The ACT6NN Reich Arcusaflex Drive Coupler is a heavy-duty flexible coupling designed for demanding industrial power-transmission applications where drivetrain protection and operational reliability are critical. As part of the Arcusaflex ACT-series, the ACT6NN is engineered to handle substantial torsional loads while maintaining smooth, controlled torque transfer between rotating shafts.
Reich Arcusaflex couplers are widely specified in rotary screw air compressors, generator sets, pumps, and engine-driven equipment due to their proven elastomeric design and long service life. The ACT6NN acts as a mechanical buffer between the prime mover and the driven component, absorbing torsional shock and compensating for shaft misalignment that naturally occurs during operation.
This coupling is designed for continuous-duty service in industrial environments where vibration, load variation, and thermal expansion are common.

Functional Design and Performance
The ACT6NN Arcusaflex coupler utilizes a resilient elastomer element combined with precision-machined metal components to create a torsionally flexible shaft connection. This design allows the coupling to isolate vibration and transient torque spikes before they are transmitted into the drive system.
In applications such as rotary screw compressors and generator sets, torsional oscillations are a primary cause of bearing wear, shaft fatigue, and alignment issues. The elastomer element within the ACT6NN reduces these forces, improving drivetrain stability and extending the service life of connected components.
The flexible construction also compensates for installation tolerances and thermal expansion that occur during normal operation, helping maintain alignment without introducing excessive stress into the system.
Applications and Compatibility
The ACT6NN Reich Arcusaflex Drive Coupler is commonly used in a wide range of industrial and power-transmission systems, including:
-
Rotary screw and piston air compressors

Performance Advantages
The ACT6NN Reich Arcusaflex Coupler delivers stable, vibration-controlled torque transfer that enhances reliability across the entire drive system. By isolating torsional vibration, it reduces mechanical noise, limits wear on bearings and shafts, and helps prevent costly downtime caused by premature component failure.
Compared to rigid couplings or generic flexible couplers, Reich Arcusaflex couplings are engineered with elastomer characteristics optimized for industrial drive requirements. This ensures predictable damping behavior, consistent torque transmission, and long-term durability under fluctuating loads.
Using the correct ACT-series coupling helps preserve original equipment performance, alignment accuracy, and overall operational efficiency.
