Product Overview
1
SINGLE TAPER DESIGN
SERIES RFN 7003
Straight-Thru Type
Straight-thru type is suitable for
recessing inside hubs. Design
allows for possible axial shifting of
components relative to the shaft,
so utilize this device where exact
positioning is not critical.
2
SERIES RFN 7006
Flange Type
Flange type is designed for
narrow hubs and fixes the hub's
position relative to the shaft. No
axial shifting occurs. Liberal
machining tolerances also make
this device ideal for sprockets,
gears and similar components.
DOUBLE TAPER DESIGN
SERIES RFN 7005
The heavy duty locking assembly
offers high torque transmittal in
a small space. Designed for
drums, larger components and
heavy shock loads, this device
also provides good concentricity
to hubs.
3
SERIES RFN 7009
This device is a lighter duty
version for lower torque
requirements without sacrificing
concentricity.

NOTES:
The values of T, p and p’ are based on lightly oiled
installation (coefficient of friction = 0.12)
Type RFN 7006 and 7006-IN locking assemblies require a
higher tightening torque than Type RFN 7003/7003-IN
units to compensate for friction between locking assembly
O.D. and hub bore during installation. Be sure appropriate
tightening torque TA from specification table is used.

Step 2:
Select a locking assembly for the determined shaft dia. (d) from
specification tables and check if corresponding max. transmissible
torque (T) meets the torque requirement.
If, however, torque is the primary requirement, then select the
needed torque (T) from same specification tables and find the
corresponding shaft diameter (d).
Note: Required peak torque should never exceed specified
transmissible torque (T).

Installation and Removal Instructions: Type 7003 and 7006
INSTALLATION
Since the torque is transmitted by contact pressure and friction
between functional surfaces, condition of contact surfaces and
proper tightening of the locking screws are important. Locking
Assemblies are supplied ready for installation.
1. Check if all contact surfaces, including screw threads and
screw head bearing surfaces are clean and lightly oiled. If
not, lightly oil these parts.
Do Not Use Molybdenum Disulfide, “Molykote” or any
other similar lubricants.
2. Back-off all locking screws by at least two turns. Take out 3
or 4 equally spaced screws and insert them into adjacent
push-off threads after first removing the protective plastic
caps (if included). Turn them in hand tight until they make
contact with part (b), see Fig. 3. This will keep parts (a) and
(b) spaced apart for easy insertion of Locking Assembly into
the hub bore, as illustrated in Fig. 3.
3. Slide Locking Assembly onto the shaft and into the hub bore
and bring them to desired position.
4. Remove the locking screws separating parts (a) and (b) and
return them to their original holes and cover again the tapped
holes with the plastic caps (if included).
5. Tighten locking screws gradually and in several stages to
specified tightening torque (TA) using diametrically opposite
tightening sequence, however, with following exception: The
two screws adjacent to the slit in part (a) should be torqued
one after the other to avoid possible distortion of the flange,
see Fig. 4.
6. After completing
installation, check
locking screws
again in a clockwise
or counter-clockwise
sequence and
make sure none of
the bolts can be
turned at specified
tightening torque.
It is not necessary to
recheck tightening
torque after
equipment has been
in operation.
Fig. 3
NOTE: SERIES RFN 7006 AND 7006-IN Locking Assemblies
require a higher tightening torque than Series RFN 7003 and
7003-IN units in order to compensate for friction between O.D.
of part (b) and hub bore during installation. Make sure correct
tightening torque (TA) per specification table is applied.
REMOVAL
1. Loosen all screws a few turns.
2. Remove plastic caps in part (a) (if included) and transfer
screws to all push-off threads.
3. To release connection, progressively tighten these screws in
diametrically opposite sequence except the two (2) screws
adjacent to the slit, which must be tightened one after the other.
4. Remove Locking Assembly.

Heavy Duty Locking Assemblies
SERIES RFN 7005 & 7009
DESIGN CHARACTERISTICS
’
These Locking Assemblies are of double taper design with self-locking
tapers and an integral pre-centering section. As the locking screws are
torqued up, the tapered rings are pulled towards each other translating
the screw clamp forces into predictable, radial contact pressures on
shaft and hub bore creating a mechanical shrink fit.
In contrast to conventional interference or shrink fits, the Locking
Assemblies are installed with initial clearance fits assuring easy installation, axial and radial adjustments.
The wide design of these units offers greater torque and bending
moment capacities and provides good pre-centering characteristics in
straight-thru bore installations with excellent concentricity.

shaft diameter (d).
NOTE: Required peak torque should never exceed specified
transmissible torque (T).
Step 3:
Determine recommended min. hub outside dia. (DN) for locking assembly selected from specification tables or calculate hub outside diameter
(DN) by using the following equation:
Hub Calculation:
DN = D x

