FLENDER Standard Couplings
Torsionally Rigid All-Steel Couplings - ARPEX Series
General information
■ Overview
Thanks to a large number of standard components ARPEX couplings can be combined to make many different types. In this
way, standard types can be used with many drives.
ARPEX couplings can withstand temperatures between
–40 °C and +280 °C in operation. On request, they can also be
specially equipped for use in other temperature ranges.
ARPEX coupling optionally suitable for potentially explosive
environments.
Complies with Directive 94/9/EC for:
II 2G T2/T3/T4/T5/T6
–40 °C % Ta % +230 °C/+150 °C/+85 °C/+50 °C/35 °C

ARPEX couplings have proved themselves for over 30 years in
all areas of technology where reliable, maintenance-free torque
transmission is required. ARPEX couplings link machine shafts
and compensate for shaft misalignments, while generating only
low restorative forces. Thanks to the use of spring steel plates
and backlash-free screw connections, ARPEX couplings are torsionally rigid and backlash-free. All ARPEX coupling components are manufactured from high-quality steel. Robust, compact construction guaranteeing a high level of operational
reliability and a long service life is therefore possible. High-precision production ensures that at speed in the assembled condition only low forces act on the machine parts connected to them.
ARPEX couplings can be used for both directions of rotation and
are thus also suitable for reverse operation.
ARPEX couplings are not subject to wear and, if correctly designed, assembled and installed, can be expected to have an
unlimited service life. With most types the intermediate spacer
can be fitted radially without having to move the driving and
driven machines.
II 2D T 120 °C –40 °C % Ta % +70 °C
I M2
To meet the high quality demands made of ARPEX couplings,
the development and manufacture of ARPEX couplings is integrated into a certified quality management system in accordance with the requirements of DIN EN ISO 9001.
Type approval for use of ARPEX couplings in shipbuilding has
been issued by the following classification societies: American
Bureau of Shipping (ABS), Det Norske Veritas (DNV), Germanischer Lloyd (GL) and Lloyd's Register of Shipping. Product certification to GOST-R for the Russian market has already been obtained.
■ Design
ARPEX couplings are manufactured completely from steel.
Torque is transmitted by means of torsionally rigid, flexible
plates. The plates are held together by a sleeve and ring to form
a compact plate pack. This ensures easy, operationally safe installation. Two plate packs fastened alternately to the flanges
permit compensation of shaft misalignments in an angular, radial
and axial direction. On coupling types with a single plate pack
only angular and axial misalignments are possible.
Plate pack
The flexible elements in an ARPEX coupling take the form of
plate packs. The individual, thin plates are held together by a
socket and ring to form a compact plate pack. The picture below
shows the structure of a ring plate pack.
Materials
All coupling parts like hubs, spacers and flanges are manufactured from high-grade steel; the plates are made from stainless,
hard-rolled CrNi spring steel. Bolts and nuts are of quality 10.9
or 10.
Application
ARPEX couplings are available as a catalog standard from
92 Nm to 1450000 Nm and are divided into various series. Because of this series diversity, ARPEX couplings meet most
torque and speed requirements as a universal coupling solution
in general mechanical engineering. The individual series and
their corresponding possible applications are described in full in
the following sections.

Close-fitting bolt
Up to bolt size M22, the plate pack screw connection on ARPEX
couplings is in the form of a close-fitting bolt connection. After
that the patented conical screw connection is used. The decisive advantage of this screw connection is considerably simplified fitting. The use of an hydraulic fitting tool is no longer necessary. All sizes can be fitted with a torque wrench.
A further feature of the conical screw connection is the genuine
positive connection resulting in high centering accuracy and,
thus, a high balancing quality. Material: High-grade quenched
and tempered steel.

Torsionally Rigid All-Steel Couplings - ARPEX ARS-6 Series
General information
■ Overview
Coupling can be designed for potentially explosive
environments.
6
■ Benefits
ARPEX couplings of the ARS-6 series are outstanding for their
versatility. Most standard components are available from stock,
resulting in short delivery times. Their use in potentially explosive
environments in accordance with Directive 94/9/EC is possible.
■ Application
ARPEX couplings of the ARS-6 series are a versatile coupling
solution which thanks to standard modular components can be
used for most drive requirements at a low to medium speed.
Torques of between 170 and 106000 Nm can be transmitted at
a permitted angular misalignment of 0.7°. The open flange form
is regarded as very easy to fit and has easily accessible screw
connection points. On most types, the intermediate spacer can
be radially fitted without moving the connected units.
Main areas of application for the ARS-6 series:
• Paper-making machines
• Printing machines
• Compressors
• Pumps
• Fans and blowers
• Film and foil machines
• Generators
• Presses
• Metalworking machines
• Conveyors
• Crane systems
• Textile machines
• Plastics processing machines
• Centrifuges

