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 ele..
