Rato Coupling

Clutch Engineering offers American Vulkan Rato couplings for marine propulsion systems, auxiliary drives, generators, and other industrial applications. These dependable couplings are compatible with both flexibly and rigidly mounted engines. They are torsionally flexible and can compensate for instances of radial, axial, and angular misalignment. These products are also designed to achieve maximum heat dissipation and a very long life. With advanced design and construction, torque is transmitted by elements loaded in shear. The different torsional stiffnesses and damping factors, available upon request, provide additional options for satisfactorily tuning the torsional vibration behavior of your drive system.

Torque range: 5,900 to 5,900,000 lb-ft (8 to 800 kNm)
Typical applications: Marine propulsion, auxiliary drives, generators