Torsionally Rigid All-Steel Couplings - ARPEX ARS-6 Series
General information
■ Design
The classic design of an ARPEX couplings of the ARS-6 series is
shown in the following illustration. The plate packs are bolted alternately between the flanges of the coupling hubs and the intermediate spacer. Up to size 280-6 close-fitting bolts and from size
305-6 conical screw connections are used for fastening. A large
number of intermediate spacer and shafts, hubs and flanges
can be combined and thus cover a large number of possible
drive requirements.

All coupling types can be very easily combined with further standard components in the ARPEX modular system. Jumbo hubs
are used to permit larger maximum bores.
Clamping hubs transmit torque by friction without the use of parallel keys.
F, D and C flanges offer many different possibilities for flange
connection.
The coupling parts of the ARPEX ARS-6 series are machined on
all sides. Exceptions are H and Z spacers and intermediate
shafts. The spacers are delivered with unmachined, primed
spacer tube.
Higher torques and maximum speeds with similar coupling outer
diameters DA can be achieved with the ARPEX ARC-8/-10 series.
Further application-specific coupling types are available in selection module x.CAT at www.flender.com. Dimension sheets
and further information are available on request.

The permitted shaft misalignments "Ka, "Kr and "Kw are maximum values and must not occur at the same time (see following
table).
The permitted shaft misalignment "Kr for types NHN, NZN and
NWN applies to a coupling with shaft distance S = 1000 mm.
For other shaft distances, the permitted radial misalignment can
be determined with the following formula:
"Kr = (S – S1) # tan ("Kw).
The shaft distance S is shown in the table for the type.
TKmax permitted only five times per hour.

The values for torsional stiffness apply to the complete coupling.
In the case of types NHN and NZN to a coupling with shaft distance S = 1000 mm. In the case of type NWN, the torsional stiffness applies to a coupling without intermediate or torsion shaft.
The torsional stiffness of the plate packs applies to the rated
coupling torque TKN. To determine the torsional stiffness for a
specific operating point, e.g. for calculating torsional vibration,
the manufacturer must be consulted.

J hub
■ Selection and ordering data
J hubs or jumbo hubs are used where the shaft diameter is greater than the maximum bore diameter of the N hub. Because of the
larger hub core diameter “ØND1”, the J hub cannot be used as a B hub, i.e. the hub core diameter is greater than the inside diameter
of the spacer tube and cannot project into the spacer. The J hub can be combined with any spacer.

FLENDER Standard Couplings
Torsionally Rigid All-Steel Couplings - ARPEX ARS-6 Series
Further hubs and flanges
Clamping hub
■ Selection and ordering data
Standard clamping hub types 124 and 125 can be combined
with any spacer. It should be noted that the clamping hub can
be used only as an N hub (hub core outside). Clamping hub as
“B hub” (hub core in spacer tube) on request. Transmissible
torque and maximum bore diameter are smaller on a B hub variant than stated below.
Transmissible torque
Function
Fitting clearance and surface roughness
ARPEX clamping hubs transmit torque with the aid of a flexible
press fit. By pulling the clamping ring on by means of the tightening screws the necessary surface pressure is applied in the
“shaft/hub” contact area. After the tightening operation the
clamping ring lies up against the clamping hub. The gap dimension between the clamping hub and the clamping ring is then
zero. This has the effect that even with repeated fitting and dismounting the balancing condition is maintained (no wobble effect). Clamping hubs can be clamped as often as required. It
must be ensured that the taper surfaces are adequately lubricated.
The transmissible torques take into account the maximum fitting
clearance and maximum surface roughness. For other shaft tolerances reduced torques or other bore tolerances must be used.
The surface roughness of the shaft should be % Ra = 1.6 *m.
The shaft tolerance must be specified in the order.
To specify, -Z must be added to the product code and the
order code Y26 with plain text specification of the shaft
tolerance for D1 must be added as well. The fit pairing G6/h6
should be used wherever possible.

