Torsionally flexible jaw couplings and pin & bush couplings are suitable to offset axial, radial and angular displacements and dampen vibrations and torque shocks.
The vibration-damping properties are based on the flexible elements (elastomers) between the coupling hubs converting some of the energy of torque shocks into thermal energy.
Our range of flexible pin & bush couplings and jaw couplings (flexible couplings) includes torsionally flexible jaw couplings (ROTEX), torsionally flexible and fail-safe shaft couplings (POLY-NORM), torsionally flexible shaft couplings (POLY) and flexible pin & bush couplings (REVOLEX).
ROTEX® torsionally flexible jaw couplings are elastomer couplings characterized by a compact design.
In spite of low weights and mass moments of inertia of the elastomer couplings they are able to transmit high torques. The compact shaft couplings are characterized by a long service life and sound operating characteristics generated by allover machining.

A particular feature of the torsionally flexible and failsafe ROFLEX® shaft coupling is its short design resp. short DBSE [Distance Between Shaft Ends]. Short shaft distance dimensions allow for space-saving power packs.
The ROFLEX is approved for use in potentially explosive atmospheres. This is confirmed by the ATEX approval that applies for the European region and the EAC declaration which is intended for the Eurasian region. The ATEX type examination certificate and EAC certificate are specified in the menu item "Service".
ROFLEX® Failsafe
Shaft Couplings
POLY-NORM® shaft couplings are characterized by a compact design. The torque is transmitted via elastomers between the cams also serving to offset displacements and dampen shocks and torsional vibrations. Applications of our torsionally flexible, fail-safe shaft couplings:
POLY-NORM shaft couplings are used in almost all fields of mechanical engineering, here mainly in the pump industry (pump coupling).

POLY Torsionally Flexible,
Shear Type Shaft Couplings
REVOLEX are torsionally flexible, fail-safe pin & bush couplings that are mainly used in applications with high torques and drives subjected to shocks. They are specifically solid, fail-safe, compensate for any kind of shaft displacement while transmitting the torque reliably. The REVOLEX pin & bush couplings can be plugged in axially and are characterized by short dimensions.
These pin & bush couplings are generally equipped with hydraulically dismountable pins which means that special tools are not required for disassembly. The coupling components of the REVOLEX® pin & bush couplings are maintenance-free and allow for a smooth disassembly of elastomer rings along with pins in mounted condition.
