ROTEX® torsionally flexible jaw couplings are elastomer couplings characterized by a compact design.

Despite 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.

Thanks to the elastomer (elastomer spider) between the coupling hubs of the jaw couplings shocks respectively torsional vibrations in the drive train are damped. The high temperature-resistant spider material T-PUR® (elastomer) is available in various degrees of hardness. The torsionally flexible ROTEX couplings are used in almost every range of general machinery and plant engineering.

Properties of torsionally flexible jaw couplings:

ROTEX shaft couplings consist of two hubs (aluminum or steel) and a spider (elastomer ring / cam ring) made of T-PUR® (elastomer). The different degrees of hardness of the T-PUR-spider allow to adjust the level of damping and torsional stiffness of the elastomer coupling. Possible in 3 options:

· 64 Shore D T-PUR® light green

· 92 Shore A T-PUR® orange

· 98 Shore A T-PUR® lilac

ROTEX couplings require few mounting space and thus enable easy assembly/disassembly. The numerous types provide for maximum flexibility and meet with the different mounting requirements through various types of hubs.
