Product catalog summary
Introduction
Flender Mechanical Power Transmission Couplings, available through jbj Techniques, offer a variety of coupling types including flexible, highly flexible, torsionally rigid, and backlash-free options. These couplings are designed for diverse applications, such as rail vehicles, and are tested for reliability and safety.
Flexible Couplings
Flender's flexible couplings, including N-EUPEX, RUPEX, and N-BIPEX, cater to a wide range of applications with rated torques from 12 Nm to 1,300,000 Nm.
Highly Flexible Couplings
ELPEX, ELPEX-B, and ELPEX-S couplings provide high flexibility, damping capacity, and low torsional stiffness, suitable for machines with non-uniform torque characteristics, with rated torques from 24 Nm to 90,000 Nm.
Torsionally Rigid Couplings
ZAPEX gear couplings and ARPEX all-steel couplings are designed for high torque transmission, with rated torques from 92 Nm to 7,200,000 Nm, suitable for specific shaft misalignment, temperature, and torque conditions.
Backlash-Free Couplings
BIPEX-S and SIPEX couplings offer vibration-damping and electrically insulating properties, with high torsional stiffness for isogonal torque transmission, with rated torques from 0.1 Nm to 5,000 Nm.
FLUDEX Couplings
FLUDEX couplings are hydrodynamic fluid couplings that limit starting and maximum torque in the drive train, serving as overload protection and aiding in motor starting.

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, tested...

Torsionally Flexible Couplings Rupex Series Introduction Function The motor torque is transmitted to the hub on the drive side via the shaft-hub connection, which is mostly designed as a keyway connection. With the aid of elastomer elements mounted on steel pins, the torque is conducted to the hub on the output side. The hub on the output side further transmits the torque to the driven machine or a gear unit located in between. Because of the primarily compression-loaded elements, the coupling has a progressive torsional stiffness. Technical specifications Rated Torque for Buffer Type Size Power...

Torsionally Flexible Couplings Rupex Series Introduction Torsional Stiffness and Damping The values stated in the previous table on page 4 apply to a capacity utilization of 50 %, an excitation amplitude of 10 % TKN with the frequency 10 Hz and an ambient temperature of 20 °C. The dynamic torsional stiffness is load-dependent and increases in proportion to capacity utilization. The following table shows the correction factors for different rated loads.