FLENDER Standard Couplings
Torsionally Rigid All-Steel Couplings - ARPEX ARC-8/-10 Series
General information
■ Overview
Coupling can be designed for potentially explosive
environments in accordance with 94/9/EC.
■ Benefits
ARPEX couplings of the ARC-8/-10 series are outstanding for
their robust construction. They have been optimized for high
torques combined with high speeds. The patented conical
screw connection ensures reliable torque transmission by a true
positive fit and is designed to be extremely easy to fit. Couplings
can be designed for potentially explosive environments in accordance with 94/9/EC.
■ Application
ARPEX couplings of the ARC-8 and ARC-10 series are outputand speed-optimized coupling solutions. Power transmission is
by means of patented conical screw connections and plate
packs of the octagonal and decagonal types. Torques of between 8.5 and 1450 kNm can be transmitted at a permitted angular misalignment of 0.2° to 0.4°. The closed flange shape and
a compact construction permit high peripheral speeds and high
speeds. On most types, the intermediate spacer can be radially
fitted without moving the connected units.
Main areas of application for the ARC-8/-10 series:
• Paper-making machines
• Printing machines
• Compressors
• Fans and blowers
• Generators
• Presses
• Conveyors
• Crane systems
• Pumps
• Mills
• Rotary furnaces
• Stirrers

The permitted shaft misalignments "Ka, "Kr and "Kw are maximum values and must not occur at the same time (see following
table).
The specified, permitted shaft misalignment "Kr for types
NEN/NHN and MFEFM/MFHFM applies to a shaft distance of
S = 1000 mm (ARC-8) or S = 1500 mm (ARC-10).
The permitted shaft misalignment "Kr for types NEN and NHN is
calculated as follows: "Kr = (S – S1) # tan("Kw).
The permitted shaft misalignment "Kr for types MFEFM and
MFHFM is calculated as follows:
"Kr = (S – S1 – 2 # BF) # tan("Kw).

The values for torsional stiffness apply to the complete coupling.
In the case of types NHN and MFHFM to a coupling with shaft
distance S = 1000 mm (ARC-8) or S = 1500 mm (ARC-10). The
torsional stiffness of the plate packs applies to the rated coupling torque TKN. To determine the torsional stiffness for a specific operating point, e.g. for calculating torsional vibration, the
manufacturer must be consulted.
TKmax permitted only five times per hour.

FLENDER Standard Couplings
Torsionally Rigid All-Steel Couplings - ARPEX ARC-8/-10 Series
Type BUB
Split intermediate spacer permits preassembly of the coupling
halves at the factory and easy final assembly by the customer
(optional).
Power transmission via patented conical screw connection.
The hubs are standard-manufactured from high-grade steel.
In the case of smaller bore diameters higher-grade material is
used, depending on the application (additional price).
Weights and mass moments of inertia apply to the entire
coupling with maximum bores D1/D2.
Ordering example:
ARPEX ARC-8 BUB coupling, size 270-8,
Bore 'D1 120H7 mm, with keyway to DIN 6885 and set screw,
Bore 'D2 130K7 mm, with keyway to DIN 6885 and set screw.

Torsionally Rigid All-Steel Couplings - ARPEX ARP-6 Series
General information
■ Overview
Coupling can be used for potentially explosive
environments in accordance with 94/9/EC.
■ Benefits
ARPEX couplings of the ARP-6 series are outstanding for their
application-optimized construction. The two types NAN and
MCECM have been specially designed for drives with uniform to
medium loads and at the same time meet the requirements of
API 610. The type MCECM with preassembled CEC intermedi-
ate unit can also be optionally designed to API 671. A special
catcher device serves to secure the intermediate spacer in the
event of plate breakage. Their use in potentially explosive environments in accordance with Directive 94/9/EC is possible.
■ Application
ARPEX series ARP-6 couplings have been specially developed
for pump drives and specifically for centrifugal pump drives.
Special care was taken to meet the requirements of API 610 and
API 671 (API = American Petroleum Institute). Power is transmitted via close-fitting bolts and nuts from size 310-6 with conical
screw connection and plate packs in hexagonal design. Torques
of between 100 and 17000 Nm can be transmitted at a permitted
angular misalignment of 0.7°. The closed flange shape and a
compact construction permit high peripheral speeds and high
speeds. The intermediate spacer can be fitted radially without
moving the connected units.
Main areas of application for the ARP-6 series:
• Centrifugal pumps
• Boiler feed pumps
• Propeller pumps
• Wing pumps
• Pipeline pumps
• Turbo compressors
• Screw compressors
• Turbo blowers
• Axial, radial blowers
• Rotary-piston blowers
• Fans

The values for torsional stiffness apply to the complete coupling.
The torsional stiffness of the plate packs applies to the rated
coupling torque TKN. To determine the torsional stiffness for a
specific operating point, e.g. for calculating torsional vibration,
the manufacturer must be consulted.

