T4Gb X II 2DEx h IIICT85 °C ... 120 °CDb X I M2 Ex hMb X N-BIPEX couplings are torsionally flexible and are outstanding for their particularly compact design and low weight. N-BIPEX couplings are used in many areas of mechanical engineering. Their main area of use is in electric motor drives which are well aligned and have uniform torque loads, such as in hydraulic applications and in combinations with gearedmotors. N-BIPEX couplings consist of two identical hub parts which can be arranged as required on the shaft extensions to be connected. N-BIPEX couplings transmit the torque positively and are thus fail-safe. The curved design of the coupling element ensures that the N-BIPEX couplings have a perfect pressure distribution and this increases the elastomer lifetime. Benefits N-BIPEX couplings are suitable for horizontal, vertical and freely selectable mounting positions. They are able to absorb axial, radial and angular misalignment. 95 ShoreA– green » 64 Shore D – blue » Application The N-BIPEX coupling is available as a catalogue standard in 10 sizes with rated torques of between 12 Nm and 4650 Nm and is made of high-grade spheroidal graphite cast iron. The extremely high-performance coupling element materials are available from stock in three different Shore hardness with the following colours for ease of identification: The flexible coupling elements responsible for torque transmission and misalignment compensation are available in different Shore hardness. As a result of the good damping capability and by selecting the suitable stiffness, torque shock loads can be absorbed and the torsional vibration behaviour of the drive can be positively influenced. Different coupling element versions and ready-to-install hub parts are available from stock. 92 ShoreA– red » N-Bipex Series General Information Torsionally Flexible Jaw Couplings 1 #DriveLineHarmony
