VULKAN RATO-S250 highly flexible coupling nominal torque is 25.0kNm with permitted rotational speed 1800rpm.
The VULKAN RATO-S250 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.
