features
• Low mass
• Freedom from corrosion
• Good damping properties
• Low cost
• Reduced noise
• Design flexibility
The Huco FS Series is a 3-part, general purpose coupler
produced in 6 sizes. An advanced, high strength plastic
composite is used for the hubs to produce a durable, light
weight coupler suited to a wide range of industrial applications.
Simple to install, the FS coupler accommodates incidental shaft
offsets, absorbs shock loads and damps small amplitude
vibrations. It is impervious to moisture grease and oil and can
operate in the temperature range -50°C to +120°C.
A range of popular bore diameters, keywayed to ISO 773/774
(BS 4235), are standard in each size of coupler. Where
quantities can justify a modest investment in tooling, bores can
be moulded to customer's specification. The production
process readily allows economic manufacture of non-circular
bores. To suit varying operating conditions, the central drive
element can be specified in any of 3 standard materials. To gain
the maximum flexibility afforded by the 3-part construction,
hubs and elements are specified individually.
Standard hubs are supplied with matching steel key.

selection procedure
1. Determine service factor (SF) from table 1 and temperature
factor (TF) from table 2.
2. Multiply the power of the prime mover - PM(kW) - by SF and
TF to determine the Design Power - P(kW).
Design Power P = PM ×SF ×TF
3. Select a suitable element material, and enter the appropriate
section of table 3 with the rev/min, then read across until a
power equal to or greater than the Design Power is found.
The coupler size is given at the head of the column.
4. For intermediate speeds, the coupler size is determined by
consideration of the maximum torque capacity of the coupler
which varies according to the type of element selected.
Given the Design Power P(kW) and the speed N(rev/min) the
torque T(Nm) is given by:
T = 9550 ×P
N
Note: The torque figures given are the maximum for normal
running. FS couplers have capacity to meet normal
starting torque requirements in addition.

GEAR COUPLERS (SERIES NSG)
Huco nylon sleeve gear (NSG) couplers are compact and
efficient units capable of transmitting a high level of torque
relative to their size and weight. The couplers operate silently,
are electrically isolating and maintenance free. They are
marginally shock absorbent and easily installed in confined
spaces. Also directly interchangeable with some other makes.
features
• High torque capability
• Angular, parallel and longitudinal shaft misalignment
• Maintenance free
• Easy assembly
• Compact, lightweight design with low inertia
NSG couplers consist of two identical steel hubs with double
crowned teeth which engage in a moulded polyamide sleeve to
provide a double cardan coupling. The tooth form in
combination with the moulded nylon sleeve allows angular and
parallel misalignment of the two shafts, in addition to which the
hubs are free to move longitudinally to accommodate end float.

capability
The.couplers are suitable for full load operation at temperatures
ranging from –25°C to 100°C using a standard nylon sleeve,
and special sleeves are available for operating in temperatures
up to 125°C.
Friction between the mating teeth of the sleeve and hub is
minimised by the smooth surface finish. The large tooth contact
area also provides low contact pressure, reducing stress under
misalignment conditions, and the load is distributed near the
centre of the tooth for maximum strength.
selection
For even running applications eg. electric motor drives, select a
coupler with a nominal kW/rpm rating which equates to that of
the prime mover.
For other drives, eg. gearbox outputs I.C. engines, positive
displacement pumps or compressors, consider start-up loads,
impact loads and normal running loads and resolve each to a
torque value.
In general:
1. Nominal torque ratings allow for 82°C ambient, full
misalignment and/or maximum rpm.
2. Starting torque and braking loads should not exceed listed
maximum torque.
3. Intermittent, transient peak loads should not exceed three
times nominal torque.
4. Applications with uniform loading, well aligned shafts and low
speeds will allow for operation at maximum torque levels.

