ACH7SN Reich OEM Drive Coupler

The ACH7SN Reich OEM Drive Coupler is a Reich Arcusaflex coupling from the ACH7 series with SN configuration. This coupling provides torsional vibration isolation for heavy industrial drive systems including large compressor packages, pump drives, and generator sets.

The ACH7 is a substantial coupling in the Arcusaflex lineup, handling the torque output of large diesel engines and high-horsepower electric motors. The SN designation specifies the hub type and shaft interface configuration for this installation. Reich ACH-series couplings are engineered for demanding continuous-duty applications where consistent vibration damping is critical to protecting expensive downstream components such as gearboxes, airends, and precision bearings.

During element replacement, separate the hubs without disturbing the connected equipment alignment. Remove the worn element, inspect all hub profiles for damage, and install the new elastomeric element with full lobe engagement confirmed on both sides. Verify the hub gap per the Reich specification for the ACH7 series.
