FLANGE INSTALLATION
1. For the TAPER-LOCK® and QD anges, install bushing in
the ange per instructions included with bushing or nd the
instruction manuals at www.baldor.com.
2. Check the axial oat of the shafts. Position the shafts at the
mid-point of the oat. Where Limited End Float is required
or Sleeve Bearings are used, consult Mechanical Power
Transmission Support for application assistance.
3. Referring to Figure 1 and Table 1, observe the “B”
dimension for the coupling size being installed. Mount and
position the anges on the shafts so that dimension “B” is
achieved when the shafts are in their nal position.
For the TAPER-LOCK and QD anges, secure the ange
assembly to the shaft by positioning the assembly onto the
shaft allowing for small axial movement which will occur
during tightening procedure. Alternately torque hardware to
recommended torque setting. For the clearance t straight
bore (FBX) ange, tighten the set screws to values listed in
Table 2. Align anges using precision equipment such as
dial indicators or laser equipment.
If precision equipment is not available, scales, straight
edges, and calipers can be used as less accurate means of
alignment. If using a scale or calipers, refer to Figure 3 and
check the angular misalignment by measuring dimension
“B” at four places 90° apart. Adjust the equipment until
the four measurements do not vary more than value “C” in
Table 1. If using a straight edge, check the parallel offset
by laying the straight edge across the outside diameter of
the anges in four places 90° apart. The gap between the
ange and straight edge should not exceed 1/32” (0.79mm).
To achieve maximum coupling performance, align the
coupling as accurately as possible during initial installation.
4. Remove any anti-rust lubricants or oil from the grooved
side of the clamp rings. Loosen but do not remove clamp
ring screws until only one or two threads are engaged and
proceed to the section on exible element installation.

NOTE: Many sizes of PARA-FLEX elements are supplied with a
cardboard gauge to facilitate accurate flange spacing before
installing the rubber tire element. This gauge comes in the
box with the element. Gauges not supplied for PX40 and PX140
through PX320. Gauges should not be used for alignment
purposes.
FLEXIBLE ELEMENT INSTALLATION
1. Clean ange mounting area as well as surface that will
come in contact with the element with a solvent, such as
Xylene (Xylol), to remove grease, oil, wax, and dirt from
surfaces. Do not clean the element with the solvent. A
diluted soapy water solution may be applied to aid with
element installation.
2. Wrap exible element around anges as shown in Figure 5.
Make sure beads of element are fully worked down upon
the seats. To ensure proper seating, tap around the tire’s
outside diameter with a small mallet until split is closed.
Make sure element is evenly centered on the anges.
3. Hold split of exible element closed as shown in Figure
6. Tighten (nger tight) one or two screws 180° from split.
Using both hands, knead the tire pulling it toward the split.
Hold split closed and tighten (nger tight) the next two
screws farthest from the split. Repeat the procedure on
all remaining clamp ring screws. Use a torque wrench to
tighten each clamp ring screw in succession to the torque
specied in Table 1. Using a torque wrench, recheck all
clamp ring screw torque values before coupling operation.
4. Optional Procedure: Hold split of exible element closed as
shown in Figure 6. Tighten (nger tight) one or two screws
180° from split. Using both hands, knead the tire pulling it
toward the split. Hold split closed and tighten (nger tight)
the next two screws in a star or cross pattern as shown in
Figure 7. Repeat the procedure on all remaining clamp ring
screws. Use a torque wrench to tighten each screw to the
torque specied in Table 1. Using a torque wrench, re-
check all clamp ring screw torque values before coupling
operation.
5. Install coupling guards per OSHA or applicable
requirements. Guarding should be designed so that
coupling tyre will be contained within the guard in the
event that the coupling tyre is thrown from the coupling
assembly.

FLEXIBLE ELEMENT REPLACEMENT
Loosen all clamp ring screws. Grasp one end of exible element
at the split and peel off the anges. Clean clamping parts with a
solvent, such as Xylene (Xylol), to remove grease, oil, wax, and
dirt from surfaces. Do not clean element with solvent. Check
to see that only one or two threads of each clamp ring screw
are engaged. Re-align anges and install new exible element
according to the sections on ange installation and exible
element installation. When replacing clamp ring screws and
washers, use only SAE Grade 8 or ISO Class 10.9 screws and
hardened washers.
WARNING: The metal components of the coupling that clamp
the flexible element will operate properly only if the screws are
tightened properly. Tightening one screw to full torque before
proceeding to the next screw may cause excessive clamp ring or
flange deflection. To prevent clamp ring and flange deflection, the
screws must be evenly and gradually tightened to full torque.

