Complementary to the all-round couplings RATO S and RATO S+, the high-torque flexible couplings RATO R and RATO R+ have been specially designed for use in installations requiring a high level of torsional flexibility and misalignment capacity. Inherent features of the design include a high dynamic load capacity and good rotational dynamic properties due to the low rotating inertias. The area of application is primarily in high-speed main/PTO systems driven by a diesel engine or electric motor. In the low- to middle-torque range where the handling and installation of a complete element are practicable, the couplings RATO R and RATO R+ are an additional alternative. With the introduction of the ACOTEC range, smaller sizes with higher power density provide a good price-performance ratio.

Benefits

• High-torque flexible coupling with various torsional rigidities and element designs ensure excellent coordination of the torsional vibration and therefore the availability of the drive system.
• Flexible coupling with low rotating masses, optimized for the trend towards high-performance and high-speed engines
• Maximum flexibility in providing a solution considering that it can be easily integrated into different systems.
• Vibration damping coupling with soft circular diaphragms provides effective protection for the shaft bearing with axial vibration decoupling.
• Excellent noise damping characteristics by avoiding direct metallic contact.