2-PIECE JAW COUPLERS

The HUCO 2-piece jaw coupler is moulded in polyamide. The
bores are sleeved with an insert-moulded aluminium extrusion,
keyed to resist turning. There is an all-plastics option on the
smaller sizes.
features
• Easily installed
• Angular, parallel & longitudinal compliance
• Corrosion resistant
• Ideal for blind assembly
• Low inertia
• Electrically isolating
• Non-magnetic
• Economic
The two-piece plastics construction offers simplicity of
installation and ready connection of two sub-assemblies. The
couplers will run submerged in most liquids and are reasonable
tolerant of polluted environments.
A 2-piece jaw coupler functions without an intermediary plastics
or elastomer insert. Clearances between adjacent jaws permit
relative lateral movement sufficient to compensate for nominal
misalignment between shafts. As a result the two halves plug
together without hindrance, generate low bearing loads in
operation and readily accommodate shaft end float.
Intended primarily for uni-directional loads, these couplers are
suitable for both horizontal and vertical drive applications in
ambient temperatures ranging –25°C to +80°C. Under these
conditions and when operating within their rated values, the
couplers will have a trouble-free life which can be improved
with a once-only initial application of oil or grease. Ambient
temperatures up to +100ºC can be sustained for short periods.
selection
For even running applications e.g. electric motor drives, select a
coupler with a nominal kW/rpm rating which equates to that of
the prime mover.
For other drives, e.g. gearbox outputs, I.C. engines, positive
displacement pumps or compressors, consider start-up loads,
impact loads and normal running loads and resolve each to a
torque value.
In general:
1. Select a Nominal torque value that exceeds the normal
running torque.
2. Starting torque and braking loads should not exceed listed
maximum torque.
3. Intermittent, transient peak loads should not exceed three
times nominal torque.
4. Applications with uniform loading, well aligned shafts and low
speeds will allow for operation at maximum torque levels..

Running Torque Nm
GM Flexible Jaw Couplers utilise the flexibility and resilience of
a polyurethane element between aluminium or cast iron hubs.
This combination allows high torque to be transmitted with little
or no backlash, even where there is significant angular and/or
parallel shaft misalignment.
A unique concave pocket in each hub eliminates edge pressure,
giving the element exceptional wear resistance and long service life.
Polyurethane elements are available with three hardness levels;
hard, standard and soft which exhibit different operating
characteristics as shown in Table 1. Other features of
polyurethane elements are:
• Resistance to oils, grease and many solvents.
• Good atmospheric and chemical resistance.
• Excellent shock and vibration damping.
• Operating temperature –40°C to 100°C
(Short duration max temp. 120°C)
selection procedure
1. Determine service factor (SF) from table 2 and temperature
factor (TF) from table 3.
2. Multiply the power of the prime mover - PM(kW) - by SF and
TF to determine the Design Power - P(kW).
Design Power P = PM ×SF ×TF
3. Select a suitable element material, and enter the appropriate
section of table 4 with the rev/min, then read across until a
power equal to or greater than the Design Power is found.
The coupler size is given at the head of the column.
4. For intermediate speeds, the coupler size is determined by
consideration of the maximum torque capacity of the coupler
which varies according to the type of element selected.
Refer to table 1.
Given the Design Power P(kW) and the speed N(rev/min) the
torque T(Nm) is given by:
T = 9550 ×P
N

• Keyless shaft - hub connection
• Ideal for heavy transmission
• Reduced machining costs
Keyless shaft-hub connection eliminates play between the shaft
and the hub distributes the power transmission on a limited
area only.
This allows savings in materials because the shaft diameters
can be designed smaller, making these ideal for heavy
transmissions, with overload or continuous reversing, or where
angular synchronisation is required, with several hubs mounted
on a single shaft.
Key:
TS= Screw tightening torque
T = Torque transmissible with tightening torque TS
F = Axial force transmissible with tightening torque TS
P = Hub surface pressure
Simple mounting and dismounting means easy and quick
changing of the hubs fitted on the shaft; the high pressure
between the contact surfaces helps avoid corrosion and, years
after installation, allows a quick removal of the hub.
