The ACT6SN Reich Arcusaflex Drive Coupler is a heavy-duty OEM coupling from the Reich ACT series, size class 6. The ACT6 represents the upper end of the standard-duty Arcusaflex ACT range, handling the torque loads of large portable compressors, industrial drives, and heavy diesel-driven equipment.
At this size, the coupling serves equipment rated at 300+ CFM in portable compressor applications, and comparable power levels in industrial pump and generator drives. The elastomeric element provides substantial torsional damping, and element condition has a significant impact on drivetrain reliability for the entire machine. Inspect at every scheduled maintenance interval and replace proactively when deterioration is visible.
The ACT6SN is a direct replacement for equipment originally specified with this coupling. Follow the manufacturer’s alignment specifications precisely during installation.
