General features of Nor-Mex couplingsNor-Mex

General features of Nor-Mex flexible couplings:

Torsinally flexible, maintenance-free

Damping vibrations, fine dynamic properties,

Axial plug-in, fail safe,

Compact design, small moment inertia,

Can be combined with various sizes of brake drum anddisc, which must be placed at the shaft ends with highermass moment of inertia,

The maximum brake torque must not exceed themaximum torque of the coupling.

* The torpue values are based on the elastic strength of the flexidle elements.

Values in the cataloque are given for the quality Pb72.

in case of using Nor-Mex Combination G together withPb82 elements, the max torque TkGmax given in tablecan be transmitted.
