The RATO S, manufactured by VULKAN COUPLINGS®, is specifically designed as a torsionally adaptable rubber connection that supplies improved radial, axial and angular shaft movement of the linked machinery. Its responsive and firmly reinforced engines can send loaded elements into shear with a ready to use torsional stiffness and damping factors it can supply to tune the torsional vibration performance of the system drive. In addition, it is also distinguished in the vital technical data it's better execution.