FLENDER Standard Couplings
Torsionally Rigid All-Steel Couplings - ARPEX ARW-4/-6 Series
General information
■ Overview
Coupling can be designed for potentially explosive
environments in accordance with 94/9/EC.
6
■ Benefits
ARPEX couplings of the ARW-4/-6 series are outstanding for
their large angular misalignment capacity of 3°. They were specially designed for drives where high misalignments which have
to be compensated for by the coupling are to be expected. The
intermediate spacer lengths are variable and are manufactured
to customer specifications.
■ Application
ARPEX couplings of the ARW-4/-6 series are used where large
misalignment capacities are required. In the paper-making machine industry, the ARW coupling has already proved itself as a
maintenance-free alternative to the cardan shaft. Torques of between 92 and 80000 Nm can be transmitted at a permitted angular misalignment of 3.0°. The intermediate spacer can be fitted radially without moving the connected units.
Main areas of application for the ARW-4/-6 series:
• Paper-making machines
• Wind power systems
• Traction drives
■ Design
The design of an ARPEX NHN coupling of the ARW-4/-6 series is
shown in the following illustration. The plate packs are bolted alternately between the flanges of the coupling hubs and the intermediate spacer. Up to size 292-4 close-fitting bolts and from size
324-4 conical screw connections are used for fastening. Up to
size 647-4 plate packs in rectangular design, from size 695-6 in
hexagonal design are used. The intermediate spacers are variable in length and are manufactured specifically to customer
specifications.

The radial misalignment "Kr applies to a type NHN coupling with
a shaft distance S = 1000 mm. The radial misalignment "Kr for
other shaft distances S is calculated as follows:
"Kr = (S – S1) # tan("Kw)
The permitted shaft misalignments "Ka, "Kr and "Kw are maximum values and must not occur at the same time (see following

The torsional stiffness values apply to the entire coupling with
shaft distance S = 1000 mm. The torsional stiffness of the plate
packs applies to the rated coupling torque TKN. To determine the
torsional stiffness for a specific operating point, e.g. for calculating torsional vibration, the manufacturer must be consulted.
TKmax permitted only five times per hour.

FLENDER Standard Couplings
Torsionally Rigid All-Steel Couplings - ARPEX ARF-6 Series
General information
■ Overview
Coupling can be designed for potentially explosive
environments in accordance with 94/9/EC.
■ Benefits
ARPEX couplings of the ARF-6 series are extremely short and so
suitable for drives with short shaft distances. They also serve as
self-aligning couplings for axial, angular and radial misalignment. The hubs are available both as pure clamping hubs for
smooth shafts and with parallel keyway for shafts with parallel
key. The variant with slit clamping hubs enables the delivery of
fully preassembled couplings. This means that the entire coupling can be dismounted and fitted without moving the connected units.
■ Application
ARPEX couplings of the ARF-6 series are designed for minimum
fitting spaces without having to sacrifice the advantages of the
two-joint coupling. It is thus possible to compensate for both axial and angular as well as radial misalignment. By using halfshell clamping hubs, the coupling can be radially freely dismounted. Power is transmitted via hexagon socket head cap
screws and close-fitting bolts with nuts and ring plate packs in
hexagonal design. Torques of between 120 and 6100 Nm can
be transmitted at a permitted angular misalignment of 0.7°.
Main areas of application for the ARF-6 series:
• Film stretching machines
• Machines in the cellulose industry
• Machines in confined fitting situations
■ Design
The two plate packs form a unit with the adapter disk and are
screwed together with close-fitting bolts and nuts at three points.
The alternate connection of this intermediate unit with the
flanges of the split coupling hubs is achieved by means of short
hexagon socket head cap screws at further three points. The
hubs are designed as axially slit clamping hubs with a half-shell.
For larger bores these can be manufactured as jumbo hubs.
Optionally, the hubs are also available without parallel keyway.
