The ACH4NN Reich Arcusaflex Drive Coupler is part of the Arcusaflex series of torsionally flexible couplings engineered for demanding industrial drivetrain systems. Arcusaflex couplings are widely used in compressor packages, generator drives, pumps, and engine-driven equipment where vibration isolation and drivetrain protection are critical.
The ACH4NN configuration utilizes a high-strength elastomer element mounted between precision-machined metal components. This design allows torque to be transmitted smoothly while absorbing torsional shock loads generated during startup, shutdown, and fluctuating load conditions.
Industrial drive systems frequently experience torsional pulses and vibration that can lead to premature wear of bearings, shafts, and connected components. The Arcusaflex design helps isolate these forces, maintaining drivetrain stability and improving equipment longevity.
Engineered for continuous-duty industrial environments, the ACH4NN Arcusaflex coupling delivers dependable torque transmission and long service life.

Functional Design and Engineering Advantages
The ACH4NN Arcusaflex coupling transmits torque through compression of a durable elastomer element positioned between metal drive components. This configuration allows the coupling to act as a torsional isolation device within the drivetrain.
Operational advantages include:
-
Reduced torsional peak loads during startup
-
Improved drivetrain smoothness
-
Lower mechanical vibration
-
Reduced stress on connected shafts and bearings
-
Longer service intervals for rotating equipment
Arcusaflex couplings are specifically engineered to maintain predictable torsional stiffness while providing controlled flexibility. This balance allows equipment to operate efficiently while protecting critical drivetrain components from shock loading.
Because the elastomer element absorbs vibration and torque fluctuations, the coupling helps maintain stable operation in high-load industrial environments.
