ACT3NT Reich OEM Drive Coupler

The ACT3NT Reich Arcusaflex Drive Coupler is a torsionally flexible, maintenance-free coupling engineered for demanding industrial and power generation applications. Part of Reich-Kupplungen’s proven Arcusaflex ACT series, the ACT3NT is designed to transmit high torque while isolating vibration and compensating for shaft misalignment between the prime mover and driven equipment.

This coupling is commonly used in rotary compressors, engine-driven generators, pumps, and heavy machinery where smooth power transfer and mechanical protection are critical. Its reinforced elastomer element and precision-machined steel components ensure dependable performance in continuous-duty environments with fluctuating loads.

Key Features and Benefits

• Authentic Reich Arcusaflex OEM Component – Manufactured to Reich-Kupplungen engineering and quality standards.

• High Torque Capacity – Designed for demanding industrial and power generation drive systems.

• Torsionally Flexible Design – Dampens vibration and absorbs shock loads during startup and load changes.

• Misalignment Compensation – Accommodates angular, axial, and parallel shaft misalignment.

• Maintenance-Free Operation – No lubrication required; long service intervals reduce downtime.

• Durable Elastomer Construction – Resistant to oil, heat, and fatigue in harsh operating conditions.

• Balanced Performance – Helps reduce noise, bearing wear, and shaft stress across the drive train.

Functional Design and Performance

The ACT3NT Arcusaflex Coupler consists of two steel flanges bonded to a high-performance rubber elastomer element. This design allows the coupling to act as a torsional spring, smoothing rotational energy and preventing vibration from transferring between connected components.

In compressor and generator systems, torsional vibration can lead to premature bearing failure, cracked housings, and alignment drift. The elastomer element in the ACT3NT absorbs these oscillations, protecting the motor, engine, and driven equipment from mechanical damage.

The coupling also compensates for thermal expansion and installation tolerances, maintaining proper alignment during operation. This makes it particularly effective in enclosed generator housings and compressor frames where temperature changes are common.

Applications and Compatibility

The ACT3NT Reich Arcusaflex Drive Coupler is widely used in:

• Rotary screw air compressors

• Engine-driven generators and alternators

• Industrial pump and motor assemblies

• Hydraulic power units

• Blowers, fans, and mechanical drive systems

This coupler is suitable for both OEM installations and service replacements where Arcusaflex ACT-series couplers are specified. It is commonly used in continuous-duty equipment that requires reliable vibration control and stable torque transmission.

Performance Advantages

The ACT3NT Arcusaflex Coupler provides an optimal balance between torque transmission and vibration isolation. Its elastomer formulation is engineered to handle high cyclic loads while maintaining flexibility, ensuring long-term durability in industrial environments.

Compared to generic flexible couplers, the ACT3NT delivers superior damping characteristics and more consistent alignment retention. This results in reduced mechanical wear, quieter operation, and improved reliability for compressors, generators, and other rotating equipment.

Using a genuine Reich Arcusaflex coupler also ensures correct material hardness and internal geometry, which are critical for preventing resonance and excessive torsional stress.
