The ACT6.SN Reich Arcusaflex Drive Coupler is an OEM coupling equivalent to the ACT6SN in the Reich Arcusaflex range. This size class 6 coupling handles heavy-duty torque loads in large portable compressors, industrial pump systems, and diesel-driven equipment.
Large portable compressors and industrial drives equipped with ACT6-class couplers are workhorses in construction, pipeline, and industrial field service. The coupling absorbs the substantial torsional forces generated by large diesel engines during continuous operation, protecting the compressor airend and downstream driveline components from vibratory damage.
The ACT6.SN is a direct replacement for equipment specifying this part number. Follow the equipment manufacturer’s alignment and torque procedures during installation. Verify vibration levels after startup to confirm proper installation.
