Elastic Couplings with Nylon Ring

Tramec GN couplings are made up of two toothed steel bushings, connected by a nylon ring with internal toothing. A snap ring at the center of the hole prevents axial displacement. GN couplings are only available with shaft grooves (hole, key, and dowel) machined to the sizes listed in the table.
GN couplings are recommended for transmission of moderate torques at high-speed rates (input shafts).
The maximum allowed ambient temperature is 70°C.
