The ACH7NN Reich OEM Drive Coupler is a Reich Arcusaflex coupling from the ACH7 series with NN configuration. This heavy-duty coupling element provides torsional vibration isolation in high-torque industrial drive systems.
The ACH7 series handles substantial torque loads from large prime movers while the Arcusaflex elastomeric element provides consistent vibration damping across the operating speed range.
When replacing the ACH7NN element, separate the coupling hubs axially, remove the old elastomer, and inspect both hub profiles under adequate lighting. Install the new element with all lobes properly seated and confirm the specified hub gap dimension before returning the equipment to service.
