ACT4SN Reich Arcusaflex Coupler Kit | Includes Coupling Element & Outer Flange

The ACT4SN Reich Arcusaflex Coupler Kit is a complete drivetrain solution consisting of the flexible elastomer coupling element and corresponding outer flange assembly. Designed for high-torque industrial applications, this kit provides both vibration isolation and secure mechanical mounting in one matched configuration.

Arcusaflex couplings are widely used in compressor packages, pump systems, and generator drives where torsional shock loads and vibration can significantly impact component longevity. The ACT4SN configuration offers controlled torsional flexibility while maintaining stable, backlash-controlled torque transmission.

By supplying both the coupling element and outer flange together, this kit ensures correct component pairing, proper fitment, and predictable performance under load.

Functional Design and Engineering Advantages

The ACT4SN Arcusaflex coupling utilizes a segmented elastomer element mounted between precision-machined metal components. Torque is transmitted through compression of the elastomer element, reducing direct metal-to-metal force transfer.

This design allows the coupling to:

• Absorb startup and shutdown shock

• Reduce peak torsional loads

• Isolate engine or motor vibration

• Protect shafts, bearings, and gearboxes

• Improve drivetrain smoothness

The included outer flange ensures secure integration into the drive system and proper mechanical alignment.

Because Arcusaflex couplings are engineered for industrial service, the ACT4SN kit provides predictable torsional stiffness and long-term reliability in continuous-duty environments.

Why a Complete Coupler Kit Matters

Using a matched coupling element and flange assembly ensures proper alignment, secure mounting, and consistent torsional behavior. Mixing components from different configurations can result in imbalance, vibration, and premature drivetrain wear.

The ACT4SN Reich Arcusaflex Coupler Kit provides a complete, engineered solution designed to maintain drivetrain stability and extend equipment service life in high-demand applications.
