© Siemens AG 2011 FLENDER Standard Couplings Flexible Couplings — N-EUPEX and N-EUPEX DS Series General information ■ Design N-EUPEX and N-EUPEX DS couplings consist of two hub parts mounted on the machine shafts. The coupling parts are connected positively by means of elastomer flexibles. On the twopart variant, the elastomer flexibles can be changed only if one of the coupled machines is moved. On the three-part variants, the bolted cam ring can be released and moved to enable the flexible to be changed without moving the coupled machines.

Technical data, prices and product codes on request. Brake disks EN-GJS-400 spheroidal graphite cast iron or S355J2G3 steel Brake drums Grey cast iron EN-GJL-250 Low-temperature application Shock loads in the drive caused by e.g. starting of drives with large masses to be accelerated (e.g. in fan drives) result in high component loads, particularly at low temperatures. For such applications a particularly robust coupling series must be selected. Of the flexible couplings, the RUPEX pin-and-bush coupling is especially suited for this.
