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.

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.
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.

** Values apply to hubs with pilot bores.
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
2. Starting torque and braking loads should not exceed listed
3. Intermittent, transient peak loads should not exceed three
4. Applications with uniform loading, well aligned shafts and low