For LOCKING ASSEMBLIES RFN 7005, 7009
INSTALLATION
Since the torque is transmitted by contact pressure and friction between
functional surfaces, condition of contact surfaces and proper tightening
of the locking screws is important. Locking Assemblies are supplied
ready for installation.
1. All contact surfaces, including screw threads and screw head bearing
surfaces should be clean and lightly oiled. If not, lightly oil these parts.
Do Not Use Molybdenum Disulfide, “Molykote” or any other
similar lubricants.
2. Back-off all locking screws by at least two turns. Take out at least 3
equally spaced screws and insert them into adjacent push-off threads
in front thrust ring ➂ and outer ring ➁ as shown in Fig. 7. This procedure will keep the tapers apart for easy installation of the locking
assembly. If the holes are covered with protective plastic caps remove
them first, of course.
Fig. 7 Installation and removal position
3. Place locking assembly on shaft and into hub bore to desired position.
Remove the screws from the push-off threads and screw them back
into the original threaded holes of the rear thrust ring ➀ as shown in
Fig. 8.
1 = Rear thrust ring
2 = Outer ring
3 = Front thrust ring
4 = Locking screw
4. Tighten locking screws evenly in several stages to specified tightening torque (TA), listed in table below or specification tables. Use diametrically opposite tightening sequence, however, with following
exception: The two screws adjacent to the slit should be torqued
one after the other to avoid possible distortion of the thrust rings, see
Fig. 9.
NOTES
a) Even tightening is best accomplished by turning each screw in
increments of approx. 90º.
b) For the final pass it is recommended to set the torque wrench by
approx. 5% over the specified tightening torque (TA) to compensate
for any possible setting.
5. After completing the final pass, it is important to make sure that the
torque wrench is set at specified tightening torque (TA). Now check all
locking screws in clockwise or counter-wise sequence. If no screw
can be turned any more, the installation is finished. There is no need
to recheck tightening torque after equipment has been in operation.
NOTE
Used Locking Assemblies must be cleaned, lightly oiled and
re-assembled as shown in Fig. 8. That means the slits of the front ➂
and rear ➀ thrust rings as well as the outer ring ➁ have to be lined
up and the clearance holes of the front and outer ring must be
opposite the threaded holes of the rear thrust ring.
Fig. 8 Tightening procedure position
REMOVAL
1. Loosen all screws a few turns.
2. Remove plastic caps located in front thrust ring ➂ (if included)
and transfer the locking screws into all push-off threads provided
in front thrust ring ➂ and outer ring ➁ as shown in Fig. 7.
3. To release connection, progressively tighten all screws in diametrically opposite sequence except the two (2) screws adjacent to the slit,
which must be tightened one after the other.
4. Remove Locking Assembly.

d
= nominal locking assembly I.D.
= shaft O.D.
D
= nominal locking assembly O.D.
= hub bore I.D.
L1, L, l =width dimensions, in relaxed condition
T
= maximum transmissible torque
p
= contact pressure between locking assembly
and shaft
p’
= contact pressure between locking assembly
and hub bore
TA
= required tightening torque per locking
screw (tighten with torque wrench)
DN = min. hub O.D. for single unit installation based
on hub material Y.P. as shown in table and
hub width B=1.5 L1 (c=0.8); for other hub
materials calculate hub O.D. per step 3 of
Selection Guide.
TR = Allowable maching tolerance
for shaft: use d + 0/–TR
for hub bore: use D – 0/+TR
Example: for 80 RFN 7009
required shaft size: 3.150" + .000/–.002"
required hub bore size: 4.724" – .000/+.002"
NOTES:
T x 24 (lbs)
Fax = axial load (thrust capacity) =
d
HOW TO ORDER:
Specify SIZE and SERIES
e.g. 80 X 120 RFN 7009
The values of T, Fax, p’ are based on lightly oiled
installation (coefficient of friction = 0.12)

Couplings with Ringfeder®
Shrink Discs®
Assure a totally backlash-free connection with precise synchronization
capability. Additional features:
Clearance fits for hub/shaft connection allow easy assembly and free
axial movement compensation during installation which eliminates
unwanted pre-loading or pre-stressing of the flexible elements.
ARCUSAFLEX® Flywheel
Couplings
BALL DETENT TORQUE
LIMITERS Type BD
Highly flexible, backlash-free, vulcanized rubber disc couplings
designed to couple the flywheel of
an internal combustion engine to the
shaft of the driven machine. Rubber
disc element accepts relatively high
angular, axial and parallel misalignments. Flange dimensions according to SAE J.620 standards.
These accurate ball/roller and socket
torque limiters are easily adjustable
for different torque settings. In the
event of an overload, personnel and
equipment are protected as these
devices disconnect mechanically
and make contact with a limit switch
that sounds an alarm or otherwise
shuts the drive down. Available in
various configurations and combinations with couplings.
In accordance with our established policy to constantly improve our products, the specifications contained herein are subject to change without notice.
Since our Engineers cannot be aware of all applications and cannot control all the factors that may affect the function of our products, our warranty applies to
