The ACH6.1SN Reich Arcusaflex Drive Coupler is a heavy-duty OEM coupling from the Reich ACH series, size class 6.1. This coupling handles the high-torque demands of large portable compressors, drilling support equipment, and heavy industrial drives in the 200+ HP range.
ACH6.1 couplers are specified where standard-duty ACT couplers don’t have the torque capacity for the application. The elastomeric element at this size provides substantial torsional damping, protecting large diesel engines and the driven equipment from the cyclic forces that cause driveline fatigue in continuous-duty service.
The ACH6.1SN is a direct replacement for equipment originally specified with this coupling. Follow the equipment manufacturer’s procedure for installation, paying close attention to alignment tolerances and fastener torque values.
Available from Stark Industrial Products with priority shipping for heavy equipment service operations.
