The ACH6.5NN Reich OEM Drive Coupler is a Reich Arcusaflex coupling from the ACH6.5 series with NN hub configuration. This coupling provides torsional vibration isolation for industrial compressors, generators, and heavy rotating equipment.
The ACH6.5 sits in the mid-to-upper range of the Arcusaflex product line, handling the torque demands of large industrial drives. The NN hub configuration specifies a particular shaft interface that matches the equipment installation. Reich Arcusaflex ACH-series couplings use an elastomeric element that provides controlled torsional flexibility while maintaining a compact installation footprint, making them a preferred choice for equipment packages where space constraints limit coupling selection.
Replace the ACH6.5NN element by separating the coupling hubs axially. Remove all old elastomer material, inspect hub profiles for wear, and install the new element with complete lobe engagement on both sides. Set the hub gap to the dimension specified in the Reich technical data for the ACH6.5 series.
