ACH9SN Reich OEM Drive Coupler

The ACH9SN Reich OEM Drive Coupler is a Reich Arcusaflex coupling from the ACH9 series with SN hub configuration. The ACH9 is one of the largest standard sizes in the Arcusaflex range, designed for high-torque industrial drives where substantial power transmission and vibration isolation are both critical.

Equipment running ACH9-sized couplings includes large compressor packages driven by high-horsepower diesel engines, heavy pump installations, and industrial generator sets. At this power level, the consequences of coupling failure are severe, with potential damage to engine crankshafts, gearboxes, and driven equipment running into tens of thousands of dollars. The SN hub configuration specifies the shaft interface geometry that mates with the particular equipment installation.

During element replacement on the ACH9SN, use appropriate lifting equipment to handle the coupling components safely. Inspect both hub profiles thoroughly for fatigue cracks, install the new element with all lobes fully engaged, and verify the hub gap per the Reich technical specification for the ACH9 series.
