ACT4.NN Reich OEM Drive Coupler

The ACT4.NN Reich Arcusaflex Drive Coupler is an OEM coupling from the Reich ACT series, size class 4 with standard keyway bores on both hubs. This mid-range coupling handles the torque demands of portable compressors and industrial equipment in the 75-200 HP range.

ACT4 couplers with standard keyway bores are the most straightforward configuration in this size class, compatible with conventional keyed shaft connections on both the driving and driven sides. These couplers are specified across a range of compressor and industrial equipment platforms where effective vibration damping and reliable torque transmission are required.

The ACT4.NN is a direct replacement for equipment originally fitted with this coupling. Install per the equipment manufacturer’s alignment specifications and verify smooth operation after startup.

Available from Stark Industrial Products for compressor and industrial equipment maintenance.
