Eflex coupling

Eflex RSA

The Eflex is a robust jawcoupling for compensating shaft misalignments, absorbing vibrations and transmit torque. The coupling is usually chosen for general machinery applications and ideal for pump- and screw compressordrives. A complete coupling consists of two hubs, one male and one female part, in combination with a set of elastomer elements. Standard we have the RSN (two-part coupling) and the RSA as a three-part coupling. The advantage of the RSA (three-part coupling) is the easy exchange of the elastomer elements after installation of the coupling.  Because the hub are made of ductile cast iron these couplings can also be used in low temperature applications. Torque of up to 30.000 Nm are stocked in 16 coupling sizes.

The elastomer elements normally have a hardness of 90 Shore A, other hardnesses are available on request. All executions have a surface treatment for corrosion resistance.
