Rated for operation at loads from 0.26 to 85kNm, and speeds from 8,000 to 3,600rpm, the Torsiflex range offers the benefit of a plug-in design that allows easy installation: the couplings can be installed and the flexible elements (disk packs) changed without disturbing adjacent machinery. Torsionally stiff and backlash free, the Torsiflex also incorporates an anti-flail feature. Moreover, it will accept significant levels of angular, radial and axial misalignment without any loss of operating performance. The units have no moving parts, so require no maintenance; and neither do they need lubrication; however the presenceof oil in the environment will not effect the operation of the coupling. The Torsiflex range can also be used in other environments where hostile working conditions are encountered. In these environments the couplings can be adapted using a variety of special materials and surface coatings. For hazardous environments, spark-free ATEX-rated versions of the couplings are available.
