started up the coupling, the tightening torque of the screws and the wear of spider
have to be inspected at regular maintenance intervals and the spider has to be replaced, if
necessary.
The displacement figures specified in table 6 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 coupling, the shaft ends have to be accurately
aligned. Please absolutely observe the displacement figures specified (see table 6). If the
figures are exceeded, the coupling will be damaged.
The more accurate the alignment of the coupling, the longer is its service life.
Please note:
The displacement figures specified in table 6 are maximum figures which must not arise in parallel. If radial
and angular displacements arise at the same time, the permissible displacement values may only be used
proportionally (see illustration 9).
Please inspect with a dial gauge, ruler or feeler gauge whether the permissible displacement figures specified
in table 6 can be observed.

Before start-up of the coupling, inspect the tightening of the setscrews in the coupling flanges, the alignment and
the distance dimension E or E1and adjust, if necessary, and also inspect all screw connections for the tightening
torques specified, dependent on the type of coupling.

The setscrews to fasten the flange hubs as well as all screw connections must be secured
against working loose additionally, e. g. conglutinating with Loctite (average strength).
Finally the coupling protection against accidental contact must be fitted. It is required in accordance with
DIN EN ISO 12100 (Safety of Machinery) and must protect against
access with the little finger
falling down of solid foreign objects.
The cover may provide for openings intended for necessary heat dissipation. These openings have to comply with
DIN EN ISO 13857.
The cover must be electrically conductive and included in the equipotential bonding. Bellhousings (magnesium
share below 7.5 %) made of aluminium and damping rings (NBR) can be used as connecting element between
pump and electric motor. The cover may only be taken off with standstill of the unit.

During operation of the coupling, please pay attention to
different operating noise
vibrations occurring.
!
If you note any irregularities with the coupling during operation, the drive unit must be
switched off immediately. The cause of the breakdown must be specified by means of the
table „Breakdowns“ and, if possible, be eliminated according to the proposals. The potential
breakdowns specified can be hints only. To find out the cause all operating factors and
machine components must be considered.
The below-mentioned failures can lead to a use of the ROTEX®coupling other than intended. In addition to the
specifications given in these operating and assembly instructions make sure to avoid such failures.
The errors listed can only be clues to search for the failures. When searching for the failure the adjacent
components must generally be considered.
General failures with use other than intended:
Important data for the coupling selection were not forwarded.
The calculation of the shaft-hub-connection was disregarded.
Coupling components with damage occurred during transport are assembled.
If the heated coupling flanges are assembled, the permissible temperature is exceeded.
The fit of the components to be assembled is not coordinated with one another.
Tightening torques have been fallen below/exceeded.
Components are mixed up by mistake/assembled incorrectly.
A wrong or no spider is inserted in the coupling.
No original KTR components (purchased parts) are used.
Old/already worn out spiders or spiders stored for too long are used.
Maintenance intervals are not observed.

ROTEX®is a low-maintenance coupling. We recommend to perform a visual inspection on the coupling at least
once a year. Please pay special attention to the condition of the coupling spiders.
Since the flexible machine bearings of the driving and driven side settle during the course of load, inspect the
alignment of the coupling and re-align the coupling, if necessary.
The coupling components have to be inspected for damages.
The screw connections have to be inspected visually.
!
Having started up the coupling the tightening torques of the screws have to be inspected
during the usual inspection intervals.
A basic requirement to ensure the readiness for use of the coupling is a stock of the most important spare parts
on site.
Contact addresses of the KTR partners for spare parts and orders can be obtained from the KTR homepage at
