Metall bellow coupling

The bellow couplings GSF have been designed and manufactured for all applications requiring excellent dynamic characteristics, necessary for high speeds, fast reversing and, at the same time, torsional rigidity with low inertia without compromising the high reliability. 

The coupling is made in three different and modular elements, in order to obtain high fl exibility in assembling and availability. 

The two shafts are connected to the bellow exploiting a simple mechanic system, easy and safe, by properly sized radial screws and without using bonding agents. In this way the coupling is able to operate and withstand high temperatures, up to 300 °C. The coupling allows the compensation of all possible misalignments between the two shafts, to be connected in accordance to the values indicated in the table, assuring an infinite number of working cycles.
