SHAFT COUPLINGS
How to select your flexible shaft couplings
The optimum choice of flexible coupling for any application is the result of a compromise between many
factors. Care should be taken to select a coupling which
meets the performance criteria at the minimum cost.
1. Decide if the coupling should be torsionally soft or
rigid. Torsionally soft types are generally less expensive.
2. Consider whether a small amount of backlash is
tolerable; a backlash-free coupling is usually
more expensive.
Torsionally soft with backlash
3. Calculate the required torque by multiplying the
running power and speed by the service factors
shown in the table below.
4. Make a provisional selection.
5. Check maximum speed and coupling dimensions
meet requirements.
6. Contact us to confirm price and delivery. Please give
the type number where possible. Our couplings
specialists are able to give advice where needed and
can offer other models.
Torsionally soft, backlash free
Torsionally rigid, backlash free
With backlash or backlash free?
Torsionally soft or torsionally rigid?
Couplings that have a one-piece construction or have
bolted joints are backlash free. These are useful for
precise positioning and to avoid wear on reversing
drives. Couplings with backlash tend to have lower
cost and are easier to install.
As a guide, couplings with rubber or plastic elements
can be considered as torsionally soft. Most metal couplings are rigid, but some such as Simplaflex have
quite low stiffness. A soft coupling may wind up 5° or
more at rated torque whilst a rigid one would twist as
little as 0.1°. Soft couplings are generally lower in cost.
Types of misalignment
Angular
This is usually present to some extent
on all applications, typical values 0.5°
– 2°. Sometimes higher values are
necessary.
Radial
Also known as parallel misalignment,
this is also nearly always present. A
well aligned installation might have
values below 0.20mm.
Axial
This can be considered as end float. It
is sometimes caused by thermal
expansion or is a result of machine
design.
Often a combination of all three types of misalignment is present.
Coupling maximum limits should not be used simultaneously.

All telescopic universal joints have splines made from
extruded steel grade C45 to UNI222. Precision
machined female bushes are made from the same
material.

Designed to protect the joint in severe or aggressive
environments, these gaiters are made from synthetic
rubber that is itself oil and acid resistant. They can be
used to allow permanent lubrication of the joint.
Note: 2 gaiters
are required for
double joints.

Type GESM
0.65 - 187Nm
Zero backlash
Variable torsional stiffness
Extremely fast assembly
Shaft tolerance h7
Hubs fully machined to give
precision fit with element
Torque capacity depends on shaft
size and model chosen
Type GESA with higher torques
available on request
Hubs
Coupling selection
Single screw split clamping hubs:
sizes 19/24 to 38/45 have aluminium hubs, size 42 are
made from steel. Supplied either rough bored or with
H7 finished plain bore.
The torque rating of the coupling is the lower of the
hub torque rating and the element torque rating from
the tables on the facing page.
Temperature range
Elements
Yellow element –40 to +90oC
Red element –30 to 90oC
Short term rating +120oC
Yellow, 92 shore A hardness for standard applications.
Red, 98 shore A hardness for higher torque, higher torsional stiffness, but reduced angular and radial misalignment capacity.

The barrel gear coupling is a flexible coupling having
two fully machined steel hubs with crowned barrelshaped teeth. These transmit torque by meshing with
the axially parallel involute gear teeth of the stabilised
6.6 super polyamid sleeve.
One complete coupling comprises
two hubs and one sleeve

Type 313.■
The HexaFlex coupling is very easy to mount. The flexible element can be removed without axial hub movement. The hubs can be aligned using either the outer
diameter or the machined faces. The hexagonal hub
form gives small overall dimensions for large bores and
permits a relatively large angular misalignment.
A complete coupling consists of
• 2 hubs (select required bores from table below)
• 1 off element and screw set

Angular misalignment
The angular misalignment of the spacer coupling is twice
the figure given for the HexaFlex standard coupling, that
is 4-10°.
3000
SIZES 48 TO 70
Description
The spacer is a drawn steel tube having a unique crosssection which precludes the use of keys and keyways. The
spacer is firmly fitted in the inner hubs and pinned to
ensure complete freedom from backlash.
The reinforced rubber discs provide for misalignment, and
are virtually indestructible.

Please note: all nominal torques are at maximum misalignment. For reversing applications the nominal torque must be divided by 2.
Screws
Carbon steel screws with black oxide finish are used in all couplings as standard. Stainless steel screws can be
supplied on request, but a lower coupling nominal torque applies.

Clamp hubs
Clamp hubs are available and eliminate the need for
keys and keyways. The design ■ .4 uses a single pinch
bolt principle, which is very quick and easy to mount
and maintain. Cone clamping models for high torques
are also available, please ask for details.
Note that maximum bore capacity is reduced compared to standard hubs. Inertias, stiffnesses and
weights can be considered the same as standard hubs.

Arcoflex type 314
Hubs mount externally or internally
(style Y)
Maintenance free
Pre-assembled disc packs
High speed capacity
Resistant to chemicals and ambients
from -40oC to +270oC
Selection options
Hubs
Spacers
Rated torques to achieve long life are
based on the actual misalignment of
the installation, 0.5o is best case, 1.3o
is worst case. Lower figures apply if
reversing.
Standard hubs to style X have larger
bore capacity but will not fit inside
the spacers. To achieve this use one
or two hubs of style Y.
Two spacer lengths are available,
long to Design 2.1 with length L2
and short to Design 4.1 with length
L8. Design 4.1 is more compact but
has lower misalignment capacity.
