ACT7NN Reich Arcusaflex Drive Coupler

The ACT7NN Reich Arcusaflex Drive Coupler is a heavy-duty flexible coupling designed for demanding industrial power-transmission applications where drivetrain protection, vibration control, and long-term reliability are critical. As part of the Arcusaflex ACT-series, the ACT7NN is engineered to transmit substantial torque loads while absorbing torsional shock and compensating for shaft misalignment during normal equipment operation.

Reich Arcusaflex couplers are widely specified in rotary screw air compressors, generator sets, pumps, and engine-driven machinery due to their proven elastomeric construction and long service life. The ACT7NN functions as a mechanical buffer between the prime mover and the driven component, helping reduce the transmission of harmful vibration and transient torque spikes into the drivetrain.

This coupling is intended for continuous-duty service in industrial environments where vibration, load variation, and thermal expansion are common operating conditions.

Functional Design and Performance

The ACT7NN 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 fluctuations before they are transmitted into the drive system.

In applications such as rotary screw compressors and generator sets, torsional oscillations are a leading cause of bearing wear, shaft fatigue, and alignment issues. The elastomer element within the ACT7NN 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 operation, helping maintain proper alignment without introducing excessive mechanical stress into the system.

Performance Advantages

The ACT7NN Reich Arcusaflex Coupler delivers consistent, vibration-controlled torque transfer that enhances reliability throughout the drive system. By isolating torsional vibration, it reduces mechanical noise, minimizes wear on bearings and shafts, and helps prevent 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, stable 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.
