Tsubaki presents at the Hanover Fair the NES series of its new generation of ultra-light "Real-Flex "couplings, The duralumin shaft couplings are not only characterized by low moments of inertia and high torsional rigidity.

The new clutch generation is based on the previous "Emer-Flex" clutch series of the manufacturer. To further develop the NES series real flex clutches for the ultimate disc clutch, the manufacturer optimized the force distribution in the central clutch disc using FEM. As a result, the NES series meets all conceivable requirements that are imposed on a disc clutch: The lubrication is eliminated and thus the couplings are maintenance-free, they run without play and offer due to the optimal torsional rigidity a high precision. Thanks to this outstanding performance, the Echt-Flex couplings reliably transmit torques and compensate for existing shaft misalignments.

The hub of the couplings is made of particularly resistant, lightweight extra super duraluminum and thus meets the theme of lightweight construction. The special hub geometry ensures a low moment of inertia. Therefore, this hub is ideal for applications that are greatly accelerated or decelerated, as is the case with servomotors, for example. Thanks to their high torsional rigidity and outstanding follow-up behavior, the Echt-Flex couplings are predestined for precision work. The clamping force on the shafts is ensured by the special geometry of the clamping connection and allows a high torque. The applied torque is transmitted completely free from friction.

With 56 designs and 3252 combinations of shaft bore diameters, the easy-to-mount NES series meets a wide range of requirements. In addition, the couplings meet the requirements of the RoHS directives as well as the regulations regarding dangerous chemical substances (JIG, PFOS and SVHC (15 substances)).

Real-Flex couplings are used, for example, in servo motor and spindle machine tools, in precision manufacturing machines, in industrial robots or in electronics and semiconductor manufacturing. They are available for shaft diameters from 4 to 50 mm, where they can transmit torques from 0,7 to 300 Nm.
