The ACT3WT Reich Arcusaflex Drive Coupler is part of the Arcusaflex series of torsionally flexible couplings engineered for demanding industrial drivetrain applications. This specific WT configuration includes a taper lock mounting system on one side and a bolt-on flange connection on the other, making it ideal for applications requiring secure shaft attachment and easy serviceability.
Arcusaflex couplings are widely used in compressor packages, engine-driven systems, generator drives, and pump assemblies where torsional vibration and shock loads must be controlled to protect drivetrain components.
The ACT3WT utilizes a high-strength elastomer element positioned between precision-machined metal components. This design allows torque to be transmitted smoothly while absorbing torsional vibration generated during startup, shutdown, and load fluctuations.

Functional Design and Engineering Advantages
The ACT3WT Arcusaflex coupling transmits torque through compression of a durable elastomer element, allowing it to function as a torsional isolation device within the drivetrain.
The taper lock system provides a tight, concentric shaft connection without the need for keyway machining beyond standard requirements, improving installation speed and reducing the risk of shaft slippage.
The bolt-on flange side allows for straightforward connection to flywheels, hubs, or driven equipment, making this configuration ideal for engine-driven and modular equipment setups.
Operational advantages include:
-
Reduced torsional peak loads during startup
-
Improved drivetrain smoothness
-
Lower vibration levels
-
Reduced wear on shafts and bearings
-
Simplified installation and maintenance