1. Disassemble the clamp rings from the anges. Place the
external clamp rings on the shafts with the grooved side
facing the shaft end.
2. Check the axial oat of the shafts. Position the shafts at the
mid-point of the oat. Where Limited End Float is required
or Sleeve Bearings are used, consult Mechanical Power
Transmission Support for application assistance.
3. Referring to Figure 8 and Table 1, observe the “B”
dimension for the coupling size being installed. Mount and
position the anges on the shafts so that dimension “B” is
achieved when the shafts are in their nal position. Where
anges contain set screws, tighten to values listed in Table
2.
4. Remove any anti-rust lubricants or oil from the grooved
side of the clamp rings. Assemble internal and external
clamp rings to oating shaft anges and snug up clamp
ring screws. Slip internal piloted clamp rings onto the
turned down portion of oating shaft. Hub projection on
clamp ring should be toward oating shaft as shown in
Figure 8.
5. Position and support oating shaft assembly between
driving and driven anges. Make sure clamp ring pilot is
seated in ange counterbore. Assemble external clamp
rings to ange with screws. Tighten screws sufciently to
prevent movement between the parts.
6. Align anges using precision equipment such as dial
indicators or laser equipment. If precision equipment
is not available, scales, straight edges, and calipers
can be used as less accurate means of alignment. If
using a scale or calipers, refer to Figure 3 and check the
angular misalignment by measuring dimension “B” at
four places 90° apart. Adjust the equipment until the four
measurements do not vary more than value “C” in Table
1. Repeat the procedure at both ends of the coupling. To
achieve maximum coupling performance, align the coupling
as accurately as possible during initial installation.
7. Loosen clamp ring screws and proceed to Section II for
element installation.

Figure 9 - ATEX Certification
WARNING: These couplings are designed to operate with surface
temperatures below 100°C when properly installed and selected.
Excessive temperatures greater than 80°C is a result of an
abnormal operating condition caused by:
1. Improper installation - refer to installation manual for
proper procedures
2. Excessive misalignment - re-align coupling / shafts
3. Failure of the coupling element - replace elastomeric
4. Excessive speed - re-evaluate application and selection
5. Excessive vibration - determine source, re-evaluate
application
If applied in a Division 1 or Zone 1 environment, the excessive
temperature may cause ignition of hazardous materials.

In hazardous environments, DODGE elastomeric couplings
should not be considered as fail safe or “break-away” power
transmission devices. Overloads imposed to these devices
could cause irreparable damage, shall be considered an
explosive hazard, could create projectiles, and/or could cause
torque transmission interruptions. The coupling shall be
sized and used to the stated torque capabilities of the unit as
published in the DODGE PT Components Engineering Catalog.
Any assistance needed in selection shall be referred to an ABB
representative.
Additional Instruction for Safe Installation and Use
1. All rotating parts should be guarded to prevent contact with
foreign objects which could result in sparks, ignition, or
damage to the coupling.
2. Couplings should be periodically inspected for normal
wear, dust/dirt buildup or any similar scenario that would
impede heat dissipation.
3. Increasing levels of vibration and noise could indicate the
need for inspection, repair or replacement of the coupling
or element.
4. Electrical sparks are a source of ignition. To reduce the risk,
proper electrical bonding and grounding is recommended.
5. Overloading may result in breakage or damage to the
coupling or other equipment. As a result the coupling
could become an explosion hazard. Damaged coupling
components or elements must not be operated in
hazardous environment.
6. If thrust loading or axial movement is anticipated, The
DODGE PARA-FLEX coupling is the desired unit for use
as it has design capability of accepting this movement up
to 5/16”. Couplings are not intended to be used as thrust
bearing members.
7. Coupling guards should have a minimum of 2” clearance
over PARA-FLEX tire style couplings. (3” clearance
for PARA-FLEX style couplings greater than 16” outer
diameter.)
