Flender Mechanical Power Transmission Couplings available from jbj Techniques FLUDEX couplings are hydrodynamic ﬂuid couplings which operate on the Fottinger principle. FLUDEX® couplings limit starting and maximum torque in the drive train and, through the property of rotational slip, serve as an aid to starting the motor, as overload protection in the event of fault and for isolating torsional vibration. To compensate for shaft misalignment, the FLUDEX® coupling is combined with a displacement coupling e.g. of the N-EUPEX® type. Railway Couplings Couplings for rail vehicles developed,...

Torsionally Flexible Jaw Couplings N-Bipex Series General Information An additional size marking has been provided on the outer surface of the coupling element to be able to determine the size of the N-BIPEX even when it is in the assembled state without having to use any additional aids. The coupling is suitable for use at ambient temperatures between -50 °C and +100°C without any restrictions on the rated torque as a result of temperature factors. Function The torque is transmitted to the hub at the drive end via the shaft-hub connection, which is mostly designed as a keyway connection,...
