Flexible Couplings


Flexible FLENDER couplings are suitable for plug-in assembly and are easy to mount. The flexible elements compensate shaft misalignments and absorb moderate shock loads of motor or driven machines.

Standard couplings of a wide modular design range and application-related couplings in special design cover a multitude of applications.

Your Benefits

  • Reliable transmission of torque in case of shaft misalignment with low restoring forces

  • Suitable for vertical mounting position

  • Electrically insulating series are also available

  • Low degree of maintenance

  • Many series and sizes available ex stock at short term

  • Also available for use in potentially explosive atmosphere (acc. to 94/9/EC)

BIPEX Claw Coupling

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.

Examples of Application


Hydraulic drives

Geared motors

Pump drives

Axle drives

Torsionally flexible; high damping properties

Flexible fail-safe claw coupling

Very compact design; high power capacity

Very well suitable for plug-in assembly & assembly into bell housings

Available in stock ex 13 sized for a torque range from 13.5 Nm to 3,700 Nm

Type BWT with Taper bush for easy assembly and bore adaptation

N-EUPEX DS Pin Coupling

N-EUPEX DS couplings without fail-safe devices allow positive disconnection of input and output side upon failure of the flexible elements due to overload or wear. Then, the metal parts of the DS couplins can freely rotate in opposite directions. 19 sizes offer a wide range of applications. DS couplings are offered in a torque range between 19 and 21,200 Nm. Many types are available ex stock.

Examples of Application


Pump drives

Compressor drives

Fan & blower drives

Torsionally flexible & damping pin coupling without fail-safe device

Can be combined with many parts of the N-EUPEX range

Maintenance-free if used in explosive atmospheres

Can be used in potentially explosive atmospheres; certified acc. to 94/9/EC (ATEX 95)

N-EUPEX Pin Coupling

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 so that no wear occurs when properly fitted.

Examples of Application


Widely used in mechanical engineering, as high speed coupling on the motor side (e.g. pump, fan or compressor drives)

High torque couplings for the connection of gear unit and driven machine (e.g. mills)

Torsionally rigid and damping pin coupling to be used universally for compensating shaft misalignments

Maximum operational reliability, since fail-safe

Suitable for plug-in assembly and simplified replacement of elements in the type consisting of three parts

Dynamic adaptation by selection of elastomer hardness

Can be used in potentially explosive atmospheres; cert acc. to 94/9/EC (ATEX 95)

High degree of availability of parts ex stock

RUPEX Pin & Bush Coupling

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 allos 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.

Examples of Application





Screw pumps



Cement processing machines

Flexible fail-safe pin and bush couplings for muedium up to high torques
