ACH6.5NT Reich OEM Drive Coupler

The ACH6.5NT Reich Arcusaflex Drive Coupler is a heavy-duty OEM coupling from the Reich ACH series, size class 6.5. This coupling is specified in large industrial equipment, mining machinery, and heavy portable compressors where high-torque torsional damping is essential for driveline protection.

ACH6.5 couplers handle the torque output of large diesel engines powering equipment in the 200-400+ HP range. Equipment manufacturers including Atlas Copco and Sandvik specify ACH-class Arcusaflex couplings in their heavy equipment platforms for mining, quarrying, and industrial applications where the coupling must absorb severe torsional loads during continuous operation.

The ACH6.5NT is a direct replacement for equipment originally specified with this coupling. At this torque level, alignment precision and proper installation are critical for achieving full coupling service life. Follow the manufacturer’s procedure exactly.
