VULKAN RATO-S190 highly flexible coupling nominal torque is 12.5kNm with permitted rotational speed 2300rpm.
The VULKAN RATO-S190 is a high flexible torsional rubber coupling, designed for demanding marine and industrial applications. It transmits torque through elastic rubber elements working in shear, effectively isolating torsional vibration and compensating for misalignments between connected machinery.
