FLENDER couplings - flexible, comprehensive, available worldwide

As the worldwide largest manufacturer of mechanical couplings, with more than 80 years of experience, Siemens ensures that machine shafts are safely connected in the industrial sectors we serve – worldwide. The high-quality industrial couplings are very well suitable for the use in many fields of application, many of them even in potentially explosive atmospheres. The product range covers couplings of a torque range from 10 up to 10,000,000 Nm.

FLENDER couplings stand for highest reliability, low maintenance, and low investment and life-cycle costs. Even as individually adapted solutions, they are convincing because of their highest product quality and long service life.

Flexible couplings N-Eupex

Due to their torsional flexibility N-EUPEX couplings offer the possibility of moving critical torsional vibrations from the operating area of the mechanical equipment in such a way that no negative effects on the drive train are to be expected. N-EUPEX couplings are made of high-quality cast iron. The flexible elements made of synthetic rubber (buna N) are available in different degrees of hardness for many applications. Metal pins and flexible elements are so designed that no wear occurs when properly fitted.

Flexible couplings Bipex

BIPEX couplings are used for all mechanical engineering purposes where an uninterrupted transmission of power is required even in the presence of unavoidable shaft misalignments. BIPEX couplings are particularly suitable for the connection of driven machines with uniform torque loads. They have a very low circumferential backlash and can be used for any inclined mounting position.

Flexible couplings Rupex

RUPEX couplings are used as flexible compensating couplings in all applications requiring a reliable transmission of torque under harsh operating conditions. The conical seats of the buffer pins facilitate mounting and guarantee maintenance-free operation. The optimized shape of the barrelled buffers allows simple plug-in assembly and low circumferential backlash. Many type variants are offered, e. g. with brake disk, axial play limiting device, or brake motor couplings.

Highly flexible couplings Elpex-B

Owing to its low torsional stiffness and damping property the ELPEX coupling is very well suitable for connecting machines with a considerably non-uniform torque characteristic. Types with a fail-safe device between the flexible rings ensure emergency operation if the flexible rings are destroyed. ELPEX couplings are available in 12 sizes for torques from 1,600 Nm up to 90,000 Nm.

Torsionaly rigid couplings Arpex

ARPEX all-steel couplings have proved themselves for over 30 years in all fields of engineering where reliable and maintenance-free transmission of torque is required in the case of shaft misalignments. The compact and rugged design ensures a long service life and a high degree of operational reliability.

Torsionaly rigid couplings Zapex

ZAPEX gear couplings are particularly suitable for rough operating conditions as occur, for example, in metallurgical engineering or in the cement industry.  In addition, ZAPEX couplings stand out due to their power capacity combined with compact design.

Hydrodynamic couplings Fludex

The FLUDEX coupling is a fluid coupling on which the coupling parts on the input and output side are not mechanically connected and thus resistant to wear. FLUDEX couplings limit the starting and the maximum torque in the drive train and serve as starting aid for the motor, as overload protection in case of malfunction, and for torsional vibration separation. Four series of FLUDEX couplings are offered with various types and sizes designed according to the modular construction system and for power ratings up to 2,500 kW.
