ACH11SN Reich Arcusaflex Drive Coupler | OEM Flexible Industrial Coupling

The ACH11SN Reich Arcusaflex Drive Coupler is a heavy-duty flexible coupling designed for industrial and power-transmission applications where torque stability, vibration control, and drivetrain protection are critical. As part of the Arcusaflex ACH-series, the ACH11SN is engineered to handle substantial torsional loads while maintaining smooth, reliable power 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 ACH11SN functions as a mechanical buffer between the prime mover and the driven component, absorbing torsional shock and compensating for minor shaft misalignment that occurs during normal operation.

This coupling is designed for continuous-duty operation in harsh industrial environments where vibration, load variation, and thermal expansion are common.

Functional Design and Performance

The ACH11SN 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 leading cause of bearing wear, shaft fatigue, and alignment issues. The elastomer element within the ACH11SN 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 naturally occur during operation, helping maintain alignment without introducing excessive stress into the system.

Performance Advantages

The ACH11SN 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 ACH-series coupling helps preserve original equipment performance, alignment accuracy, and operational efficiency.
